Built a 29 dodge 4 door, used a 73 dodge 360 and 727 in it with the Chrysler charging system just like it came out of the motorhome it was in. Parked all winter, flashed it up and the lights and voltmeter pulse like mad, it was a minor problem last year but manageable. The voltage regulator is a solid state unit, what I want to know is how to fix this problem. It seems to be fairly common on dodge car websites, I wired the car year before last, the charging system works fine except for this pulsing thing. And yes, that's my ugly face.
