Onan 5.5 HGJAB-6755D spec D isnt charging gen set battery
« on: November 21, 2016, 10:31:08 AM »
Good morning all, I am new to this forum, I will get to my question. I have an Onan 5.5 HFJAB-6755D Spec D gen set, it was running good in the morning, shut it down, went hunting, came back that evening fired up and after about 15 min it would begin to surge like a heavy load was added. I checked house battery, it was 13.5 v, then checked the gen set battery it was at 12.05 v (I checked while running and surging). Generator shut down. I had a 2500w portable gen on hand so I hooked up my cord to it and it shut the 2500w gen down. I then disconnected the gen set battery, started the 2500w and it ran just fine. I did not check codes on gen set, not sure how to do that, I bought this toy hauler used....so enough said. Any help would be helpful, thank you!
