2019 26B, My starting toggle switch inside only rocks one way (to start)! How do I prime from inside? Onan 4000

How do you stop it if the switch only rocks one way?

That's the question!

Yes but I can't figure out how on the Android app!

Ah ha found it!

Just a thought, but have you load tested the starter?
If it cranks slow on full charged batteries you could have a starter going bad and "dragging"

I've already pulled the batteries, took them to Wal-Mart and they tested them and said they were too low to load test. Took them back home and put them on the charger and they are holding 12.77 volts. Will take them back and see how the load test goes. Thanks for your suggestion.

I didn't know the engine alternator would charge the house batteries. Is this true?

I guess it depends on your rig. Mine has a Trombetta relay ( I think also called a BIRD) that connects the chassis and house 12V systems together. When the engine has been running for 2 minutes, the relay is fired and a solenoid connects the 2 systems together. That way the engine alternator charges your house system. It also works in reverse so that shore power will charge your chassis battery. It also is the way your auxiliary start switch works, useful if your chassis battery dies. My relay went bad last year. Once I replaced it the system works well. I verified operation with my volt meter, so yes, my alternator does charge my house batteries on my Palazzo. Nice feature, wonder who thought of it?

Thanks for all your tips I was afraid I would flood it if I primed it too much. to the person who thought it was too hard to prime all you have to do is press the start-stop switch in the stop position before you try and start it.

No, it is just "hard" for me to be that patient...(I still only get to around 20 seconds then have to try and start it):coolsmiley:

If your batteries are 12.77 bolts after a recharge I believe they are marginal
at best. It has been my experience that a fully charged battery should have a surface charge of over 12.8 ( the surface charge of a battery is the charge it holds before ANY load has been placed on it) Back in the olden days when cars still had carbs & a set of points they taught us to charge a battery check the voltage then turn on the headlights for about a minute and check voltage again. The headlights pulled the surface charge off the battery & it should read a minimum of 12.8 to be considered ok to leave in the car. A lot has changed since my days at 1970’s era dealerships but flooded batteries technology is still pretty much same.
After 5 years of use in a motorhome I wouldn’t mess around putting them back in even if they did load test out ok. If you plan zero boon docking then they might suffice but I wouldn’t waste the time & effort to put them back in. 5 year old batteries are running on borrowed time

I am a retired mechanic, the following is a volt to charge state we used for years .... note reading should happen after no load for 20 so minutes.

13.8 charging
12.70 100%
12.58 90%
12.48 80%
12.36 70%
12.28 60%
12.20 50%
12.12 40%
12.04 30%
11.98 20%
11.94 10%
>11.90 fully discharged
