Battery cut off switch

I use a marine type (Perko) switch that allows me to use an extra battery. With it, I can use each battery separately, both, or shut off both. I carry my second battery in a boat type battery box strapped down in the truck bed. If you ever plan on having an extra battery, I'd install that type of switch now. Or, I'd tell me to mind my own business and use whatever I wanted to!

Question-- If you put the switch on the positive pole when you put the switch in the disconnect position does it not spark??? Also when put the switch in the connect position will it not spark??? T-10

Mine is connected on the positive side. Either way will work.

Some will say put the switch on the battery negative side and others will say the positive.

Really doesn't matter for the switch as all you're doing is breaking the circuit.

I would do the Neg. side. Put switch between the battery and ground. Just my thoughts on it.

Just one

dealer told me it goes on the negative side. hope this helps

One side is good enough. I would suggest the small post top knob type as it should fit within the battery box.
