12v power for antenna
Anyone have any idea where the fuse is located for the radio switch in the dash? the radio switch for the am-fm when the key is off and the tv antenna power button are dead, no 12 volt power. Checked all the fuses under the dash on the left, checked all the fuses in the coach power center all are good but no idea where the 12 volt power for the radio switch and antenna comes from. Hope someone has some ideas because I'm almost out. HELP!
I have checked the inline fuse behind the radio and have pulled #17 in the block in fact I have pulled all the fuses in the block and checked them also all the fuses in the power center and also in the black box under the hood. I have no idea where the power comes from for that switch which also feeds the antenna power. This has me completely puzzled.

Your radio is normally fed off of the chassis battery(s). You need to check and see if there is any power to the switch on the dash (if you coach is equipped that way) and trace it back to the chassis bus if not.
The TV antenna booster should be powered from the house batteries side. You might want to start at the connections to the TV booster switch itself.

Normally??
In my coach the dash radio is powered by the house batteries, (as is the TV antenna booster)......however, the radio memory is powered by the chassis battery.
There are 2 radio power wires, (and 2 inline fuses), for the radio, (1 for the radio itself and 1 for the radio memory).

Mel,
My coach is a bit newer than yours. Don't know about the OPs coach.

I do have the switch on the dash and it lost power at the same time, I accidently shorted the power wire to the antenna when I was hooking up the power for satellite. The radio is fed off chassis battery when coach is running and you flip the switch when shut down to run it off house battery. Radio plays off chassis but not off house, I will look for the inline fuses but to trace the wires I don't think so because they go into a giant covered harness. How would you trace them without cutting open the harness and most of it you can't see?

Ok, he has a dash radio that likely has a "House/Chassis" switch and he's saying it works on Chassis, key on, but not on house.
It is very likely in your main 12 volt fuse box for the house.. Most motor homes have 2 or more fuse boxes... ONE is exclusively house systems.
The others can be mixed.. On my Damon Intruder I have 4,, One very nice Progressive Dynamics panel with LED's that let me know when a fuse is popped.
One near the parking brake, selected chassis fuses
One top and center under the HOOD, NO MARKINGS AT ALL, all chassis fuses, this is the main chassis box
One Intelletec Battery Control box, to the driver's side of the last one, this has a mix of fuses in it, some are house, some chassis.

If your black box under the hood is labeled "RV Custom Products" FW-2050. Then F-35 is the Radio fuse (5 amp). F-36 is the power antenna fuse (7.5 amp). and F-39 is the radio memory fuse (10 amp).
If the black box is labeled something else then never mind.
You could post the the model number of the black box under your hood in your MH, and maybe someone else on this sight might have the information you need.

My antenna fuse was located behind the tv/cable antenna box in the over-dash storage area. It is an inline fuse tangled up with a bunch of other wires.

Guess I need to clarify my problem, There is a switch on the dash for the radio to work it either from chassis battery or house battery, the antenna picks its 12v up from that also or it just dawned on me it may pick 12v up from antenna so I will look for this fuse. Thank you Bounder30t

Check the fuses under the hood, There could be 2 boxes that have fuses under the hood.
