    Default Battery relocation Question

    I have everything to install my battery in the bed, but my question is how do I attach the box to the bed of the truck?

    I know how they attach, but what I need to know is what to attach it to?

    Is there anything substantial under there on the right rear that I can attach it too?

    I just ran the threaded rod hold downs through the bed floor and double nutted them with some large washers.

    I believe NHRA rules state that the hold downs be secured to the frame. I will do this eventually, but so far I haven't had any techs complain about it. Only battery related complaint I've had in the tech line was about a vent tube for the battery box.

    Didn't have it vented or vented to incorrect location?

    I didn't have it vented. Figured since it was in the bed it wasn't a big deal. Well, it was a big deal. Its vented out of the lid to under the trucks box.

    Interesting, so even though it's in the bed (which isn't a passenger compartment) it still needs to be vented "out" of the bed? I don't have mine vented totally out of the bed, but that's easily done with a drill bit and a longer piece of hose...

    Some people believe a full length ground wire to the front of the truck, is necessary. I have done 1 Dakota & 2 Dusters, neither had full length grounds

    That full length ground would just be a waste of 10ft of bigass cable! Totally unnecessary, IMO. Like you, I don't have one in my truck and I would say it starts even better than factory now

    No...
    It just needs to be vented out of the battery box itself.

    Ahh okay, that's how mine is right now. Just out of curiosity, do you have your box mounted to the frame or just to the bed (like the rest of us haha)?

    It's just mounted through the bed with (2) 3/8" dia. bolts, big washers, and double nutted.
    I've been through extended NHRA tech many times and never had an issue with it.

    FWIW, the NHRA rule says:
    "Relocated batteries must be fastened to frame or frame structure with a min. of two 3/8" dia. bolts."

    Not sure if the bed is considered a frame structure or not.

    Guy that yell'd at me in tech was probably a tool. I did it just to please them. Venting the batt box I understand, but out of the truck box???

    Mine I grounded (0/2 cable) to the pass frame rail directly under the batt. Then an equal size cable from the same rail to the block.

    There always seems to be room for different interpretations when it comes to some NHRA rules.

    I'll let you guys interpret how you want. But to me, I interpret the rule to be regarding batteries located in car trunks.

    "Batteries may not be relocated into the driver or passenger compartments. Rear firewall of .024" steel or .032" aluminum required when battery is relocated in trunk.
    In lieu of rear firewall, battery may located in a sealed .024", .032" aluminum, or NHRA-accepted poly box.
    If sealed box is used in lieu of rear firewall, box may not be used to secure battery and must be vented outside of body."

    It mentions nothing about truck beds. I can understand venting a "sealed" battery box outside the trunk body. Makes no sense to vent outside of an open truck bed though.

    I am in total agreement with you.

    This was the argument I tried to make. But it wasn't a big deal to vet it out of the bed anyway. So I did just so I would HAVE anymore complains (right or wrong)

    i would run that ground off the batt directly to the frame rail. then another of equal size from the same frame rail to the block. a good "clean" ground might be all you need.

    hmm, all i'd have to do is move the ground from the carrier. already have a ground from there to the block. i bet those big rivets holding the carrier between the frame rails don't "transfer" the ground well. ill have to check that out after vacation.

    Pete...Run a ground from the battery to the block. Better yet, bolt a grounding lug to the frame in the middle of the truck, ground the battery to that, and run grounds from the block, including everything you have added to the grounding lug...Don't ground anything to the frame only.

    Grounding lug can just be a bolt...Some guys weld the lug to the frame.

    I think Pete's problem may be in the connections between the new cable and terminals/lugs that were put on, not s grounding issue. But, he's gonna need some free time to redo all the new terminals...

    If he's just grounded to the frame, that's gonna be a problem too.
