| I apologize about all of the questions, but I just bought a new rig and am working out the kinks.
I have to get my Autopilot fixed, so in the meantime, I mounted my maxxum to the bow and and full power it cuts out and looses power for a few minutes.. Then if I wait, it will go again it has to be a wiring issue. Any idea where to start? |

Location: Rhinelander, Wisconsin | Sounds like a heat related auto breaker. Check to see if you have something in the hot wires that looks like a sealed breaker. |

| What size is the Powerdrive vs the Maxxum? Maybe like Steve said, it's an auto reset breaker, and it's too small? |

| If it was just wiring, it wouldn't cut out and come back. Sounds like too small a breaker for the TM at full power. The breaker is there to protect the wiring, not the TM.
Up the breaker, but make sure you got 6 ga if you go to 50A or 60A.

| Wire is downsized from the motor head thru the shaft to the (cold wound motor)......no breaker needed.... throw it away.... |

| I found the issue, it was a hidden fuse, it is a "30" just like in a car and was fried. The next question is, should a guy put in a new fuse, or just wire it direct? Thought? |

Location: Cedarburg, Wisconsin | I've found that when I troubleshoot electronics, run into a current problem that blows fuses, and haven't a clue where the problem is, the way to go is eliminate the fuse. Then when you turn the device back on the problem is easily found when the bad component bursts into flames or explodes. As long as you are wearing safety glasses and have a fire extinguisher handy I'd suggest just jumpering across the fuse with some heavy wire.

Location: Elk River, Minnesota | Hiya,
I'd start by replacing the fuse and see if your problem still exists and blows another fuse.
I would agree with Steve Worrall, though in that if there is an automatic breaker installed, (normally right at the battery terminals) I would be checking those.
Where was the hidden fuse at?

Location: Eastern Ontario | A blown fuse shouldn't start working again only a self resetting breaker would do this |

| Maybe this is a self resetting breaker, It was feet from the battery on the positive wire, it was fried and melted, needless to say it was not resetting last night. But it did have that 30 fuse in it?? |

Location: Cedarburg, Wisconsin | Minn Kota lists the Maxxum as having maximizer circuitry on selected models. That circuitry is a pwm firing arrangement to let you run at variable speeds without bleeding off power through a resistor, something old school motors did long time ago. This circuitry, if it is in your motor can possibly have components failing with heat, meaning they will function until the heat gets high enough and then they do something they were not designed to do, turning off the firing that runs the motor, until they cool enough to resume operating as they should. If this is the case the components won't last much longer.
So it doesn't nescessarily have to be a wiring/fusing issue although that is still the best bet and the first thing I would eliminate.
Always start with the power supply. Make sure you have the full rated voltage at the wires leading to the motor. 12.68VDC for a 12 volt application on a fully charged battery, double that for a 24V application. If you have power, run the motor and then measure again when it stops to see if the power is still at the plug or if it's now missing. If it's missing, it has to be an inline breaker/fuse that is tripping or a battery that is in really bad shape. If it's in the motor it's harder to figure out unless you have a visual clue to a failed wiring section or component. Good luck fixing. |

What? No breaker needed? That's a ridiculous statement.
If you want to risk starting a fire, then go ahead and don't protect the wires with a fuse or breaker.

Absolutely not.
Please answer the following.
1. Is there just the one fuse inline?
2. 30A?
3. What is the Maxxum rated?
4. No other Circuit Breakers off the batteries?
5. What size wire do you have from the Batteries to the TM?
6. Pictures of the melted wire and any fuses or breakers?
