I wanted to run my livewell pump off the trollin bat. to keep from draining the start bat.
I took the hot wire off the switch and ran a new one to the TM bat. Then I connected the NEG from start bat to NEG of TM batt. To take care of the ground.

[beagle man]

that will not work. you will have to run the neg. wire first

It does work. Works fine

Did you fuse the wire? Locked rotor draws a lot of current. Fire hazard.

Yes 5amp 16 ga. wire. What about the Grounds connected. Should only draw from TM bat. right?

[Cane Pole]

I use a car starter cable to tie my battery grounds together. Big is good.

Be careful not to do this if you have a TM with a built-in transducer. Some of them don't like the batteries sharing a ground.

I was told that is the way to get rid of interference. I think there is schematic of it somewhere on here that CP drew up
