    Aren't they hooked together, in series I believe?

    Hook to the one on the Drivers side, install the solenoid underneith the black fender bracket by the firewall, mount it upside down right to the bracket.

    Unless they are 6 volt batteries they are connected in parallel. Trucks do not like to see 24v for some reason. :)

    For parallel batteries it does not matter which battery you connect to. Choosing which requires the shortest cables should be the concern, and the drivers side battery usually works for this like Johnny mentioned.

    Crap, I couldn't remember which it was. I'll try to imprint that on my brain so I do in the future.

    Sorry. :eek:

    How about the P in parallel = "P"low ???

    S in series = "S"crewed up truck?


    :)

    This of course is for 12v batteries.

    Or


    P in parallel = the "P"u**y you will be getting when your truck runs.

    S in series = "S"leeping alone when your truck does not run.

    Just trying to help. :)

    The batteries are factory (Chevy) installed, just wasn't sure which battery gets the power from the plow. The reason I ask is because my former truck (8.1 vortec) had the same factory setup and the plow was on the main battery. As the main battery got worn out over the years the truck wouldn't start even with having a backup battery. However, I would be able to jump the main battery from the aux battery (aux battery always had a full charge) Didn't make too much sense to me.....What was the purpose of a second battery if it didn't pick up the slack of the main??

    Are you sure the old truck did not have an isolator? That would be the only way to describe your issue there.

    Unless there is some isolator that I am not aware of in the 2007 (camper package maybe), the two batteries are connected in parallel and can be treated as one battery. That is, any combination of positive and negative will give you 12 volts.

    Here is a pic of how the batteries are connected in the 2007. Hope it helps.

    Your gas engine had an isolator. Your diesel does not.

    The pic drawn above is correct for what you have now.

    Gm offers 2 Aux battery options. One is 2 batteries in parallel as in the diesels. the other option is the Power pac which puts a solenoid between the 2 batteries. This was used mostly with people wanting Aux power (Like contractors running inverters for power tools).
