Question Onan Generator

The lpg generator on my 2005 MB Cruiser won't stay running and is likely due to stuck or broken oil switch. Has anybody removed the generator from the MB? It looks like the opening is too small without removing the entire door frame. Also wondering where the gas hookup is. It's really tight in the compartment!

It could be sensitivity screw being out of alignment. See my post in rv.net forum.

I understand that these Onans are soooooo sensitive to their oil levels. Make sure that you give it a " bit" more above the max level. Also Onan no longer has this sensitive precise oil level requirement on newer generators. This happened to mine; a 2010-2500 and a friends 2013- 3500. Give it a try!

cheer...

A first step is to verify proper function of the LP regulator.........

A few years back my Onan would only stay running if I held the Start button in the start position.
Luckily, still under warranty - dealer removed, found faulty armature winding ?
Dealer said it’s not an uncommon fault.

Although I have different brand of coach, yes, removal was dirty, awkward and difficult. Electric connection inside coach was where he separated the leads to the gen from the coach.

Lots of possible causes of your problem.
