The other day I started the coach as the batteries were low and let it run for about 15 minutes. I also Reset the a/c out 1 and 2 on the inverter and when I checked the bathroom lights, they came on.

Since you apparently 'fixed' it once, your issue seems to be easier to decipher. It would appear resetting the inverter, (if I read your post correctly) fixed it the first time. Check those and see if they need to be reset again. If so, you'll need to find out why they are tripping. First place I'd look would be at your friends' pedestal. Many people, electricians as well, don't understand or use the correct equipment when installing RV pedestals in their homes. The suggestion of running off your generator is good advice. Your batteries need to be fully charged also....Dennis

Turning on the generator has given me back the missing power, so do you think the transfer switch is failing. We are in a rest area 150 miles from the New Mexico border and heading home.

bad or possibly loose or corroded connections. that would certainly explain the power loss.

Forgot about this true story.... When I was "Stuck" in GA for a while I made a few friends. One of them knocked on my door to tell me his neighbor had no electric in half his coach (His was wired so L-1 fed one side L-2 the other) As we walked back to the problem coach I ask if he had an INVERTER.. he did not know.

He unlocked a compartment. the battery bay.. So I had him unlock the one next to it. Sure enough there was a very nice inverter (Tripp-Lite) and one of the breakers was TRIPPED.. I reset. he went inside and his wife ask "Does he think he can help" the husband said "He's already fixed it" and so I had.

NO as for the Propane... Can't help you there.


Home is where I park it.

The cord plug is another likely candidate for failure.

The best way to know is to check the voltages and isolate the problem.

Stop by a CG and plug in. Unless you're unlucky enough to find two pedestals that are bad, you'll know if the issue is in your rig or your friends pedestal. In answer to your question, yes, transfer switches can go bad although rarely. Easy to check but you have to know what you're doing...Dennis

I'll amend that statement as it's second best.

The best solution is to use a EMS like the PI HW50C. With it's display you can check the incoming voltage, amps, etc.

But most important IMHO is that a open or partially open 50A neutral can/will cause high smoke letting out damage to the electrical devices. The HW50C checks and doesn't connect and checks and disconnects when a problem is detected.

Every 50A RV should have one. I also had one experience with 160V on a 30A pedestal that occurred at night. RV power was shut off and I ran to the pedestal to unplug.

I think it might be the 30/50 adapter. Check voltage on the main 50 amp breakers in the main panel. Post the results.

I have read about a propane detector that may cut off propane and may need power applied to get the propane moving. Check and post the battery voltage while you are poking around. If battery voltage is good check for 12 volt power at the 12v distribution panel to verify the stack of fuses are same as battery voltage.

Made it home safely, when I got to where we needed the heater, I found a wire hanging off the propane tank that apparently went to the gauge panel to tell me how full the tank is. Got home and plugged coach back in to my 110 plug and all seems to be working now. Will have to check the power connection next trip to Texas.
