76' Argosy 12 V lights only glow dim. the system was working fine until I changed a bulb and now the bulbs just glow. Checked all the fuse and replaced the bulb I was changing with original and still just an orange glow from the lights. Help, going camping next weekend in Michigan, no 12v so the furnace does not work either. Oh I am pluged into shore power.

Welcome to the forums.
It sounds like the Univolt (converter) is no longer functioning for some reason. To verify, charge the coach battery and check again.

Sounds like it could be a bad ground conection at the light.

Check you have a good connection in the socket. After 3o something years may need surface cleaning.

If you can not find a problem in or around the socket that you changed the bulb in, loose ground connection of the socket, do the following.

Disconnect one leg of the battery and measure the voltage on the battery. This checks the battery. If OK reconnect the battery and disconnect the battery feed to the fuse panel. With the trailer plugged in measure the voltage across the wires from the converter/battery to the panel. This checks the converter. If OK reconnect the battery feed to the panel. Remove all the fuses and as you reinstall them one by one measure the voltage at the panel. When the voltage drops below 12 volts you have located the circuit with the problem.

Howie. Just trying to understand for my situation. I have an Intellipower wired to the fuse panel and the battery is also wired to the fuse panel. If the one leg of the battery I disconnect is the battery feed to the fuse panel can't I both check the battery and the converter without re-connecting and then disconnecting different leads?

What I described is the easiest to isolate things to be sure you are only looking at thinks as they are added to the system.

If you disconnect one leg at the battery and then test you know you are only looking at the battery.

When you reconnect the battery and disconnect the feed wires at the fuse panel you then are only looking at the Intellipower and how if is effecting the battery. If the voltage drops at that point you would know the Intellipower is bad.

As you add fuses and check the voltage the fuse that drops the voltage at the panel feeds has a problem. Possible short in the wiring.

If your problem is only present when the one light is on the this testing may not be necessary because the problem is most likely in that fixture.
