Re: johnson 35 -1999 problem
The plug on the front of the power pack with the yellow and black wire, the two tan wires and the white and black wire. The yellow and black is the kill circuit. The engine won't shut off by the key with that unplugged. With that unplugged and the two yellow wires disconnected that go to the rectifier should remove all electrical interference. Do you have a timing light you can plug it onto each wire as it is running to see if it is dropping a plug.
