Thread: For all elec guroos

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.

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.

I was gonna use 6ga.

That should be fine. If you have sonar interference, well you will have to home run the ground from the pump and remove the jumper. Grounding sucks.

The Minn Kota us2 has a sneak path to ground if the shield (knurled connector) is grounded. This connector shield is isolated with the Humminbird, but still creates some problems. Again, a lot of the noise is inconsistency in the manufacturers equipment, such as the boat wiring layout itself.
