What should all fuses make test light?
If the ignition switch is ON but the engine is not running, all the fuses should read about 12V or the test light should glow. The switch to turn things on is downstream of the battery and the fuse. Tail lights should be connected around the ignition switch directly to the battery so they can be turned on without the ignition being on.
Are there no lights and now power at the fuse box?
No lights no horn and now now power at the fuse box. I am in trouble now did not want or need an electrical problem.
Why does my test light not light up?
Looking at the fuse itself, it is not blown. Just trying to understand if this means there is definitely an issue in the circuit of it’s normal for light not to light up. If the ignition switch is ON but the engine is not running, all the fuses should read about 12V or the test light should glow.
How can I tell if my fuses are still working?
The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate. Check a few of these other systems to see if they operate or if it’s isolated to the radio and dome lamps.

Why are the lights not working on my coach?
Sounds like a possible transfer switch or fuse issue. With the 12 volt lights working when on shore power means the charger is working. Look for a large fuse between the batteries and the charger 12 volt output feed to the positive coach battery terminal (s). With a meter you should read a voltage at the positive terminals.
Can a fuse have power on both sides?
You can have power on both sides of the fuse, yet not have it conduct power to the circuits if there’s a spread terminal contact on the circuit side of the connection (just had one on an Intrepid).
