re-wiring battery to the boot
ive heard that doing this can be slightly dodge for some reason, cant remember what was said, be it earthing or the length of the cable.
anyone thats done this allready, can you get a good enough earth from the body in the wheel well, or is it best to extend the earth from the bay ?
the body is the body, doesnt matter where you attatch it to just make sure it is a good connection. as for the power cable, this can be dodgy if you dont use big enough cable. ive seen a guide before, ill try and find it for you
It can be dodgy if your cable is allowed to move or rub through the insulation. Done properly its not dodgy at all.
decent cable and fitting is the answer.
Just a simple bit of advice.... Dont bodge it.
I'd drill a hole in the wheel well and weld a nut or a bolt to it to ensure getting a good, solid earth point myself. Also unless its a gel type battery like an Optima (specialist ICE battery), it will need to be in a battery box and have a breather tube connected that vents outside of the car, just incase there's a hydrogen build up (remember making hydrogen go pop in a test tube at school? don't want that happening in a car!). Positive cable will need to be fairly heavy duty stuff, consider 4Ga the minimum, 2Ga would be a good idea.
whats wrong with the back bumper bolt as an earth point??? its what i always use
Get a pair of cheap as chips 3meter jump leads of eBay for £10, instant neg & pos battery cableremove the jaws and your onto a winner. As for a hydrogen breather tube, waste of time IMO.
I did mine thus:
Neg/Earth Bloted through floor pan with large washer contacting bare metal around the hole for max surface area contact and then painted to seal against rust.
I put mine here for weight balance (more to the rear and left)
As advised, best go for quality cable:

Ref: 315 will be thick enough. I used this in conjunction with appropriate sized convoluted tubing they also sell just to be safe (and a shiney black hose is a preference over ugly red cable :-)
cheers for the info lads
i think ill combine all your answers with a setup ive got in mind
