Battery Ground

[scogin918]

I have the Detroit Speed battery relocation bracket. They gave me a long length of ground wire but I would like to find somewhere close by to run it. I have solid body mounts so it should ground the car well enough. Any suggestions?

[speedster]

I run my ground wire (600V very fine welding cable) to the front and have a big junction block that everything ties to. Even though you have solid body mounts, you probably had the bottom of the car painted or undercoated (I doubt you had bare metal). The last thing you want in you ride is a ground loop.

I hooked my ground cable right to the frame.

Hmmm, that makes me wonder, I relocated the battery to the trunk, then I used the 1 Gauge cable with a hole and grommet right through the trunk floor to the rear frame rail. I ground off the POR-15 and drilled and tapped a hole and I ran a bolt through a ring terminal end on the ground cable into the hole. I am using solid (aluminum) body mounts, the entire underside of the car is coated with POR-15 and I have grounded the front of the Camaro to the frame and body and engine, so that they all interconnect. But I am having a few electrical gremlins, mainly with gauges and the RS headlights, could this be the problem?

[CAMAROBOY69]

Yes that could be the problem. Since the ground is only hooked to the rear frame rail, there isnt any way for it to really get to the front frame rail since your car is all coated in por-15. If you had sub frame connectors then it wouldnt be a problem at all. You could try to bring a strap from your rear frame bolt hole up into the body to test that out. That should complete your ground from front to rear of the car since you said you have the front frame grounded. Keep in mind the bolts that hold the body on go right into the floor. So you could also run a strap that way but it wouldnt be the best route.

The ground in the trunk only can be connected the wheel well in the trunk. You can connect it to the fram rail, but the wheel wells are connected to the floorpans and there is no advantages plus it eliminates the need to drill though the trunk. In addition to the rear gound run one ground from the subframe to the firewall, and then two grounds from your engine to the subframe. Also use the same gauge wire for the + battery and -Gnd connections.

When I relocated my battery to the trunk I was told by a few very experienced mechanics that the best ground is to ground it to the back of the transmission. So, I drilled a hole throught the floor and ran it to a bolt on the transmission. I have never had a problem. In fact I am very happy with the performance of my electrical system.

I have had new tubes made for my car so can I still ground the battery to the tubes? Can you run the ground cable back up to the front of the car & connect it in the same place the factory placed it?

[Damn True]

If I'm not mistaken DSE recomends running that ground back up front to the block. I don't have the text in front of me, but it had something to do with the resistance of the frame vs the cable.

[MikeDVC]

I had trouble grounding to the rear of the car, so I ran a cable to the front. The ground in attached to the rear of the pass. side head using a stud, so I can easliy remove and install the cable.

I am going to use the New System from www.madelectrical.com along with his trunk mounted kit.

[streetrod77]

Thanks, I was wondering about that. I thought it would be better to run it back to the block. I just hate to run 2 #1 gauge wire to the front, I think it may be seen under the carpet.

[Damn True]

Dude, you can't see a subframe connector under the carpet. How are you going to see a wire?

Do what I did, tuck the cable in the channel which runs from the rear wheelwell, under the sill plate to the front kick panel you will be fine.

No matter where your battery is you need to make sure that every part of your car where ground is needed has a proper ground connection.

You need to make sure that the starter alternator and block are all properly grounded, you need to make sure that your body and your frame is properly grounded as well.

Every car that we do, we run a ground from the chassis of the starter, the chassis of the alternator all to one spot on the block, we then make sure that the block is well grounded to the frame, we then make sure that the frame is well grounded to the battery and the main car body is well grounded to the battery.

Every piece of electronics or electrical connection has to be grounded where it is at in the car............you have to ask yourself if everything is properly grounded or are they trying to find ground thru whatever they can.

Case in point, most stereo shops will not bother grounding out their radios because it works when you plug in the antenna (antenna is grounded to the car).............is this right ? Hell no...............most will use the ground that is in the factory harness, is this right ? Depends on the current draw of that deck.............safe bet is to always ground it to metal.............

Will you come to CA when the time comes to wire my car?

Possibly

It would be about the same though to have the car shipped up to us.

We have some really good rates when it comes to vehicle transportation.

[streetrod77]

Thanks for the help. I picked up the battery this weekend but I also found out I need an alternator too. I will bee looking for that this week.

[vanzuuk1]

I have my antenna and speaker wires in the sill, will the battery cable cause interference?

[CraigMBA]

I can vouch for Tim. He's a acomplished installer. I'd let him work on my car any day.

And believe it or not, we have personal issues between us.

Todd says hey BTW.
