Car Electrical

Alrighty well I had a bitch of a time doing this so I thought I'd put up a guide specifically for k engines. I've got an otherwise stock 4k-c engine in a 1980 ke55. before you start - i'd like to say that I'm pretty much re-writing a guide on toymods on this topic. I'd also like to point out that this I'm writing this for people like me who are new to the world of auto-electronics. If you're electrically minded you can probably skim over a lot of stuff here. If you ruin your engine or anything I take no responsibility... i don't know how you could do that, I'm just saying. There are other ways of doing this, such as finding a dizzy that suits that has an inbuil…

I have created a new sub-forum specifically for car electrics, Please feel free to post your questions here. For those of you that may not know, I have recently started an apprenticeship in automotive electrics. I'm still learning but I have a fairly good knowledge of certain things (KE70/AE71/AE82/AE86/Starter Motors/Alternators etc). Even if I don't know the answer I can possibly find out through my boss and co-workers if you need an answer on something. Keep the posts coming.. Oh and by the way, If you live around Brisbane I may be able to help you out with auto electrical work..

hey all just wondering if anyone has any ideas bout my cressy??? i bought 1j cressy not running being told that was running had just been sitting for some time long story short new battery new fuel no start.. ended up having to re wire injectors(which were also blocked) coils and ignitor.. all there now still no start!? rpm signal ok at ecu and signal coming from sync also so crank/cam are sending signal,,, ecu set up and checked by tuner and all seems a ok... anyyy ideas?????????????? cheers is driving me nuts :D ;)

Hey, I was looks for a quick and simple power upgrade. My 16v 4age has had some minor head work, (port polish and grind), iridium plugs, 2" sports exhaust, Airpod, Turbo muffler, always run 98 oct premium fuel, 100% synthetic oil and all filters changed. Power steering and A/C pumps and belts taken off too just to get a few extra KW. I was thinking about getting bigger cams.. 272 deg and HKS cam gears but need to get an after market ECU Eg.. Haltech or something. The cost of getting one is quite a bit not to mention getting it tuned so going to hold off and maybe get a Gze from a Levin ae101 or something (all just thoughts for now) :wink: So another thing is that …

Hey guys, i'am trying to get my KE55 roadworthy, couple of little things that need to be done, - First of all is the fuel gauge, it doesn't move at all, i have checked the gauge itself and tested my KE30 one in there and it still doesn't work, i then checked the sender unit and took off the plug going to it, cleaned it and still won't work, can anyone else think of anything else? Lastly i took off some of the emission shit, will they knock that back for not being there? Thanks Trent

first off you need a vl 80amp alternator witch looks like this make sure you get the loom connector that plugs into the regulator! also grab a couple of regulators just in-case the ones in your vl alternator are worn! step 1 - dismantle the 4k alternator and vl alternators. step 2 - swap all the internals from the vl alternator to the corolla casing and use the vl fan (more fins = better cooling) step 3 - now remember those 4 LONG bolts holding the casing together? you need to find 2 about 2cm longer (i got mine from a 5k starter motor) step 4 - install those 2 longer bolts with the rear bracket and bolt it all up step 5 - install the regulator…

I have no spark coming out of my coil on my 79 ke55. Have tried everything to get spark out of it. The coil is only about 18 months old and worked previously. The only thing that I have done is put another 4k motor in with a 5speed manual, the car was previously auto. The car was running with the auto in it but now won't get any spark. I'm using the original harness to the car. Can anyone think of why I'm not getting any spark

what will be the main reason for a car sort jerk while accelerate..? it happen when i gas on to reach a normal speed to 60-80km/h * engine model 3k (4 speed)

Hey gents ive got this show room ke20 and the last thing she needs is the alternator wiring done does anyone have a wiring diagram that can help its a 1974 with a 4k. Its the only thing I can't figure out and don't want to mess it up

Ok so I'm putting a turbo onto my 4age soon enough but the drama for me is what ecu i can use, just wondering what people have run in theres? -haltech -motec -microtec -autronic..

Hey guys.. this might sound abit dumb to some but how does a microtech package come.. I'm lookin at buyin a LT10 package'brand new'.. for my 4agte but what else do you need for it to run car.. as i hav not 1 bit of Stock wirin harness,but injector plugs.. Like as i mean does it come with all the wirin to wire my engine to ignition ??? A history lesson would be good thanks... Cruise

So my KE30 is a 1975. has the external regulator for the alternator and what not. since i've had the car the low beams have not worked. the lamps and globes have been replaced. there is box on the passenger side that the headlight wires appear to run into so i would think that its the relay. 6pins! but on the box it says tail relay? my question is... has anyone else had this issue and how did you go about fixing it? ie. replace the relay with another one? buy a new one? (if yes then where and how much) or for someone cluey with electrics did you split the relay up? and have a couple of seperate ones to control tail lamps and headlights? cheers, Lu…

So as the title says my car won't idol it starts then stalls, but a before I go into full detail ill give you all a bit more info on my car Ke70 with 16v 4age Motor and loom from ae82 corolla bigport first gen with map sensor I had installed the motor and had the engine running at the start of the year I even drove the car up the drive way but I had put the car in the shed and hadn't started it for a few months as I was fixing rust and working on my other car, But the other week I went to start it and It wouldn't start it would idol then stall! I have fuel at the injectors and fuel pump works fine it's a vn commodore in tank pump that I have modified to f…

Hey, i have got a 5k motor in my sierra ute and it has the points type dizzy. I am wanting to put an electronic dizzy in it so can someone tell me what cars i can get an electronic dizzy that will fit into the 5k motor. I know about changing the coil over to have the ignitor and that but i just need to know what cars i can get one from so i can start to search the wreckers. Cheers

I think I had a thread about this before but I want to start a fresh one as I did a bit of work tonight to try and figure it out. The problem: Intermittent starting issues, sometimes it will start fine, other times the starter motor will struggle, even stop turning over. Sometimes when it does this it will run but it will run like complete crap blowing black shit out the exhaust. Things I have tested: The starter is hard wired to a push start button, I bypassed the button, its fine. When the car is in the on but not run position the starter motor will crank fine. In the ON position it will occasionally struggle to crank, when it does this my volt meter will…

Hey I had my 4age running ruff but running .... And I come back the next day turn it over nothing, foot flat too the floor a little splutter of life. So I check the timing by turning it over its out. Getting it close by hand -5 deg, move the dizzy the slightest and it gone way off the grid. There is uncovered metal on my rotor down the face of it

Hi, I was just wondering has anyone on this list done battery relocation to the boot? If they have will it be possible to shed some light on this issue like how and where they run the wire what gauge they used and so on. And if possible some pictures? Cameron

hi all, i have been building this car for a while now and ive finally gotten to a drivable point. but my bettery kept dying and the charge light wouldnt turn off. so upon investigation i found that my alternator isnt connected. the problem is its not an original one and only seems to have place on the back for the positive wire to screw on and one other wire to plug in. the standard ke20 wiring loom has a three wire plug as well as the positive wire and one other wire waiting to go into the alternator. ive been searching all morning to try and find what i need to do but i don't understand much of what ive read. so if anyone could please help me or point me in the…

First of all I would like to say I hope no one else has posted this topic as it is my first post..so here goes: I have a wonderful little green ke30 that i got for free (thanks granny) anyway i was curious about changing the lights in my dash to leds, could someone please tell me whether i can get a special type of LED that will fit straight into the normal bulb holder, or if i need to modify a normal dicksmith Led to fit, if so what resistors e.t.c should i use.. by the way I live in New Zealand. p.s. i have already removed the gauge cluster twice to install a 2" tacho in the clock hole, so I'm a little familiar with it

i have a bigport 4age in an ae71 with stock computer when i bridge/short out the diagnostic port/check connector the idle doesnt change and the timing doesnt either. i have two ecu's one i set the timing at 18 degrees with diagnostic port shorted or not and it makes the extractors very very hot. when i plug in the other ecu it say 10 degrees with the diagnostic port shorted or not and still makes extractors very very hot. i looked at the wiring diagram and the diagnostic port is pin "T" then to ground, so i opened the ecu and and grounded the "T" pin and it still didnt change. so I'm a tad stumped at this point if anyone can shed some light that would be gre…

Okay since I searched and found no info for people how to wire up a 5k electronic distributor I thought id make a topic to tell users. This is on my ke20 corolla so some things may be slightly different between models The 5k distributor is a pulse generating type with in built ignitor (ignition module). There is a two pin toyota connector with a black wire (negative) and a black with orange tracer (posative). Remove your old points distribtor, the 4mm black wire going to the distributor points is connected to the black wire on the two pin plug (this is negative switching for your coil). Connect the black with orange tracer to the posative side of your coil. …

been told to take it out, is this a good idea?

My KE30 turns 50 next year, & I've planned on giving her a few extra features for her birthday. (I'm only Her second owner) One of the presents is to replace or modify, all lighting, inside & out, with LED lights. Headlights are pretty easy, as you can easily source "H4 bulb compatible" 4 sided LED Hi intensity lights bulbs. I've ordered a set this week, so that will be the first step. One of the best things you can do to an olde Rolla, is increase the capacity of the battery & alternator, although replacing the original crappy load bearing wiring, with cable a lot thicker, would be a close second. (I've already done that) …

Hi, Just messing around in the shed today with some alternators I have seeing what I can do for an up grade into my KE30 as the standard one now with a stereo on it is having trouble keeping the car charged. So I got out my old KE70 spare I have and another Bosch one I have unknown origin but it is rated at 70 Amps. At first look the body of the 70A one the mount was similar to the rolla one but it was about 10mm to long so it wouldn't fit. Could of used a spacer but that is messy. So I did a bit of fiddling and found the body for the KE70 one is the same size as this one. So I began pulling the 70A alternator apart to get the insides out so I can put it into…

Gday guys, my 35W 6000K HID kit will be in my '55 in a few days. Wanted 4300 or 5000k. Just curious, and yes i did search, how many people have done a HID setup before on their rolla, and how satisfied were you? Yeah yeah, i know its illegal to do it on a car that wasn't manufactured with it, but i drive mostly early morning and late night in the country. 2 of my mates have done HID setups, and never been hassled by the cops. Let us know. Thanks, Luke.

Hey fellas, just trying to figure out what the problem is with this 4k-c not sparking. It cranks over and everything but just doesnt spark, it has new spark plugs, new coil, new battery just wont fire. Old mate I'm buying it off thinks it could be an earthing problem, just wondering if anyone has come across the same problem?

ok ill start with a bit of history, its a ae 92 seca sx 4age .its got fuel power at coil but no power at dissy no spark at plugs .after any idea,s on what could be wrong .thanks in advance.rick

the battery is in the boot of my ke70 currently have the earth bolted to chassis and then have a seperate wire going from the block to chassis is this right?

Hi all, I've been away from rollaclub for a while, at the moment I am building an AE71 with JDM bigport and JDM fuel tank. I am stuck with too much confusing information regarding the wiring. I have a circuit opening relay. I have one of these http://www.jaycar.com.au/productView.asp?ID=SY4076&CATID=79&form=CAT2&SUBCATID=979#1 And i need to know how to make it all work Ive grounded the earth wire from the fuel pump in the boot I also came across this: White/Black - Wires to to STA - Starter/ECU Start Signal. White/Red - Wires to EFI Relay - +12v Ignition Switched power (Run through a suitably sized fuse, 10A is us…

hey all i was just wondering on how to set up a kill switch in my corolla? any help is good help

hay i got a taco and shift light for my t18 yesterday followed the instructions o how to wire it and i thought id try get the power ground and batter from where u wire your stereo to the cars wires had it all conected didnt have the rpm cable connected yet tested to see if i had everything right before this it was it was lighting up ect then when i conected the rpm wire to the bolt thing on the dizzy it all stoped working including stereo all the fuses arnt blown sooo.... i think i just killed it all :bash:

Hi, just a quick question here. I'm getting no spark from the coil, i've replaced the ignitor, leads, plugs, rotor button, cap and points. The one thing I am unsure of is how to set the points gap. I know it is ment to be arount 0.8mm but where are you getting that distance from and at what point of the rotation? So is it that I need to rotate the engine and make sure that the point only ever gets 0.8mm closed? Or is there an easier way? Cheers guys Alex

Gday guys, I've called it a day. Nearlly giving up on the whole car ha. I have a KE26, I'm putting an engine in atm, with a single sidedraught. Let the picture do the talking.

temp gauge is not working at all but all other gauges work and the interior light does not work at all. any help at all would be awesome!!

Hey, i bought a programmable ignition system from Jarcar some time ago for my Ke35. i finished building the electronics and got stumped over plotting the original igntion timing values. I have read the manual and it pretty much says to use the timing marks on the crank pulley, also another method is to use a secondary coil pack and an ellaborate setup. So i guess if someone knows the advance curve for a 3k motor or an easy way to plot the original curve it would be very helpful.

Anyone got a pinout /el.drawing of a 7KE ECU ? Was hoping for a bit more than whats in the FAQ Cheers

Bought new battery after last new battery died after 2 weeks of being connected only drove a little bit each week, new battery won't charge at all on old alternator so I bought a new and it had 3 terminals when the plug has 2. Either I rebuild the old one, see if it works or ʞ©$ɟ around with the new one. Can the voltage regulator if faulty, stop the alternator from charging? A lot of questions I know! I'm new to this please help

Hi all, just wondering, i have purchased a Smallport and its got 2 looms, one loom i have plugged up to the engine and the other loom I'm not sure what it is? Its definitely different to the engine loom, is it possibly an interior loom? and the smallest plug that goes into the ECU has cut wires, where does this go to? And can I run my original interior loom with the ECU? Also, is there any plugs on the engine that wont need to be plugged in at all? Any help will be greatly appreciated!

tryed to start the rolla to move it for paint , now i have no spark at the plugs , i do have power to the coil and its earthed,

I have moved along and fitted an electronic dizzy, one that KE Motorsport sells. Certainly cleaner at low revs or when cold, and I just added advance until it felt OK. Today I plotted an ignition curve, and I found I was running 18deg static advance to make it get up and go! So I've reduced it back to 8deg and plotted this- One set of figures with the vac unit on, one with the vac unit disconnected, and a Piper dizzy chart for comparison. That is what the Honda Accord uses, and is similar to the other dizzys mapped here- http://www.jcna.com/library/tech/tech0015.html I think the car feels much better with more advance early on, and I wondered who has had the…
