Hello,
I am in the same boat as you. I have dual batteries, and my Aux batt powers a fuse box that does NOT have a Stinger to turn it on, it's always hot. I want volt meters for both my batteries, and would power them from the Isolator. This would cause them to be always on, so I want to switch the grounds. If both the grounds connect to a switch to kill the cycle, i could turn them both on with one switch correct? Power from the batteries, disconnect he grounds.
Then, if this is how I do it, I will not be sure how to wire a rocker switch that lights up when they are on. To keep the switch from being lit up constantly as well.
Thanks for any assistance.
