I just entered your motor on Search (motorguide magnum) and there were several sites that are suppose to carry parts for it. If you contact them by computer or find their phone number, they can help you.

It should but may not run at it's intended potential. It may also run your battery down a lot quicker.

This is most often caused by a faulty 24 Volt, section, (usually damaged output semiconductors, or the drive?) in the speed controller, fault, the only "Fix" is replacement. Simply obtain the entire speed controller and replace it "En Bloc" as it were. You will need to also obtain a service manual so you can disassemble it and obtain the parts numbers for the replacement parts.Otherwise take it to a professional and ask for a "Quote" as to prospective costings and go from there.

SOURCE: Wire going to prop of Motorguide trolling motor shorted

Unless you are mechanically inclined, dont attempt this. Take the lower unit apart by removing the prop and removing the two bolts that hold the forward and aft housing to the center housing. Fwd being the cone shaped part. Pull the aft housing away from the motor so you can inspect the connections to the board that holds the brushes and the soldered wiring terminals. You should find the solder missing from at least one of the terminals that connects the wiring from the foot switch to the speed control windings inside the aft housing. Clean up the terminal and wiring and re-solder. Also re-flow the solder on the other terminals. Clean up the seals and the area where the seals meet the housing parts. Replace seals if damaged. Reassemble the lower unit and torque the bolts 45-50 in-lbs and no more otherwise you will fail the seals. This problem is due to a "cold" solder joint that creates a high resistance to elec current flow and heats enough to melt the solder. This is a result of poor quality control at the manufacturer. Good luck.
