Tried to switch out the batteries and didn't work. I must have to get it fixed. I don't not have a white puck . I tried it again today and did the same thing. Thanks for the tips 

Hello I was wondering if anyone could help me with my minn kota ipolt lock spot. Every time I hit lock spot on the trolling motor the motor goes back and fourth and then spins till the cord is completely wrapped around all the way till I shut it off. If it doesn't do this it clicks into 9th gear and takes off till I shut it off. Anyone happen to know how to fix this ?
