Hey just changed the battery on my corolla today and now when I try and start the car I don't get reds just my radio intrieor light and tachometer come on, using the lights, trying to turn the motor over, and hitting the breaks all kill the power completely then if I turn everything off and take the key out for a min it will do the exact same thing, anyone got any ideas as to what this could be? Cheers

New battery sounds flat or dead, have it tested at Repco/Supercheap/Battery World for free. Or if you own a multimeter, set it to DC volts on the "20" setting and hold the probes against the battery terminals. If the reading is less than 12 volts your battery is flat.

Tried new battery same thing happend tested with a multi meter and it's reading 12 volts... So idk wtf is going on can anyone help?

Check the leads on the battery, which I'm sure are clean and tight, then check the other ends of them on the starter and the chassis. Then check the lead that carries power back from the motor to the chassis. All these should be clean & tight.

 

After that start on the fusible links in the main wiring lines and whatever else is wired in on the battery +ve, because it sounds like a bad connection in somethng that got disturbed when you moved the battery wiring. All the connections get old a corroded with time.

I checked all the grounds and connections I could find in the engine bay and they all seem fine, I'm thinking its a fuseable link somewhere but I have no idea where they are. The only one I've found so far is sweet, also the heater and wipers are working now and I'm pretty sure they wernt yesterday, another strange think is even with the tail relay disconnected it still kills the power completely when I hit the breaks or switch the light on.... Even tho nothing happens

 

Just had a play around for a couple of hours with the multi meter, tested connections on the battery, alti and starter and they were all 12.63 vaults, checked the grounds all 12 vaults, one of the starter relays seemed a bit dogey with a shit ground and was only reading 12 vaults on the wire directly to the bat so I switched it around and still the same problem, also the main fuse panel isn't reading 12 volts on anything apart from radio and wipers and when the power shuts of cuz u hit the breaks or turn on the lights u can see the power drop on the fueses to 0.01 and when u release the break or turn the lights off it comes up a lil bit but not much. This has really got me stumped and I'm way to poor for a auto electriton :/

So.. what brings it back up after a circuit has died?? Does something re-set by itself after a while and the circuits work again?

 

Here's the KE70 circuit setup, yours should be similar.

Ok turns out it was the fuseable links I'm in the process of changing them now but I lost my dash lights every thing else works bust those

Changed another one today and I got everything else exept dash lights n spark, also my tachometers shift light is on and it's displaying 5000 rpm and fluctuating a bit if that helps... Anyone have any knowledge to what that could be?
