Frantic in Kerrville

[Charles Spera]

I sure could use some help!
We are at Buckhorn and went to visit friends in San Angelo for a couple of days and left the coach on its own. Upon return after 36 hours we found the generator running and the gauges show full voltage on line #2 and 0 volts on line #1. I have no power to the refrig, forward outlets. The Hearts show one shut down (how do you restart it?) and the other seems normal but hard for me to evaluate.
I have checked the power at the post and it is wired correctly and delivering 125 volts on each leg. Problem seems like it is in the coach.
The manuals tell me to look in the "110 volt panel". Don't know where that is, doh.
Any help would be most appreciated; hate to think what will happen to the provisions in the refrig....

Chuck, Somewhere in the Bus you have to have a circuit breaker panel just like the one in your house. Find it and start there. Check to see which breaker has tripped. That has to be the starting point. Tell us what you find and I'm sure you will get all the help you need on this forum.

Chuck,

I'm only 1 year difference than yours. Your 110 volt panel is the one in your galley that has all the breakers and switches. There is a breaker for inverter number 1 and 2. Assuming the breaker isn't tripped and you don't know how to reset the inverters, you can unplug from shore power, shut gen off and throw the inverter master switch that is in the 2nd bay drivers side with your inverters and that will shut off all battery power to the inverters. Then plug in the shore power, turn the master back on and see if that brings your dead inverter back to life.

You will not get 110 v power back to the circuit for your fridge, outlets or other sources on that leg without the inverter. It flows through and without a by-pass switch, you will be without power.

I don't have Heart inverters, so I can't tell you how to reset them without removing all power as I suggested above. It should be a simple matter of turning the inverters off and then back on with the remotes or manually at the inverters.

By the way, there is no way to get to the power supply for your fridge without removing it. There is a way to rig up an alternate power source that I can help you with after you get through your present problem, but it involves a one time removal of the fridge.

Bruce,
Thanks for the prompt reply.
The breaker panel is right in the kitchen area and easy to access. None of the breakers were tripped but just to be safe, I cycled them. Still no power to the front 110 volt circuits which upon inventory include the microwave, refrigerator, wall outlets and TV. I have had to move my laptop to the bathroom for power and now communicate while sitting on the toilet with the laptop balanced on the countertop (nice visual, eh?)
Wish I had stopped in for the Oysterfest, perhaps this would have happened there and Truk would instantly analyze and cure it....
I still have it in my head that somehow one side of the 220 line has disconnected inside the coach. Pedestal is still reading OK.
Must be something simple, but what?

If you can find the inverters, look at them for a reset button or switch. I have had to reset one of mine when I had somewhat similar issues. Mine is a Trace, but it could be a similar fix.

Chuck, here is a picture of my panel, it is in the kitchen area. Look to see if a breaker has tripped, also turn the on, off switch on the meter panel, the right hand one is just above the word coach, to off and wait a long moment and turn on to see if it resets. There are two of these switches, one for each inverter.
I could not rotate the picture to proper viewing position, but I think you get the idea. The absence of a cooling fan in the inverter can cause it to shut down when the inverter gets too hot. After it cools down it should run until it gets hot again.

Here is a better view of the on off switches.

[Charles Spera]

Thanks Guys,
I tried the on/off remote switch with a 60 second delay...no joy.
I can see my invertors in the belly compartment and if I make myself real skinny I can reach the reset switch and flip it...no joy.
I tried the remove the shoreline, shut off generator, throw main battery/invertor switch and got a momentary operation when the battery/invertor was turned back on and before the shore line was re-attached, then back to square one...no joy.

Nuts!

[JIM CHALOUPKA]

Are the wires attached properly in the plug?

Pull the plug out of the receptacle and if it is a Hubble brand or similar, not molded on, you can disassemble it and check the connections.

Start at the plug and work your way to the inverters.

Some have had trouble at the inside end of the shore cord where it is connected to the bus.

If you have a spare cord, plug it into the bus in the bay. That would proof out your shore cord.

I would doubt the problem is in the electrical cord. In your original post you stated the generator was running when you returned to the bus. Your problem seems to be both on gen power and shore power. That being true I would check items that are inline to both of these power supplies.
