I have a 1992 Pace Arrow 37J. Chevrolet 454. Bought a new chassis battery and connected it the same as the previous one (so I thought). I had nothing no coach, no chassis. Went back to check, and one of the posts on one of my coach batteries had melted the solder for the connection. Got a new part, fixed the coach connection, swapped the battery cable the the other way. The new battery connections were swapped from the previous one. (Everyone make sure you check). I now have coach power, lights, step, fans, but no chassis power to dash at all. I Checked the battery with multimeter. It is still ok. Checked fuses in box, all ok. It seems like there must be some kind of master fuse or circuit breaker. Can someone help? Thanks!

I'm assuming you are swapped the house battery and not the ignition battery.I'm trying to recall anything in the dash that runs off the house battery and I'm no making it, every MH I can recall the dash runs off the ignition battery.

Maybe battery isolator......should be in a battery compartment. Can be analog (round) or solid state (pictured).

There is a fuse link down by the starter. It connects onto the battery terminal of the starter and feeds the fuse block under the dash. Fuse block under the dash is to the right of the steering column. Awkward to get to unless you have a driver's door. There is a main fuse on the fuse block. Should be marked "IGN" on some.

Connected chassis battery wrong, no power to chassis

It is the chassis battery. It is the one that runs the coach.

OP needs to check for power on the wire coming from the fuse link. No power there, then check the fuse link.
It is almost impossible on my rig to get to because of the heat shield around the starter and the knock sensor being right there.

Great. I will have to try that. Any idea as to what it looks like? I do have a drivers door and I have checked all the fuses. I will see if I can find the IGN fuse. Any idea as to what amp it would be?

Thanks!

I was afraid you would say that. The isolator is smack dab on the fire wall. The only problem is, they ran all the major cables over it and through the firewall. I don't think I can move them enough to get to.

Why, with as much room as there is in the compartment do that smoosh everything together?

Thanks! I will see if I can loosen the cables enough to remove it.

My is in the upper right corner. It is a green metal cased looks more like circuit breaker then a fuse.
To the lefty of the above fuse location, is or on mine is a large red wire going to "IGN" terminal make sure it is hot.

This is what I see. You think it could be either?
