No 12 volt lights ?

2014 Bighorn 3755fl had trouble with converter last fall , replaced converter , 110 works fine , no interior lighting on 12 volt ? Checked fuses , all good

Your converter has three fuse on it, check them.
Also make sure your battery cutoff switch is turned on.

Peace
Dave

Also, there is a 50 AMP circuit breaker between your converter and the batteries. It is on the wall in your generator compartment. The breaker has a tiny reset button on one end. Check it first before checking anything else.

How about other 12V stuff like furnace, pump, slides, etc?

Glad we could help and hoped it saved you a lot of troubleshooting. This is a pretty common problem. It is a good idea to carry a couple of spares of this one, because sometimes they seem to get weaker and blow more frequently. Normally, if I have to reset it a couple of times, I just replace it.

If your lighting problem was happening while plugged into shore power, resetting that little breaker may not have completely fixed the problem. Resetting the breaker would have restored the electrical path from battery to lights. But when plugged into shore power, you should have lights, even with that breaker tripped.

So you may have a problem with the Converter. You can test this easily by switching the battery cutoff switch(es) to OFF while plugged into shore power. If no lights, you have no output from the Converter.

If you do have a Converter problem, and don't correct it, within one or two days your battery will be depleted.

You can also meter the batteries to see if they are charging . . . should be around 13.2 Volts. If you are not under warranty and have to buy a converter, check the price on Amazon. It was a little cheaper than Progressive and Heartland parts.
