How do i test the control board on minn kota maxxum 80lb?

I took the motor of my trolling motor apart. I had an issue getting the brushes back on but figured that out. A couple of the wires came undone and i plugged them back before closing the motor up. Now the trolling motor doesnt work. It makes a subtle buzzing sound in the pedal and the head. one of the wires in the head got hot near a connection. I repaired it. It still buzzes. i can feel the wire buzz. i believe it was the red/black one. What could be the issue? I am going to take the motor back apart and check that i plugged them in the right spots but im almost certain i did. i have tested the outlet and the connections at the board. I get 12 and 24 volts in certain combinations but im not sure exactly what will determine if its working.

My guess is you either have a brushwire against the housing or the leads are on the wrong terminal. the red/black goes on the same as the lower brushwire and the black goes on the same as the upper brushwire. The motor should have a 60A breaker, assuming you have 6ga wire. If wire is smaller than 6ga, the breaker should be downsized. To test the control board, check the voltage in and voltage out. Voltage out should vary as you turn the dial.

The trolling motor will just quit sometimes if I shake the handle several times it will start back up

sounds like a loose or bad connection on the throttle switch will need to open the control tiller and check connections if you have a meter ohm out the wires at the connector and switch to make sure all connections are good this is a bit involved and I recommend doing on a bench not in the boat If you need more detail just ask You know this sucker comes with a 2 year warranty right !

Trolling motor stays on same speed no matter where I set the speed 10 -100. It is at a mid range speed.

I just recently had a simialr problem. No speed control and motor only ran at 100. I talked to the minn kota tech rep and sent him my control board and he said it had a bad potentiometer...however, I had to buy a control board to fix the problem ($215). Hate to say it but sounds like you may need a new control board.

Burning out fuses on trolling motor at battery

not enough info. I went the the min kota website, they show four maxxum 80's at different voltages.is it a 12v 24v or larger? without a year model I'll have no reference to what wiring schematic Is the fuse connected inline with the trolling motor? what size amp fuse are you burning up? well I can give you some troubleshooting tips. tools to buy (1) amp gauge. if you are unfamilier with amp gauges make sure you get instruction book with gauge or you could burn yourself. Toubleshooting(1) Remove cover off minn kota trolling motor. black cover ontop of unit were the foot control wires go into.turn over foot control remove cover (2) check for corrosion. any exposed terminals should be cleaned.(3) go to your batteries and clean all connections. make sure the batteries are fully charged.(4) take amp gauge and test positive wire for amp draw as you tun on trollling motor and run it through all speeds. if batteries are in the rear away from trolling motor get a 2nd person to control trolling motor. if the trolling motor is more than a 12v system you will have more than one positive lead to test.GOAL. What your trying to find out is how many amps the trolling motor is really pulling. and at what speeds. under a load in the water and out of the water.how many more amps than the fuse raiting? newer trolling motors come with inline breakers not fuses so I'm guessing your using 30 amp fuses. again without more info i can only guess.

TOOK THE BOLTS OUT OF MINN KOTA AND CANT GET THEM IN. 2 SHORT.

Hi!
Here's a schematic:
Max 74 Bowmount
Make sure the end housing #7has a small mark in it pointed to the bottom (towards the skeg). The bolts can be a pain to line up!
Also make sure the armature is all the way forward it can go....past the brushes is the toughest part to get through and lined up. Keep it up, you'll get it!
Best of luck
Mike

Where can i get a circuit board for my minn kota foot pedal Part # is 9901-200c

http://www.northlandmarine.com/MinnKotaQuickRef.htm

You need your serial number of the trolling motor, length of shaft, and thrust poundage.

or you could call Minn Kota direct and give them the same information at 800-227-6433.

Minn Kota tolling motor

Reverse the polarity on the trolling motor by taking the trolling motor apart and turning ithe motor housingt 180 degrees and bolt it back up. The polarity will be straight then. I did the same thing when I pulled the armature back in.
