Boat wiring question
So I bought this console for my boat. I’d like to run my trolling motor through the voltage meter and I’ve got a separate battery for fish finder and USB. (When that runs out, my electronics just turn off. If the troller dies, I’m paddling.)
It makes sense to me to just disconnect the voltage meter and reconnect those wires to bypass it, but when I wire the trolling motor through the voltage meter do I just run the positive or do I need to also connect the negative? It’s also a larger gauge wire. Will that matter?
Thanks in advance!
