I have two batteries on a switch, the second one will be for the trolling motor and backup starting.
I know I can run a wire from the positive to the ignition input, and the negative to the ground input on the gauge, but this will drain the battery, (slowly), since it would always be on. Any way around this easily? i was thinking of a relay actually but not 100% sure on how to wire it and partnumbers
