inside lights go out and come back on

[rvjr]

I have a 1998 Winnabago Brave Motorhome, This past weekend the inside lights and frig and ac would go out for 15 to 20 minutes and come back on i was told today it was the power converter them things are about 400.00 dollars what do you all think the problem might be. Also that happened a couple times Saturday and Sunday it never happened

Did you have a lot of lights on saturday and what on sunday was it cooler that day or just the same temp all weekend. The converter/charger is going to be the issue if you don't have a inverter, problem is the fan is not working and it is heating up and cutting off. Also that might mean your house batterys are dead too because you lost everything all at once.

You need better diagnosis. Who did it?? Did they use a voltmeter and did they expand their explanation?

Batteries alone if charged would keep the lights on steady. What is most likely happening is a thermal breaker is tired and shutting off, then cooling, and resetting.

Put a voltmeter across the batteries while plugged in. Turn on a bunch of lights and anything that draws 12 volts such as the heater if you can stand it for a few minutes. If the things go offline you need to be measuring across the battery. If the voltage actually goes up a bit due to lack of load the converter is working fine and as I suggested your output line is opening up. Do a search for 12 volt thermal breakers and you will find some examples.

Where is the Thermal Breaker located. And also my Converter has a loud Buzz to it , Should it do that nobody checked anything this was just phone talk.

Do you have a multi-meter to check voltage. Then need to start taking readings, then make the problem happen again by turning all the lights on. If your batts are good and have charge like said above its a auto CB kicking off. But check voltage with it unplug then check with it plug in.
