Charging house battery

[Pez]

Will towing my 5th wheel charge the house battery?

Welcome to the forum

Yes it will as long as the “charge line” is enabled. Depending on Tow vehicle, there may be a fuse or relay or both that need to be installed.

Easy way to know is with a volt/ohm meter. Plug into the tow vehicle and start the engine. Measure the voltage at the trailer battery, anything over 13VDC and it’s charging.

Great reply Chuck!

To be honest, I just assumed that my truck was charging my batteries, but I will now do the volt meter to find out.

Thanks!
