Re: Onan 6.5 genset problem

But when going to start it back up after running it for a while- it didn't want to start. It had to sit for about 5 min before it would start up again. The mechanic told the broker " those have circuit boards and they are designed not to start up right away after running"." Let it sit for 10 min and it will start up." That doesn't sound right to me That mechanic is full of the stuff that cats bury in the flower bed.562Views0likes0CommentsRe: Cummins Filter Recall

You'd better hop he does use an after market filter. Apparently theu are not affected.221Views0likes0CommentsRe: Onan Generator Stopped running
Have you tried a fresh set of spark plugs? If it tries to start it is getting fuel and getting ignition, just not enough of or too much of one or the other, first guess would be fuel. Very doubtful it would be the controller. If you can observe the throttle/governor linkage, does it move when trying to start? Try over riding it when trying to start it, don't allow the engine to overspeed/run too fast.394Views0likes0CommentsRe: Onan no start

These 2800 Onans (I've owned 3) get the starting ignition current from the battery while cranking, but change over to self-generated power when the start switch is released. Both of my similar failures have been failure to produce voltage; once under warranty, it was the rotor/stator, the other time it was the voltage regulator. Fairly easy to diagnose with the service manual and a volt-ohm meter. There's also troubleshooting steps at the Flight Systems website. All 3 of mine were built after they deleted the low oil switch. Not sure about yours. If you have it, it's a possible source. Also be sure you're checking the oil level the right way. For all of mine, after wiping the dipstick, it's to be rested in the lip of the hole, _not_ screwed in. If you read it after screwing it in, you are always low on oil. Good luck with it. They can be dang frustrating. Jim, "Instant human, just add coffee." Great advice here.308Views0likes0CommentsRe: Onan MicroLite 2.5 LP series L
The greatest majority of dry fuel genset problems are fuel system related. Having said that, start with a new spark plug correctly gapped (different from gasoline). Check your gas regulators, both of them, look closely at the vents for evidence of bugs build homes in them.1.5KViews0likes0Comments
