troy Posted September 29, 2009 Report Share Posted September 29, 2009 technically the best grounds are the bolts that actually ground the alt. like stated above thats the point of the big 3 is to reduce resistance with the grounds.

Boon Posted September 29, 2009 Report Share Posted September 29, 2009 For SPL, if I'm shifting 1000A the length of the car and I can get 0.001 ohms less... that's still 1V (!!!!!!) at the end of the day which is probably worth at least 500w to me. Daily, meh. Upgrade the battery -> chassis ground and ground it properly in the back and you'll be sweet. Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
finkster Posted September 30, 2009 Author Report Share Posted September 30, 2009 lots of good replies here. Thanks fellas. Ill get a chassis reading when i go over to my friends house either tomorrow or Thursday. I think this topic cleared up a lot of talk about grounds in general.

Boon Posted September 30, 2009 Report Share Posted September 30, 2009 Don't bother trying to get a reading unless your multimeter says Fluke or similar on it and cost upwards of $1000. It'll just say 0. Or the resistance of your probes. There are special ohmmeters out there for reading the difference between 0.001 and 0.002 ohms but the better way IMO is to use a good clamp meter and a good volt meter and shift some serious current through it then measure the drop Quote 10.x volts fo' life!
