Inverter problem?

I am having some type of electrical problem that I am not quite sure what it might be. There are times even when hooked up to 30amp shore power my lights and other items act as if I am on battery and the batteries are very low. Then usually for some unknown reason it gets better. Also on a recent trip out west even after pulling the trailer for hours when we should have a full charge on our batteries it is as if they have not charged. I have installed new batteries so I assume this should not be the problem. This is on a 2007 25' Safari. Any ideas would be greatly appreciated.
Thanks in advance,
Greg

Check the connections at the battery and the ground lead. Sounds like a poor or intermitant connection

Assuming you mean 'converter' instead of 'Inverter'...here's a couple of ideas...

1. with converter turned OFF, or shore power unplugged - measure the voltage at the battery terminals.

2. now plug into shore power (or turn the converter ON) and again check the voltage at the battery terminals - you should see a RISE in the voltage if the converter is working.

To check battery charging while towing...

1. check the TV's fuse panel to make sure you haven't blown the fuse that protects the 'charging' wire in the towing harness...check the owner's manual, it usually indicates where the fuses are located for 'towing equipped' vehicles.

1a. also check the fuses in the AS's fuse panel to be sure all is well there.

2. again, you can check the voltage at the battery terminals, with the 7-way cord unplugged from the TV.

3. now plug in the 7-way cord, start the engine on the TV and again check the voltage at the battery terminals - you should see a rise in the voltage if the TV's alternator circuit is connected properly through the towing harness, 7-way cord, trailer fuse panel, and to the battery...you may have to run the engine at a high idle to see the voltage rise...

3a. if you don't get a voltage rise at the battery terminals, you can 'backtrack' each of these items with your voltmeter to see where the problem is...

Hope that helps....

Ray

Ray,
Thanks for the detailed plan for troubleshooting! I will try to work thru that today.
