no 12v. system after unplugging from AC line

28' 1995 Warrior. electrically all was well with the truck battery and automotive electrics and the house batteries (new deep cycle installed in June). Suddenly when I unplug from an 120 V. AC outlet there is no 12V. system working at all. I have tested the coach batteries and they are fully charged. There must be a breaker that is tripped but where is it?

If you've got a battery disconnect switch (AKA Salesman Switch) check that first, it could simply be turned off. If it's turned on make sure that the power is actually getting through the solenoid that the switch controls.

If that's not it, there should be a main fuse mounted somewhere not far from the battery in the positive cable. Follow the cable from the battery, I wouldn't expect it to be more than a couple of feet from the battery, probably mounted to the nearest wall/bulkhead.

Several differences in US and Canandian versions on this one but some key points we might ask about.
Do you know about a fuse group under the rear dinette seat? Seems to be one to check.
Also if power is not getting to that, the "battery mode solenoid" shows located on "right front frame rail" which means to me that it is on the main beam of the frame.
One big one to be aware of on used coaches is that many people do mod the wiring and it sounds like there may be a switch to disconnect the batteries like when stored to avoid paracitic drains like clocks from draining the batteries. Those mods can be found in weird places and not on the drawings.
Good luck??
