Comverter Problem

I am connected to shore power and yet none of the 12v lights are turning on. Power is going into the unit as my microwave panel lights up when I connected. We had a power storm and wondered if i have a blown converter? Fuses seem ok.

The converter is on a separate breaker in the AC power panel; reset all your AC breakers by turning them off and back on.

Is your USE/STORE switch in the USE position? Cycle it to be sure; a surge may have switched it to STORE.

If the lights aren't working you may have two problems - dead batteries and a dead converter. Get a simple voltmeter and check the battery voltage at the batteries.

Some converters plug into an outlet in the wall nearby. Check to make sure yours hasn't come unplugged. Some converters have fuses mounted on the converter chassis, not the DC fuse panel. Check your to see what you have.

If you don’t have a surge protector this is a good reason to get one. I have an EMS system, which is great since it will save yourself issues due to bad wiring.

Your 12 volt light should still work on shore power however.

Suggestion: Go out to the outside power pole and also reset the breaker at the pole if you have a 50 AMP. I had a situation with my 50 AMP where I wasn’t getting power to one end of the trailer. Sure enough my EMS said I was dead on one of the poles. Reset the breaker and everything worked.

Converter has been off or out long enough to run down batteries. Frig won’t run. Probably furnace and WH. Converter is either turned off or fried. Led lights do not let you know by getting dim. AW’s list should cover it.

My neighbors had this problem on a fairly new Tommy Bahamas trim and they hooked up and took it to a RV dealer and it was working fine when they got there. And worked for the rest of a long trip. If the found the trouble they were not telling. My unit is so old that I can trouble shoot it.
