Dash Radio

Roy....if it's a Magnadyne which Monaco used a lot, there is a fuse at the back of the radio. Even if it's not, most radios have a fuse in line behind the radio or even mounted in a holder at the back of the radio.

You should have 2 separate 12 volt systems, one for the coach and one for the chassis. The dash radio should be on the chassis system. In my gas coach, the fuses are under the hood, in front. They're inside a box that you will know. It's labeled or should be.

Or the radio just crapped out hahaha. I read this because I just bought a new head unit for our coach. They 2003 stereo doesn't have any input accommodation and we'd like to have that.

Check to see if the dash fans have power. When my radio went out, other items lost power as well. The 12v solenoid in the back was faulty and caused the problem.
