Dual battery question

    I got my secondary battery tray installed on my 99 Chevy 2500 (6.0L) today. After doing some measurements, I noticed that with the brace above the tray, and with and other parts of the tray, that the only size battery that I could fit in there was 10" long, 7" wide, and 6" high. I looked and there is only one battery that I found that would fit in there and it was not very big. Am I supposed to remove the cross member, or is there something I'm missing here?

    Yes, that brace gets removed (it's not there on the diesels). I even cut the sheet metal tab that the brace bolts to coming off the firewall.

    See THIS link.

    Also, a standard (whats on the other side) group 34/78 is the size you need.

    TLS, thanx for the reply and the link, it was really helpful. Here is my only question, which may sound stupid, but I'm not much of a wrencher and just don't want to mess anything up. You went from the aux. battery to the drivers side solenoid and not to the primary battery? Where did you go with the ground from the aux. batter? Thanx again.

    No, look close....the wires get hidden from the camera a bit.. It's + to + and - to - and a ground from the aux direct to the passenger side head.

    So you are going from battery to battery then. How did you connect the two wires coming together on the primary battery? Do they splice to one connector?

    YES.

    Here is how I did it on a similar pic only on the other battery.[​IMG]

    No problem. Glad to help.

    Just a FYI.... your truck....technically isn't a HD.

    It was a K-2500

    The term "HD" didn't start until 2001 with the NBS trucks.

    Yours is a C/K style truck.

    Not that it's NOT Heavy Duty (it certainly IS!), just that you may be confusing some people by having that HD at the end.

    Are you using 2 or 4 gauge wire? And does it make a difference if you go to the top terminal versus the sides?

    I'm almost 100% sure it's 2 guage. I KNOW the + red wire is definately 2 gauge.

    Side or top, or any combination doesn't matter.

    I like using the top terminals on a duel post battery, only so I can use the side terminals to power accessories. Like snow plows, salters, DVDs, MP3, satellite radio, 12v/110 inverter, and the prerequisite lit bobble head:rolleyes:
