I started the dual bat mod and in switchin some wires I figuerd that I just needs to wire a spare jump batt. Well I started the car and Im lossin juice, my alt show .38 - .40 output and I had autozone test it, it checks out .40 then fine for 10 starts. Well I put it back in and same prob. I switch alts and same prob. Whats going on?
