Water leak and then some

So this year I’m the Bug. Broken shock, house batteries boiling over and flat tires and of course  water leaks. Finally found the leak.  The overflow vent. The check valve is allowing water to slowly back flow into the tank when connected to city water. Eventually the tank over flows. At the top of the over flow it is leaking back into the motorhome soaking the floor and eventually out into the living area, allthough it isn’t happening fast. So we’re done, calling  this trip a wrap and working our way home a month early. All in at about 9,000 miles or so plus 2500 on the jeep  taking on excursions.We’re presently in West Virginia and will make a few stops on the way home but we’re done. Parts take forever to obtain right now so it’s better to be home where the delivery time isn’t important.

That'd be the check valve built into the water pump.  If I were you, I would just replace the whole pump.  They are less than $100.

Yup, not messing with repairs on a 10 year old pump.  I’ll replace it

I am so done with this trip. Now the starter on the generator won’t engage. No way to get to the starter and give it a tap either.   Cant wait to get home and park this thing.

Yowwwie!

Damn!

For what it's worth, I had a similar generator issue way back, about 12 or 13 years ago.

Anyway, I traded that RV in on a new one, I was honest about the generator issue, the dealer said they'd accept my RV in trade if I would be willing to pay up to some dollar amount (I forget the amount, maybe $1,000) and I agreed.

They had to drop the generator to get to the back of it after taking the cover off.   It was a dirty connector to the starter motor.  My memory of the cost was about $300 or so).

Hopefully your fix is something you can do or at least get at without dropping the generator.

I’m going to have to drop the gen.   After market starters are readily available for about $40. Oem is about $110 and not readily available.  Stuff breaks etc. it happens.  Just been a lot on this trip . I have a friend in Tennesse that we’re stopping to see who has a good shop so I could do it there if I can get a starter in time

Here's a link to download the Onan 4000 service manual

Ebay might be a good source for new old stock Onan parts.
If you can't find a Shurflo water pump in stock anywhere try Camping World.

We'll, the bright side may be it could just be the relay.

Guessing here but it’s spinning so it’s either the bendix or the starter gear that’s gone south.

Oh well, I was trying to put a bit of positive spin on it.  Anyway, looking in the service manual for my 2014 Onan, it looks like the hardest part is dropping the Gen cleanly and getting it out from under the RV, (and reverse to put it back).  Putting and reinstalling the starter doesn't look too difficult.

Don, that’s it in a nut shell. Hardest part is dropping the unit. That’s what makes it pretty difficult to do on the road.  When I get home I’ll use a motorcycle lift to lower it. Lots of options for after market starters.  Being it’s a task to lower it I’ll stick with OEM. I’ll be home so I can wait for availability.   I will say I don’t care for being the bug.  Being the windshield is so much better.
