Customer Question

I have a onan marquis gold 5500 Generator 5.5HGJAB 1038C
I have replaced fuel pump and carb. Will run great one time over night or on trip, next time will run for a while then die and not restart for a while. I tried one night when having trouble leaving door open, worked. shut door and it died in a couple min. The motor will crank fine, but fuel pump will not come on till it sits a while. I have tested pump and would run on separate voltage. I get a 3 fault with a secondary 4 - 7

Hello, my name is ***** ***** I am going to assist you with this. Code 47 is Ignition Fault. It sounds like one or both coils are breaking down due to heating, and then recovering once cooled. It is a very huge job to replace a coil. The genset must be removed from the coach, and totally broken down to get to them.Due to this fact, I usually recommend replacing both coils when doing this.
