Starter Motor

[Chief]

Hey guys I think ive wired it up right but its not cranking over?

ok information, I have the neutral going to the front left strut tower on of the three bolts as my battery neutral, and i have 2 wires running to the starter motor the big thick one.

The trigger wire which i believe to be a positive trigger switch i put on the positive to the battery which i believe should make it crank?

 

Is there anything else i am missing like a ground for the Starter i figured it should be sweet because its bolted to the bell housing or is the trigger neutral but it show's in the

picture in the knowlege base in this section the trigger to be positive http://www.rollaclub.com/faq/index.php?tit...Starting_System

Ive had a look around but came up with nothing.

 

As it show's in the picture i have the constant on top and the trigger the bottom what am i missing?

 

Cheers guys thanks for you help

you got a decent ground on the engine from the chassis?

i suppose not i was just thinking about it but i figured it would be ground by the engine mounts? would the rubber interfere?

nah mate, rubber no good for conducting electricities. rubber is an insulator.

 

you need a proper ground "strap" on your engine.

 

basically find a chunky wire, and bolt it somewhere on your engine, and then bolt it somewhere on your chassis.

 

if you don't have one, they sell them at supercheap for pretty cheap. chunky bit of wire with rings at each end for bolts.

yep thats the one!

 

just give the surfaces your gonna bolt it to a quick scratch up, make sure there is a bit of bare metal.

 

also just a side not, your engine guages and instruments (temp, oil pressure) wont work unless you have that ground on.

thanks DAVE

 

You saved me making another thread hahaha

 

Cheers man

Heeyy ITS WORKS!! it cranks over but its quite a slow crank? its it still good? with the i think its a 3K starter should it still be good and I'm pretty sure the engine has a massive amount of compression (due t the head being shaved a lot ) ill have to get a carby and see if its enough to start the car.

 

thanks again man

[ke70dave]

ah good to hear mate

 

I'm unsure on if a 3k starter is good enough, it might be a little sad perhaps? running low on brushes?

 

battery charged up?

 

see how you go with the carby though!

[Chief]

Yeah its probably shitted it turns it over so it should good enough with the help of internal combustion lol but that will probably have to be upgraded later on.
