Took the 76 Palm Beach out for the first time since purchasing it last year! Had to plug into a 30 amp service since the campground did not have a 50 amp service available. House battery was at a full charge and by morning the battery was dead. My question, should the 30 amp service supplied enough amperage for the converter to keep the house battery with a charge?
Also, my refrigerator is ac/dc. It also ran until house battery was drained. Isn't the frig supposed to automatically switch to ac when service is provided?

fridge needs 12v for controls
You should be able to run 30amp with no problem.
Possible the 30amp to 50amp adapter, or connection, not giving power to both sides of the 50 amp

If your refrigerator is ac /dc not ac dc propane it likely drained the batteries overnight running on dc because your Ac pedestal wasn’t suppling 30 amp power as suggested you may have a problem with your adaptor a circuit breaker Turned off to name a few .You should always make sure the ac power is coming into the coach when you plug in.

Very possibly the converter did you verify you had 120 volts in the coach by turning on an ac unit or other appliance. If you did have power in the coach make sure there is 120 volts where the converter plugs in. If there is power there check to see if you have around 14 volts at the converter output if not you likely have a bad converter or a bad converter fuse if there is one. The converter should also have a circuit breaker in the breaker panel

Has 120v to the receptacles. Did not have any fuses blown on the fuse board. All circuit breakers are on and neither has tripped.

If none of the 12V fuses are blown take your trusty multimeter and measure the input to the 12V supply. If it's good, measure the output. If it's good, measure the other end of the output at the 12V fuse block. If it's good find and correct the missing ground. This should be a fairly simple but time consuming fix.

The TT-30P to 14-50R dongle adaptor is a bit of odd kit. You should understand how it is wired so you can test it and have an understanding for future use. There are three prongs on one end and 4 receptacles on the other. The Ground is wired one for one. The neutral is wired one for one. The hot on the TT-30 end is paralleled to both hots on the 14-40R. You can confirm this easily and safety on the bench by using the low Ohms with tone function selected on your meter.

If you can feel or hear the converter and you measure less then 13 volts dc where the converter connects to the dc buss you need to replace the converter.

If you still have the original dumb converter now is the time to replace it with a new progressive smart converter

That should work ok but the pd9245 should be all you should need. I put a +40 in mine many many years ago It was a 40 amp smart charger it had no problem keeping my 2 golf cart batteries and start battery up to snuff

Sam,
Thank You and this is why a lot of us are here. As said, we have an agenda, and that agenda is to see that you get to enjoy both the coach itself and what it can do for you.
