Thread: wiring connections

thanks mate, will take another look tomorrow arvo after work and see how I go Thanks for your help!!

Connected the green and red wires together, bypassing the ballast resistor. Turned the key to the ON position and the car would fire and keep running. Strange that I didn't have to turn it to START. Kind of proves that the coil is OK. Will have to go shopping to see if I can find a resistor locally. Fun times ahead trying to get the local shops to match it up

Contacted Repco, they have a universal 1.06ohm ballast resistor in stock, $6.50. Will call by this arvo and see if that does the job. No idea what the rating on the original is as there was no writing on it.

Well the outside of the box said 1.06ohm and the actual resistor says 1.6ohm

Put it in and same problem, turn key to START and it fires, turn it back to ON and the engine dies.

Spoke to a mate tonight and he suggested the two way female spade terminal may have been a diode. He's going to see if he has a 12V coil and may simplify the ignition system.

Not wanting to sound flipant, but if there was/were a diode(s) in place - surely it would be easy and cheap to just replace the diode

It would make sense that there could be a diode stopping voltage travelling back towards the resistor after starting.

yep, to me it just looked like a 2 way female spade terminal, but maybe the diode was inside the heat shrink. Will check it out tomorrow. You're right, it will be easiest to do that, just if we have the other things handy (he's a auto electrician) will do any easy jobs to upgrade things, well anything to make it a little more water resistant

Found the problem, there was a one way diode hiding in the small length of wire I cut off with the 2 way female spade connector. Just cut the green lead that was going from the starter solenoid spade terminal and it worked fine. Problem was that wire was feeding 6V from the ballast resistor back to the starter solenoid since there was no one way diode.
