Trolling Motor Foot Pedal Help

[blue79]

I have a Motorguide Brute 756 24volt 56lb thrust and i have lost power.

The 12v/Off/24v toggle switch was broke when i bought it off of craigslist 3 years ago so i just wired it for 24volts(no 12v option)

I have 24volts to the plug

I have 24volts to the pedal switch(micro switch) but nothing happens when i step on the pedal.

If i put 12volts to the plug i have 12volts to the pedal switch(micro switch) and it works and all 5 speeds work on the rotary switch.

I cant understand why the switch will let 12volts go through and not 24volts when it has been 24v for a couple of years now.

I would think it would let all the power go through or no power at all.

I would think it would throw my breaker if it didnt want 24 volts.

Is there any way the motor is starting to fail and not allowing 24volts,or is it in the switches?

I dont want to waste money on the micro switch,toggle switch,or the rotary switch if the motor is starting to die.

Do you think it is the pedal switch(micro switch) or something else?

Does someone have a pedal to sell?

Thanks blue79

Wild butt guesses here, but that's how I work on my own stuff. Underneath the switch on the foot pedal that you step on, there is a rubber cap that is supposed to keep water out of the switch. Make sure it's not worn. If it is, it won't depress the actual switch which lies underneath it. The other thing is that the switch you bypassed would melt internally if I used it on 5 (high) for too long. Make sure you have continuity through the switch and that the terminals haven't melted away inside.

You've eliminated the red (12v) wire completely from the system, correct?

If I understand you right then you should be only connected to the white (or orange) 24v circuit, and the black (Gnd.)

Just start following the voltage AND the ground, beginning on the upstream side of the switch. If there's no voltage loss on the downstream end of the switch then follow it to the rheostat (speed switch), then to the spade terminals under the top motor cover.

Be sure to trace the Ground also as you go...rather than only moving the red meter lead.

i replaced a couple small wires that looked really tarnished(not burnt).I havent checked the voltage further than the pedal.Im gonna go fish the dock in the morning and gonna take more tools and look into it more.
