Alternator Upgrade

WOW! This is a great wealth of info!Thank you all! My old battery cable did not have a 10 AWG pigtail grounded to the body.My new one has a little piece comming off of it for this.Should I connect some wire to is and ground it somewhere?If so where?

I don't want to overstate the obvious, but just to be sure there isn't a disaster, this is the negative cable we're talking about. :toothy10: Hope it fixes your problem.
