battery isolator on a adventurer 37g

[srt20]

Where is the battery isolator located? I cant seem to find it. My alternator doesnt charge my house batteries, and the boost button on the dash doesnt work either. Im assuming that if the house batteries die, you can use the battery boost button to start the genny, right?

Anyway, this is my first MH, and I got it last year, but was plugged in every time we used it but once. And that one time, it just happened to be cold and the furnace died halfway through the night..... Then I had to use jumper cables to jump start the house batteries of the chassis battery. I also discovered the PO used small car batteries for house batteries.....

Anyway, and advice would be GREATLY appreciated!

The battery boost button ties the coach and chasis batteries together. Typically its to boost the chasis battery from the coach not the other way around. The solinoid is most likely located under the steps behind a panel. The panel is usually identified by a label. If the batteries died thru the night, I suspect the batteries are bad and need to be replaced. I had the same problem with my PO and all 3 batteries were bad and had to be replaced; some people?

Ok I found the isolator. Thanks. I tested the isolator and I have power on both the chassis battery side and the house battery side. But no juice to the little wire in front which should be the power to the isolator from the ignition. No juice with key off, or key on or key on engine running. So maybe Im looking at a blown fuse? Ive looked in the Ford chassis manual, but it is no help as to trying to find where the fuse is located. Any help on that one?

So what your saying is the battery boost switch works only one way? It boosts the chassis battery from the house, but it will not boost house from the chassis? That stinks, kind of a dumb design, unless Im missing something.
Yeah, I plan on replacing all the batteries, but I want to get this system working properly before I do.
Thank for the help!

It ties the 2 sets of batteries together. It works both ways. When pushed and held you have all 3 batteries in parallel.

I guessing but I think the fuse from ignition to the isolator solenoid coil is a 5 amp.
