there is no "side". the bolt/nut where a wire is run to ur battery is the positive "outlet", and the case is negative.

trace the wires from the positive terminal on your battery. Whichever bolt on the alty is attached ot the posi on the battery is your positive.

I'd kinda think this might be wrong.

seeing as there is an insulated terminal, and an uninsulated one..

one would assume that the insulated one was positive, while the uninsulated is negative...

but I have a better idea...

use a multimeter!

insulated and uninsulated? u have one wire running form ur alt to ur battery. well, atleast u should. that's ur positive. but i agree, use a dmm. it's pretty simple...

the bolt that gets the constant 12v is the positive one?
