I have a 69 plymouth I'm converting to the orange box, new style regulator, and two field alternator. The car previously had a crude engine harness on it wired to an ecu with solid state reg and no alternator. Just enough to get it on a trailer, but mostly ran really well, started on first crank. It came with a brand new oe engine harness. First issue I had after wiring, car would start then stumble and die. I figured out I had to reverse the polarity on the distributor to get it to run. Doesnt seem right to me.
Next thing, the car was running without an alternator when I got it. As I was trying to troubleshoot all this, I noticed it won't run without the alternator hooked up anymore. It would only start with the key in the start position. I replaced the ballast resistor. Same thing. You hook up the alternator and it fires right up, but runs sorta rough. Battery has 12.5 volts also. Is that right?
I've tried multiple coils, ballasts, and ecus
