12 volt electrical problem

My 12 volt fuse panel went out with no power. The main input black wire has no power. When we connected the panel directly to the battery, it work normally. It appears the main input black power wire is broken, interrupted or something else. Since the wire goes into the floor next to the inverter and behind the right wheel well, we cannot see the path. Has anyone experienced the same problem and do you know the path of this main power black wire from the 12 volt fuse box to the battery. Until I know the path, I do not want to bypass.

Thank you,

Caesar, according to my 2003 manual the "12V House Fuse Block" is wired directly to the House Disconnect Switch (I'm assuming you know where that switch is located.). Even though your MH is older I would only expect the fuse block location to be different.

Oh, forgot to mention that my diagram shows a 50A fuse between the disconnect switch and the fuse block using a "black" #6 cable. It doesn't state where that fuse is located but I would trace cables coming off the disconnect switch to see if the fuse is on the firewall. If not, then I would expect it to be close to the fuse block.

On a 1999 36SDS model there are 2 disconnects; the "Chassis" battery disconnect is in the rear service bay and the "House" battery disconnect is in the entry step well to the right (front wall). I don't know where the "House" battery disconnect is on an FDS model.
Regardless, flip both on & off a few times and then check power when they are in both positions.

Another thing you can check are the connectons at the isolator, which is high on the rear bulkhead of the battery bay.

Also, there are some wires above the batteries that have in-line fuses. Check inside the split-sleeve plastic wire covers for them (WRV did a good job hiding them and they are not quality items - I had to replace them on mine).

Thank you. Sounds like the in-line to me.

Caesar- if you don't have the chassis electric schematics for your coach, send me a PM for details. I have reduced copies, 18"x24" with all the circuits. This also doesn't tell you the routing, but it tells you what is connected to what which helps to find the other end of a circuit.

PM stands for Private Message. To send one to Mike you would click on his red EngineerMike in his avatar section and one of the options is to send a private message.
