Dave,
From what I have learned from my own experience and from writings on another forum by an Onan Generator repairman, you need to hold the stat switch until the alternator is putting out enough power to hold the fuel valve open. If you release it as soon as the engine fires, the fuel solenoid will go to the off position. It is only the battery power that is keeping it open while cranking. As soon as the engine fires, the bendix should disengage and the starter spin freely. It only takes a couple of seconds for the power to come up enough to hold the fuel solenoid.... Hope this helps.

Thanks George,
However, it is when I hold the switch in that I get into trouble. It usually will not continue running and that is when the starter stayed engaged even after I let go of the switch. On at least two occassions it cranked until I got out of the bus and pulled the quick disconnect for the batteries. That must have been a couple of minutes of cranking and it still did not catch.

Dave, put a new fuel pump on it. There is a pin hole in the diaphragm of
the mechanical lift pump.

Are you preheating before attempting to crank the gen. Howard Camilla, Ga. 86 PT40 [Non-text portions of this message have been removed] |

Dave this is probably too simple an answer to be worth much, but
I had the same problems with my Onan genset on my 90SP36 and it turned out to be the reset button on the interface box.

Hi Ralph,
Sure is good to hear from you. Thanks to you and the others who have helped. There is no perkins dealer in Tulsa, so do you know if someone else carries the pump? Thanks again.

Hi Tom,
I am wondering if I have messed up on your address since I haven't received anything back on the gen project. Of course I know how busy a guy can get. If we have lost our connect somehow I will resend Dave in Tulsa (1984PT40) |

I have been a watcher for some time now. Now I have a question for
the forum.I have a 1983 BB 35PT with a Fidelity Loadstar Synchronous Generator. KW 12.5,KVA 12.5, Volts 120/240, amps 52 rpm 1800, Phase 1, serial # F3047BE-9UM, Model F3047BE. I need to talk with someone who has parts, can work on this gen,or tell me why its loses its load. I have replaced the breaker. The Gen runs fine. It will start right up, but after running 30 minutes give or take.It would lose load,run the gen out hit rest and back in business now the squirrel has gone on vacation.

Richard here, on the new generator I put in, still can't start with
controller on outside, found short in starter solenoid thats on top of the starter, jumper the #5 wire to the #5 terminal in the controll box, an can start the generator from the outside, can shut down from the remote switch, looking for shorted wire in harness now. |
