battery relocation problems

[2fast4love]

im just wondering if anyone has run into starting problems with them being relocated. im having major problems with my camaro that has the battery in the trunk. im not sure why but if someone could post a relocation 101 i would appreciate it. i have a 1000 ca battery, 2gauge welding wire for positive cable, and a brand new starter with bypass switch to jump the selonoid thanks

I had mine in the trunk on my 5oh, Had problems starting until I put a big, heavy gauge ground from the engine to the frame.

X2 need to make sure engine is grounded. Is the neg to the frame or a body part? Needs to be to the frame. Did you solder the ends on the welding cable?

no i didnt soder the ends to the cable. i actually just crimped the ends. i grounded to the body its a thirdgen so its a sub frame car. i didnt really know where to shoot for on the negative cable. i do have two negative cables one on the engine to the body and the other the engine to the body. the car didnt have this problem at first i guess it just got worse and worse. thanks alot everyone this is alot more help than what i got in the third gen board

Yep you need it to the frame.

make sure you have a solid connection going through the ground. body/frame/ or even another 2ga wire

I always over-do the whole ground cable to chassis/engine/battery to be safe. Remember that your starter is grounding itself to the engine block (atleast in some vehicles) and so are some accessories and so on. I would hook the cables up like so:

4-6 gauge wire to chassis from battery(short cable to bolt or screw to chassis in trunk)

4-6 gauge cable from battery to engine block or heads/intake

4-6 gauge cable from engine block to chassis

Your car is a big ball of electricity and the chassis is a valid ground from most anywhere. I once bought a car where the previous owner had rebuilt the engine and then put the ground connection on the rubber motor mount and the engine would randomly start.

you can solder a large lug on the positive with a propane torch and solder, that will give you a good connection on the positive.

if you are talking about soldering directly to the battery..... i reccomend against it unless you seriously know what you are doing.....

I did something similar in my monte by moving the bat to the trunk. the bat is to the frame and I have all the motor ground straps in place but I did something different with the factory ground cable that I left attached up front and ran that to the frame also. figured what the hell cant hurt.

SO did it work?
