I recently started having intermittent issues with my trolling motor.  When I step on the foot pedal sometimes the motor comes on, other times it doesn't.  When the pedal isn't working the continuous switch on the side does not work either. 

 

When releasing the motor does work when depressing the pedal, when I lift off the button sometimes to motor shuts off and other times it doesn't. 

 

I recently rewired the boat and replaced batteries and breakers.  I have voltage at the plug when the motor doesn't work.  

 

I'm looking for suggestions on what to look at.  The first 2 thoughts looking at the Minn Kota diagram are the momentary switch or the control board in the pedal.  It's not clear to me from the schematic what else could be the issue.

 

Any help would be appreciated.

It's probably the foot switch.  I've had it go out on a Maxxum.  It's not hard to replace.

Yep, I would start worth he foot Controller.  

The next time it does not start, turn prop by hand about 1/4 turn, and try it again, if it starts working, replace the armature. It will have a bad spot where the brushes ride. This can happen from from prop being stuck in weeds and not turning while button is depressed. Had it happen twice before I figured out what not to do 

I don't see a foot pedal switch on the variable speed motors.  I see it on the 5 speed motors, but the variable speed look to be wired through the momentary switch.  I ordered a new momentary switch and will replace that and see if it solves my problems.    

 

I tried to manually turn the prop with no luck.

 

I have Minn Kota C2 30

and it was cutting off after a while. Reverse was the same way. Got home checked electrical and everything was fine. By chance took prop off and it was full of fishing line. Got it out ran it for 30 minutes forward and reverse. Will put boat in water Saturday.
