I've been looking at battery cable kits and bulk cable/terminals that are available. The cable kits are high, but all the little stuff ads up too. What is the best way to go here? Also, should I use a full length ground cable, or should I use a short cable to frame, then another to engine block? Another question I have is what gauge cable is best to use? The positive cable will be approximately 8 feet in length. Any suggestions?
