1. Short in the trolling motor itself
2. TOO SMALL a ground wire. ..need at least 8 gauge wire!!!!
3. Bad/dirty/corroded battery connections
..Make sure your battery/trolling motor is not accidentally touching the metal boat.. DO NOT CONNECT ANY WIRES TO THE BOAT!!! - PERIOD!!.

I would check the battery. If you're using an old or under charged battery you will loose power for sure. Make sure you're also using a 12v deep cycle marine battery as this will ensure proper operation and a longer battery life.

Wiring diagram for a minn kota mk220 2 bank charger


First. the +/positive/hot wires go to the respective/separate +positive/hot side battery terminals.. and the -/negative/ground wire go to their respective/separate -/negative/ground battery terminals.
The wires from the charger are "paired out".. meaning the + and - pair must go to the same battery. .. you can't mix and match.

How does the minn kota 65 all terrain run on 24


You should only run the motor with a 24v battery or two 12v batters 'jumped' out. To jump the two batteries, connect the positive on one batter to the negative on the other battery and hook the trolling motor battery cables up to positive and negative terminals that are NOT jumped out as you would normally. Don't run this with 12v as you will have serious problems if you do. They do not make a 65lb thrust in 12v - too much pound thrust to run off of 12v.
