Well im cuttin the passenger side wheel well out... to the point where i have to relocate hte battery im relocating it to the bed i have an identical battery as the one thats in the truck now so im goin to run dual batteries im going to use a continuos duty selanoid to isolate the main battery and the aux. battery question is what gauge wire to run to trigger the selanoid im going ot have it switched so that only when i flip the switch will it charge the aux. battery..... i have a pretty good idea on how to wire it up but if anyone has a diagram post it i will be very greatful..... no real need for a dual battery yet..... but liek tim taylor always said "MORE POWER" that and since i got fucked outta my old fuel cell and had to get a new one were puttin a electric fuel pump in ill have a lil more power
Run a dual battery isolator, RV stores sell them for less tahn 100 bucks, and the trigger wire only has to be like 16 gauge...the actual feed power wires should be 4 gauge or bigger.....and so should the grounds.
