Tantrum battery hook up
 

Hey guys... Call me stupid but when U took the batteries out of my boat last winter I forgot to mark the wires. Can somebody tell me how there's is connect. Specifically the jump wire that foes from one negative to the other. Also I have a thin red wire coming out of the switch with a fuse on it. Which positive does that go to?

I dont think it matters with the skinny red.
jump your Neg.'s together.

You have two batteries?

dont most boats.

Is this another inside joke Im out of.

I have one battery. No need for another. I do carry a booster pac for emergency.
