i have a j50belct and what i believe is a 55el79c. Both wiring harness are similar but both have been hacked and spliced into before i purchased. I had originally bought a boat with the j50 but had compression issues and lasted only a couple of weeks. So i found a 55 that compared nicely for pretty cheap thinking i could swap parts back and forth. These motors have been giving me a heck of a time and just want to get one working properly. The 50 needs new sleeves, pistons, etc but the 55 has great compression and all new electronics. I have taken the 55 to a local shop and they said it is a great motor but they dont know why it is sneezing or stalling. Mechanic says he thinks its an overheat issue but they will not work on it tune it up until the warning alarm and sensors are hooked up properly. The mechanic assured me i could do it myself and save the $95/hr charge if i found the diagram but i am completely stuck right now. I am looking for the proper wiring diagram to wire the warning horn, kill switch, and temp sensor into. i have found one on google but when i wired it up to no avail did the warning horn work. Even tried directly grounding the temp sensor wire at the block and remote control. Also on the quick disconnect plugs, on both motors, the rempte side has 8 wires going in and only 7 wires on the motor side. Any help or advice would be greatly appreciated. i know johnsons are supposed to be fairly easy/fun to work on but i am having a nightmare not being able to get on the water and fish. Thank you guys in advance.
