I need help finding a 90A breaker or what ever it is called. On drawing # b-2126 it just shows a round circle with 2 wires. One wire is #430 large red wire that goes to my in Ignition solenoid. The other drawing I have is b-2099. I have no power to head lights, ignition solenoid, ignition switch. On one drawing it shows that the 430 wire goes to the isolator on terminal 4. I checked it and it has 12v on it. I drove the MH the other day to fill with propane. Drove fine with no problems until this morning when I tried to start the engine. Generator starts and works fine. Both sets of batteries are charged and up.

Pat,
That may be the resettable one. Look on the backside of the wall it is mounted on and see if there is a hole in the wall. Look and see if there is a button inside that hole. Push same and see if you are back in business.

IIRC, it is in the rear-most compartment on the passenger side. Behind the fiberglass cover on the forward wall.
On our U280 the 12V panel is in the big center storage bay, aft wall, driver side. White fiberglass cover. Remove cover and the 3 round black things at the top are the 90A circuit breakers.
On our coach, the one on the LEFT is feeding the ignition solenoid. This is an auto reset breaker.
On our coach, the one in the middle is the manual reset breaker, with hole in the wall behind it to access the reset button.
I found a breaker on my isolation board. One wire comes from the forth(4) terminal. I have checked with a test light and the forth terminal has voltage and the breaker has voltage on both terminals. I am lost now. I wonder if after the breaker the wire also goes some where before it get to the ignition solenoid ,
Thanks Mike, Chuck, Dave for the help.

Update:
I found the panel Chuck spoke about. Mine is on the forward wall of the bay just in front of the passenger rear wheels. No problem with the panel. I have power on all breakers. So I lowered the cover on the wire tunnel in the other bays going forward. I looked at the red wires(4ga ones) going forward. At the rear wall of the front bay(fuel & propane), I found that a rat had chewed the #430 wire into. I have ordered/bought 2' of 4ga red wire($7), 4 copper butt splices($17), HF lug crimp tool($80). I have doubled checked the fix with jumper cable from 90amp breaker to end of cut wire going to dash. Its all good, everything works.

Rats are nasty destructive little curs. We had one get into our coach through the propane bay. Caused considerable damage. If you have the open vent opening in the floor of your propane bay, I suggest you make a "rat proof" cover. I used some expanded metal mesh (available at Lowes/HD) cut to size, painted white, and secured with screws. One less possible RAT entry point!
