im putting in a battery isolator and im trying to figure out withch power wire from the battery + terminal is the one from the alternator is it the one right there but the battery terminal or is it the one that's down and off of that red thingy.

 

black wire with red tracer...

you can't miss it

 

yea there are 2 of them.. one to the top of the battery and one off the red thing that kinda drops off to the back of the battery. both of the wires look exactly the same black wire with red stripe.

 

go with the one that goes the fuseable link block on the positive cable

 

you can check continuity with a multi meter..... attached one lead to the alt + terminal, and the other to either of the wires connecting to the + battery terminal, when it beeps, you have your match
