I have a Minn Kota model 40PD which on my last outting ( operated by a rookie friend ) grounded and melted the 30 amp fuse holder - I hope the motor is OK. I was told to replace with a inline breaker type fuse? I`am at a loss why the fuse didn`t blow before melting the holder - any answers or suggestions.

Re: Trolling Motor

The fuse holder melted because the motor draws more current than the wiring was able to handle. It may also have become hot due to corrosion at the terminals. A 40# Power Drive can draw a maximum of 42 amps. Not only is the 30 amp fuse too small but the wiring for the motor is likely too small as well. There is no such thing as a circuit breaker type fuse. YOu either have a circuit breaker or a fuse. Circuit breakers are available in automatic or manual reset. Fuses are a one-shot deal. If it pops you replace it. It doesn't matter if you use a circuit breaker or fuse. But either one must be capable of handling the maximum current flow in the circuit. You need a 50 amp breaker and #8 gauge wire.
