So, I was able to swing getting a 77 35 HP Johnson for free with a boat. Problem is, wiring was super Jerry rigged and I am fairly confident the guy had it all messed up. I replaced all of the wires however, I keep blowing the fuse every couple of starts. The wiring diagram had shown no ground coming from the starting solenoid. There is a ground going to the ignition switch however I have nowhere to route it to actually ground. Bottom line, I need better wiring diagram before I fry something. Any advice? Just want to get out on the water, PLEASE help!
