396/375 hp/motor issues

I have used the Pertronics conversion for years on my boat. It has worked perfect. I doubt that is your problem. Google the wiring for your unit online. I cant rember but I think you have to eliminate the ballast resistor. If the ballast resistor is still in the system that could be causing some issue. Also some ignitions used a resistor wire. Run new wiring to the coil and pertronics unit.
