Thread: wiring connections

there should be two wires to the coil +ve terminal.......

one should have 12v for when cranking.......which will drop due to the starter motor........

the other should have about 7 or 9v with the ignition in the on position......
if there is a resisitor fitted......


also.....if you wiring was brittle like you say.....it may have broken inside the insulation when you were moving things around........

Do you mean the spade terminal or the actual +ve post that the main battery lead goes to?

i mean the ignition coil.......

if the starter cranks when you turn the key.....then its obviously working just fine......
and the engine starts......


but as soon as you let go of the key.......it shuts down.......

this tells me that the coil isnt getting an ignition feed.....ie...no power when the key is on reds......

i dont think this has anything to do with the starter wiring....unless one of those wire was from the coil and you have moved it to the starter......



do you have two wires going to the +ve terminal of the ignition coil.....?

No wires to the coil were touched. There is a small white box (resistor) that feeds to coil. Has 2 green wires on one terminal and one red wire on the other terminal. May help if I get some pics?

ok...thats near enough.......you will notice one of those wires goes direct to the coil.......
the other passes through the resistor first.......


with the ignition on......check the voltages at the resistor.....at both ends of it......

one end should have 12 volts.......and the other should have a few volts less......
if you are getting no volts through the resistor then it may have burnt out and gone open circuit......
if you bridge it and the car starts and runs.....then its the resistor playing up.....and will need replacing.....
do not run the engine too long with resistor bridged out as you may damage the coil......



did you get all that.....?



oh.....ok.....
what i just said was.....join the two terminals on the resistor with a bit of wire.....then start the engine.....
if its still running when you let go of the key.....you need a new resistor......
or a 12v coil......

Its 10:30pm here but just went out and checked. Get 10.6V on the red resistor terminal that appears to go back to the starter motor.

The other terminal on the resistor (hidden in the picture) has 2 green wires to it, and reads 1-2V. Smoke comes out of this terminal if run for 30sec with key in ON position which is never a good sign.



Haven't cross a wire across the terminal yet. Need the missus to come give us a hand so I can play in the engine bay and get her to work the ignition key.

Went to bridge the red and green wires this arvo but stopped after I pulled the orange juice bottle (waterproofing) off the coil and saw several wires so I wasn't too sure which I should be connecting together. This is the wiring diagram I did up. Not sure if the red/green wires go direct to the starter but they go in that direction. There is another little silver cylindrical (resistor) box with just a single black wire going to it that's screwed next to the ignition module.



By the looks of it should I still be attaching the red and green wires and bypassing the white rectangular device which I am assuming is the ballast resistor.

the diagram all looks right......except for the bit that says to starter......

they should be going to ignition somewhere.......or at least the red wire should......the green can go to the starter......



if youve joined the two together that could cause headaches.......




and smoke coming from conections usually indicates bad connections......
