Cadmium plated isolator with terminal nuts and lock-washers. 3 terminal isolator for metal frame ground systems, 4 terminals has inuslated ground terminal for use with fiberglass or other non-conductive materials. Isolates starting battery, provides secondary battery current for auxiliary power and full time charging of both batteries.
I want to use this to disconnect my battery to avoid trickle drain. I want to use to break the ground side of battery. I have spare toggles on dash. How does the switch leg wire work with this switch? do I just need a hot wire to activate I assume? What is the advantage of buying a switch set up with 4 terminals like Joe's Racing Products JRP46215?
Answer this question
The 4 terminal type are not self grounding you would have to ground one of the small lugs. Yes just a power lead from the battery to the small terminal on the battery switch.
