I had the transfer switch replaced as the unit would not switch to land power from gen power. Also had a electrical short from a engine heater plug running from an outlet just behind the transfer switch. The short made a racket and activated the breaker switch so a first it seemed like the transfer switch. The sticking switch caused the generator to stop running also.

Now I am running the unit on shore power and it still had a problem switching over. I was on Generator, then went to shore power and the air con units continued to run, but the house 120v did not operate UNTIL I switched on the inverter, which caused the house circuits to work. Then I shut the inverter off and the power stayed on just fine?

I am going back to camping world and ask them to recheck. I have other electrical issues with this unit.

Tom, can you help us out by letting us know what coach you have, year and such?

There are a lot of variables that must be known to figure out what needs to be addressed first. The make and model of the transfer switch would also be handy.

One thing that comes to mind is that the transfer switch I installed my coach has a overide feature, giving the generator priority over shore power. There is also a delay before the switch will transfer power to the coach after starting the generator, this is allow the engine on the generator to briefly warm up. The sort of this is if the generator is running, pluggin up the coach will make no difference.
If you can, you may want to make sure the transfer switch is wired correctly.
A model number would be required to help with this since there are more than a couple transfer switches, and several ways of making it work.

Tom's coach is this '98 38' Monarch

I think I have this solved. Not 100% sure yet, but three of the 4 coach batteries were dry, which may have been affecting the electronics. I have played with shore power, generator power and inverter power and it seems to work now that I filled the batteries up. They batteries that were empty, each cell took about a pint to fill it up. Are now warm to the touch the fourth battery that was full is cool to the touch. Checking cel to cel voltage would be a good way to check the battery condition.

I had not checked/topped up our house batteries since returning from AZ in the spring.
After a number of outings this summer and fall, mostly boondocking and on genny but with a plug in only for a day or so when when we get home; I was surprised to find that both our house batts were very low.
When sitting at home for any length of time I always throw the master switch to kill all power to the coach.
So ... moral is: gotta keep a closer eye on those house batteries even though when living in the coach all winter, plugged in, I can't recall ever finding low acid levels.
Wonder what changed? ... Maybe because of a different type/level of usage, not being plugged in most of the time?
Like all of us, Tom, looks like you have a number of bugs to iron out with your new coach. It's been only a year and a half for us, and once you get past all this you will be amazed at how good your Barth is compared to the other stuff out there.
BTW, from the pictures, your coach has a real WOW factor!!

I second the notion that batteries MUST be watched. I have an auto fill system on my golf cart house batteries and on a 30 day trip with constant batteries use, both charging and discharging. I will go thru well over a pint of distilled water.

Batteries replaced and the transfer switch worked with shore power, it did not before it was changed. But would work with generator power only some times and then off batteries all the time.

The camping world tech took the inverter out and found a loose connection on one of the leads. That was tightened and all seems well now. The batteries have been holding charge for several days now with light use. Yea!

However the batteries for the coach were 24 series 12 volt standard units. I had a bad situation and was looking for a replacement set. Autozone was the only place local that would help me put the batteries into the coach.

31 size for the Engine well and good.

I wanted 24 Deep cycle but they would not fit the battery trays in the coach, original I am sure.

The only battery that would fit was the standard size 24 12V. I put them in anyway and they come with a 3 year full replacement and 8 year warranty.

So with storing them each year for 8 months that may be good.

But why did Barth use 12 volt standard for the chassis?

As to the transfer relay, relaxed -i.e., default, is the generator; if the relay is bad, it won't close to send shore power to the converter/inverter. Jeff ran the generator and that's the only thing I was able to test; the inverter took over when the genset was shut down. But it sounds like the core issue was solved, that of the transfer relay.

At the age of your coach, I'd suspect that the batteries you encountered aren't the original, especially if the coach lived in Florida. Someone replaced the OEM with others.

I like 6V golf cart batteries (which is what I have in my coach) wired in series. They're very durable, and can stand abuses common "deep-cycle" batteries can't. They may require hold-down mods - they're generally taller than the stock sets.

Anyway, Series 24 batteries are all basically the same dimensions; if you were told 24 Deep-Cycle wouldn't fit, I'd be skeptical. Storing cold on standard 12V non-deep cycle batteries isn't a good idea; keeping 120VAC power to the coach is. That'll keepthe batteries topped off (electrically - but an arrangement to check electrolyte levees has to be arranged).

I had the pleasure of meeting Tom Loughney today; with regards to all group 24 batteries being the same physical size, they aren't - Tom and a store manager tried the G24 deep cycle, and they wouldn't fit the trays...
