    I have a separate battery for it and would like to connect truck battery through trailer plug to keep sander battery topped off. Can I just connect pos./neg. pins in trailer plug to battery to charge it ? Trying to eliminate me forgetting to put battery charger on it and having battery go dead at 4am in a snow storm :realmad:.

    i had mine hooked to the ground and aux on a 7 pin make sure that the aux is fused, if the battery went dead for some reson it will burn up the wire

    BS, I thought the trailer battery got charged through plug.

    GMD, battery went dead because I didn't charge it. The aux. is fused in the fuse box of truck. All I need to do is get another male plug and run wired to sander. I sure miss my gas sander.

    they do get wired in through the trailer plug. Don't see why this would be a problem? I doubt you'll be towing while sanding?

    OK the real problem was wires that I had put a clip on wire connector that corroded. Ran two new wires with sealed connectors and problem fixed. I may still wire it in through.
