Everything works when the engine runs so does it charge the house batteries also? I have 2 trojan 12v wheelchair batteries and 2 other brand 12v
wheelchair batteries wired up for 12v but they dont last very long. Onan still not working. Full time in Arkansas :d
 
Aaron,
What year and model is your coach?

It would also help if you had a signature line at the bottom that included that information and at least the state that you located in.

Aaron,

What year and model coach?
It was supposed to....
It sounds a lot like something is wrong.
Do you have a meter?
Do you see changing voltage when the main engine is running?
Have you checked out the isolator?

You say you have two pair of 12V deep cycles?
Two back by the Onan and where are the other two?
This is an unusual installation, you will need to tell us a lot more about it.
I hate to tell you this, but Lead/Acids do not play nicely in parallel. You will never get full capacity out of them.

Your Onan "still" does not run....
What doesn't it do?
Does it make noise but not electricity?
Does it crank but not fire up?
Does it not crank at all?

You have been here a while, and this is a very supportive and helping community. It will help to help you better if you fill in a sigfile with a real
name because we like to know we have met when we do meet. A short bit about the coach like year, model and including major mods. A geographic
location would be nice, but I did remember that you are full-timing. That may be a little difficult, but if you listed when you are at the top when
you write, then if there is someone in striking range that can help, he mike be motivated to do so.

Sorry

In Hardy AR for now.

Yes it does charge my batteries in the back. I have all 4 there. Now I'm out of gas though. Lmao.
 
there are many different things that can deplete your batteries, or allow them to charge.

best thing is to have a good 3 stage converter, and use 110v power run that to charge batteries. Even a super small generator will power the
converter to effectively charge the batteries up. you need to see about how the different banks are hooked up to make sure it is charging
everything. the engine running will charge the batteries off the alternator, but that will be a slower process in most cases due to alternator
size, and probably the wiring sizes to the battery banks.

There are so many variables to the different batteries, and wiring that people do to these coaches to even to begin. I have found time and money is
best spent on conserving electricity, rather then finding ways to store it and generate it.

Great article. I remember it, and until Ohm’s law is repealed, its remains the gold standard.
