I have a GAS Onan Emerald plus 5000 genset model number 5BGEFA26100P.
I was cleaning the outside with brush and soap, and had it running the engine and the genset. got through cleaning and not paying attention to the gas hand, The cover was down over the genset so no water could get in
when the generator just up and cut off, it did not trip anything, it just cut off while under load.
Thinking it was because the gas hand was below 1/4 tank I had her filled up.after this she wouldn't do anything but click when the start push button was pressed on the genset
I then checked the oil level and she was a little low and I brought it back up to the line on the oil dip-stick.
The clicking was coming from the starter solenoid part#307 2570. I thought it might be bad so I ordered a new one and placed it on the Unit and couldn't get it to do anything, not even click any more so I jerk the 2 old batteries out and replaced with 2 brand new ones. checked and triple checked all grounds and positive post terminals and cables, still nothing. thinking I may have just bought a cheap starter solenoid off of e-bay I decide to buy the right one that should have purchased from the beginning,
checked and blew out the Oil sending Unit,
when I hooked everything back up, and went around to connect the batteries the genset tried starting to crank by itself like the start button was being pressed i pulled the wire back off the batteries and it wouldn't do this again. I think I had the 2 wires on the starter solenoid COIL backwards so i switched them back.
the switch on the dash is disconnected just pulled the wires off to take it out of the equation
So with the new starter solenoid in, still get nothing when pressing the switch
I am pulling my hair out over this, please help
