Ignition Coil ballast resistor HELP - 1983 460
I have a 1983 Jamboree with 460 ford engine. I have burned out 2 coils in the last 200 miles. Not sure what is going on. 2 questions, I do not see an external resistor, where would it be or what would it look like? I also noticed that the previous owner added an electric fuel pump and they chose to tap the positive lead of the coil to feed 12v to the fuel pump, is this a potential problem? They cut the positive lead about 4 inches before it gets to the coil and put in a wire for the fuel pump and tied all 3 together with a wire nut. When it does run on a new coil it runs excellent up until the coil blows. The second coil did not just completely blow just ran really terrible (no power/ misfiring) until I replaced the coil. The 3 coil just flat blew and the motor never started again until I replaced the coil and is running great again for now.....
