No power to dash

Gotta be a blown fuse. Pull em one at a time and check them. Also a test light comes in handy with the rig running.

My rig has an "IGN' relay that engages 10-15 seconds after engine start. It has a circuit breaker. Both are located in the battery control center.

Blown fuse, that happened to me in Utah.

Afterwards check the load on your cigarette lighter or USB's. Cell phone charging, iPads, back-up cameras etc. Rule of thumb should not be more than 3.

Tiffins have a 100 amp solenoid for the OEM Dash add ons. Odds are the solenoid has stuck OFF. What you can do for a quick test(does not always work) is to rapidly cycle the ON OFF key switch 10 times or so. IF you restore power, that solenoid is bad. It is located either in the LF storage bay, or the bay front or rear of the entry door. Doug

Nope start looking for a bad ground even a rusty one will do it. There are many grounds in that unit but start with battery to frame the enging to frame so forth.

How come people never suggest to look for a loose/bad POSITIVE connection????????????????????????????? Doug

Too many posts saying it is always the ground!

I know, MY pet peeve. after 42 years as a Tech it is RARELY the ground:B Doug

Maybe because the flow of electric is neg to pos if you check his post you will see it has many circuits and a ground cover many. Not like a fuse line a few in line it wouldn't jump all over the system. A ground and cover many and rust and cause a lost of problems.

Conventional current flows from the positive pole (terminal) to the negative pole. ... In a direct current (DC) circuit, current flows in one direction only, and one pole is always negative and the other pole is always positive.
