battery not charging while driving

When I was trying to find a draw I pulled a fuse from under the stairs.

This fuse's circuit when in was using ~ 2 amps.

So I pulled it.

However this is the fuse to the isolator, so with it pulled it won't allow charging of the house batteries from the alternator.

The other problem is that with the fuse in and I turn off the MH power it swithched to using the chassis battery to power my MH.

Can't have that happen, so as I said I pulled it.

Bottom line is I have something wrong with the isolator because it causes a draw and allows the chassis battery to power MH 12 volt system.

My draws, propane sniffer, refrigerator on dc, smokedector ?? .. the brain is dim .. seems like I had 2.3 -2.5 amps draw on dc and decided I needed solar for dry camping. I doubt you have an isolator problem .. all it is is a starter solenoid. check the draw on the refrig & sniffer. you need a way to charge, to exceed the 2+ amp draw, when not plugged in or running.

Which fuses are you referring to? FRG mounted my power unit upside down, the isolators are on the RH side.

There are two isolators .. the top on mine is the chassis store .. the bottom is for the by-pass start .. according to the labels on my isolators.

I pulled all of my fuses and they all check good.. my fuse container .. has written on it #5 fuse is alternator, counting from bottom up. #5 & #6 are the only 5 amp fuses ..

Good hunting!

I Error-ed .. My refrig is only Propane & AC, the refrig draw was on propane.
