DIY: Battery Relo

FricFrac · 06-03-2009, 10:17 PM

I've measured the stall current on a 540 can 27 turn motor at 90A... thats just a tiny little motor you'd find in a power drill or R/C car. I suspect under stall conditions a starter could draw more than double that but that's just a guess. Depending on the resistance in the fuse you will probably be droping some voltage on the fuse -not a lot but some. My other concern would be ground loops. I'd definately run a heavy ground up to the front of the car with the positive cable. I would also make sure all the car's computers are grounded to the battery directly to eliminate any issues....
