Hi my name is Robert....
Near the battery you should have a house disconnect switch and a chassis disconnect switch, do you have power in and out of the chassis disconnect switch?, if so check all the fuses in that compartment, follow the cable to the breaker box and look for a tripped breaker, that box should be in the front roadside compartment. I might get a test light and follow the path from the battery, through the disconnect to the chassis fuse box check all the fuses and breakers... Robert

I have power on the main leg coming from the rear chassis dissconnect switch in the into a fuse box area to the D/S in front of the wheel there is a printed circuit board which has a bunch of fuses and there are 2 small fuse boxes underneath that I've checked all off them to be good and I back probed the key switch and I have no power there

Try to follow the harness into the dash, look for any plug connectors as well, sometimes they will use a male and female plug that will pug together and carry a bunch of the DC wires. Sometimes they can vibrate loose. Not sure where to look next as if the chassis fuse box has voltage it should be getting to the dash area. IF you like I can put your question back up for others...

if I have power inside that left front fuse box is there any other fusible links in that circuit to the dash cluster

could that printed circuit board have gone bad were it has the engine ignition relay
Expert:  Robert replied 1 year ago.
I would not think there would be any fuses in the dash area...
The printed circuit board could be at fault, is the only thing that is making any kind of sense. Is there a name or model number on that circuit board?
