Just dropped my new engine in and replaced the wiring with a new one from Z & M Jeeps. Really nice quality and US made. Everything plugged right in. But I do not have the required 6 volts to the coil in the run position, I have 12 all the time. I found the resistor wire in the harness and it does not appear to be a resistor wire. (no markings of any kind) So I unplugged both end of the harness and took a ohm reading and nothing, same as any regular wire, no resistance. I have a no starting condition after it is up to operating temp. and sometimes will shut off at low idle speeds. My question is this, what affects does constant 12 volts to the coil have on the ignition system? So far I have replaced ignition switch, coil, pick up coil in dist., starter solenoid and ignition control module on fender.
