I will check and see if fuse #30 does indeed kill the 12 volt feed to the 7 pin receptacle, that would be terrific if it does. In the manual it is referred to as the Trailer Tow Receptacle, hopefully it just kills the 12 volt feed and not the other functions.
Thanks for that tip, should have thought of it earlier. That is why i LOVE this forum!

In the Ram trucks there's a fuse in the engine compartment that u can pull to disconnect the hot wire, I think it is #30

So how to test the Ram? Could I just use my VOM or a 12VDC test light to see if the 7 pin plug battery charge terminal is hot with the ignition off?

I wouldn't give up the ability to charge underway even if you have to put a switch in to make it only available when needed. I guess it depends on the truck and how much you discharge the batteries, but my truck charges my batteries pretty well and my TC doesn't discharge my truck batteries.

When I look at the 7 pin wiring diagram, if I disconnect the 12 volt feed wire from either the umbilical cord or the truck receptacle that should isolate the batteries.
Are you sure it is "hot at all times" ?egarant wrote:
Of course I will not be able to charge the house batteries when underway, but I have full solar for the purpose.
You are probably not doing a good job charging you house battery anyway. There is quite a lit of wire from the fuse box to your house battery and a couple of connectors. This all adds up to voltage drop. meaning even when you are driving down the road, you are likely NOT getting enough voltage to properly charge the battery.
Go ahead and disconnect it.
If you really want to charge you house battery while you are driving, get a DC input battery charger (YES, they do exist; typically will accept 10V input) OR run a 1000W sine wave inverter directly off of the vehicle battery with very short 4 gauge or even 2 gauge wire and plug it into your converter/charger. A 500W inverter would run a battery maintainer and you could drop down to 10 gauge wire.
