I purchased a battery isolator from Summit Racing last winter. I mounted it to my 99 Tahoe, but never got a chance to hook it up. I finally hooked it up and it doesn't work.
I researched it and it's a standard battery isolator. Apparently, I need a CS battery isolator designed for a GM. The CS type battery isolator has an extra input for the ignition. ???
When I apply 12-14VDC to the center, I get 12-14VDC -0.7VDC at each terminal. When I hook the isolator up to the alternator, it sees ZERO voltage at the center terminal.
Can someone explain why the 4th terminal for the ignition is on the CS battery isolator. Can someone help me hook this standard battery isolator up so it'll work or am I screwed and have to sell it and buy a CS type battery isolator?
Thanks
