Question Bypassing burnt resistor wire

I have a 69 Camaro SS3986 which has a solid state electronic ignition conversion installed. It was installed when I purchased the car. The resistor wire which connects to the positive coil terminal burnt up. A friend told me I should bypass the wire because I need 12 volts to the coil with the solid state ingnition. Per a wiring diagram I spliced onto the pink wire under the steering column and ran a 12 guage wire through the firewall to the coil. The car starts fine. However, the generator light does not come on with the key on like it should. The turns signals do not work and the genertor light flashes with the turn signal. Also the parking brake light does not light, however the generator light comes on when the brake is on.

Any ideas as to what I did wrong?

Re: Bypassing burnt resistor wire

that's out there, and I'm not real big on 69 dashes, but it sounds like you lost the ground to your dash. Maybe something came loose while you were under there?

Re: Bypassing burnt resistor wire

There are two pink 12 gauge wires. One comes from the ignition going to the firewall connector and the other goes to your steering wheel harness. It sounds like you spliced into the wrong wire. The resistor wire should not have fried itself unless there is a short along the line. Fix the pink wire on the steering harness and get your 12 volt source from the pink 12 gauge wire going to the firewall connector.

Cool Re: Bypassing burnt resistor wire

Ok. I will take your advise and let you know how I make out.

Thanks,

Re: Bypassing burnt resistor wire

OK, I spliced the pink wire at the steering harness and picked up the 12 volts for the coil at the pink wire close to the firewall connector. Everything works fine and she starts and runs beautifully. Thanks for your support!

Concerning the root cause of the burnt wire, isn't it possible for the resistor wire to deteriorate over time. Also, could the wire have burned up based on the fact that the electronic ignition requires 12 volts and was only getting 6 to 8 volts through resistor wire. A mechanic has told me this problem is common.

What's your thoughts?

Re: Bypassing burnt resistor wire

hmmm never heard that one?
everyone thinks the resistance wire gives you less voltage?
itll still give 12 volts
but current is somewhat diminished hence resistance.
you can still use the resistance wire on most if not all aftermarket ignition systems.
the resistance wire is part of the switching circuit from the ignition key.
power to the aftermarket box is provided by the battery.
resistance wire was use so that the old points ignition contacts would not wear out as fast.

Re: Bypassing burnt resistor wire

The resistance wire by design dissipates excess energy as heat. I suspect that over the years it has become rather checked and tattered. I doubt your electronic ignition caused it. A more likly cause would be a direct short to ground at the coil, or the key was left on for an extended period of time back when it still had breaker points in it.
