Its very easy:

Reprogramming the Wireless Foot Pedal or RemoteNOTE: This activation procedure applies to the foot pedal and remote.

IMPORTANT: To activate multiple foot pedals or remotes, the motor must be unplugged from the power source and then plugged

back into the power source between activating each control device.

1. Unplug the battery cables from the power source. Wait 30 seconds and then plug the motor into the power source.

2. In less than ten seconds, press and hold the "+" and "-" buttons on either the handheld remote or the foot pedal controller

simultaneously.

unscrew the pedals

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.

You should only use the MOM (or momentary) setting when using the push button the foot pedal. Con will just keep the motor running and your foot control will only allow for direction and speed!

put the old one back on and see it the engine runs if so it is in the connection to or from the cable

The pedal has generally four functions:
1) Forward and back on the pedal make the motor go left and right (push forward to turn the motor right, push back to turn it left)
2) Momentary power - the little 'button' towards the top will engage the motor as long as you press down on it.
3) Selector Swith - on the side of the foot pedeal there is a switch with the following settings Con - Off - Mom (Continuous - keeps the motor going all the time, Off - well it's off and Mom - will only go when you press the momentary button).
4) Speed select - the knob on the left controlls how fast the motor goes.

It takes some getting used to but offers tremendous control and hands free operation!
