I have a question about using the alternator to charge house batteries while driving or running the engine. I have a 2004 renegade with the Mercedes 450/12spd. I am wanting to run a jumper wire from my truck batteries to the house batteries.,I am wanting to hook it to a switch so it can be shut off. I think it would be handy to have if you ran down the house batteries, you could use it to start the generator or vice versa to jump off the truck if e truck batteries get weak.

I have a master shut off switch for the truck batteries just inside the door under the driver seat and would mount another just like it for between the truck and house batteries. Do you think the alternator could handle this? I would use 1/0 wire to handle the load.

Thanks
Eric
