Fish4Eyes Posted August 31, 2009 Report Share Posted August 31, 2009 (edited) This unit has to be 10+ years old. The problem I'm having is that it will continously work, and then the motor stops. The steering on it works still when the motor dies. After I turn the steering back and forth, adjust the speed up and down, and press the continous thrust buttom on and off, it comes back to life and starts working again. And then it dies again at any given time. I can hear that it makes a noise within the motor when it does not want to produce thrust. The noise is not continuous it just makes a little tick noise for a split second as soon as I press the pedal for it to thrust. It seems like its a bad connection to me. Another thing I noticed is that when I activate continous thrust it does not always want to work. Any suggestions, or anybody have similar problems?

danbo Posted August 31, 2009 Report Share Posted August 31, 2009 The prop shaft is bent. Bend it back to free it. Link to comment Share on other sites More sharing options...
SRT8 smoker craft Posted August 31, 2009 Report Share Posted August 31, 2009 have you ever had the prop off ? I would pull the whole bottom end off and clean the contacts and brushes with electrical contact cleaner and make sure theres no line wrapped around the prop shaft if that doesnt work find a dealer that repairs them it could be the pedal itself the older ones used to break down alot might need to replaced they are pretty easy to work on just make sure you put it back exactly the way it comes apart I found that out the hard way Link to comment Share on other sites More sharing options...
Fish4Eyes Posted August 31, 2009 Author Report Share Posted August 31, 2009 Never had it off no. Thanks for the advice guys! Link to comment Share on other sites More sharing options...
Fish4Eyes Posted September 1, 2009 Author Report Share Posted September 1, 2009 So I pulled off the prop, and the prop shaft was not visibly bent. There was no water inside the motor either. I checked the voltages on the pedal and they were ok too, aside from one of them being more than what the Minn Kota diagram specified. One thing I did notice is that the 12V source connectors were not really connected properly as the connectors just pulled apart with not much force at all. After cutting the wires to reconnect it back together I noticed the copper wires on the positive were black. I cut off another 2 inches and they were still black. The negative copper wires were not. Is this the result of overheating? If not, what causes this? Any suggestions? Do you guys recommend connecting the wires back together by soldering or is shrink wrapping or connectors ok?

msp Posted September 1, 2009 Report Share Posted September 1, 2009 Check Aikmans sporting goods in Mississauga. They do Minn Kota work. Or you can buy a new one there for arouund $150 Link to comment Share on other sites More sharing options...

Garry2Rs Posted September 1, 2009 Report Share Posted September 1, 2009 check for stuck brushes. I have had the same problem. You might need two Hacksaw blades to reinstall the armature. Link to comment Share on other sites More sharing options...
BITEME Posted September 1, 2009 Report Share Posted September 1, 2009 The black is a result of oxidation shine the wire up or keep cutting it back till its clear get some quality marine ring connector and some of the same in splices good marine connectors have epoxy in the shrink tube and will make a water tight seal when connected From what you have described it is lousy connections side note at your battery put vaseline on the posts and connections after you have them screwed down Link to comment Share on other sites More sharing options...

Thanks for tips! Edited September 1, 2009 by Fish4Eyes Link to comment Share on other sites More sharing options...
BITEME Posted September 1, 2009 Report Share Posted September 1, 2009 west marine sometimes canadian tire in the auto section vaseline makes a barrier against corrosion Link to comment Share on other sites More sharing options...
Whitespinnerbait Posted September 1, 2009 Report Share Posted September 1, 2009 I'll be posting some pics of the wiring problem in found with mine ....the spaded terminals heated up and melted the wiring....... Link to comment Share on other sites More sharing options...
wallyboss Posted September 1, 2009 Report Share Posted September 1, 2009 (edited) I had the same issue with mine ,. when you take the pedal apart you will see where the foot switch put's pressure on a plastic tab I just added a bit of electrical tape to make the bump a bit higher(on printed circuit) and now the tab makes full contact.

DRIFTER_016 Posted September 1, 2009 Report Share Posted September 1, 2009 I had similar issues with my 18 year old Auto Pilot. Turns out the pedal was shot. Replaced it and all is good. If you still have issues after cleaning up your wiring pick up a new pedal. About $70 and available at LeBarons, Bass Pro, Cabelas etc. Link to comment Share on other sites More sharing options...
Fish4Eyes Posted September 2, 2009 Author Report Share Posted September 2, 2009 Seems like it is the pedal. One of the resistances is reading infinity, which means there is an open circuit somewhere. Me and my brother disected this trolling motor in every possible way last night. We hooked up a 12V power source directly to the red/black wires at the top of the motor shaft and the motor spun instantly, which rules out the bottom end being an issue. We also checked the circuit board directly behind the steering system and all wires received a voltage. Wallyboss: I also noticed wear on the tab, and I did put some electric tape on it to help it make contact better, but still no dice. DRIFTER016: That will be the next course of action, if it still don't work I can just return it. Im just confused because when the pedal is pressed you do hear a relay click in the circuit board behind the steering system (which tells me it is getting the signal ). Is this normal even if the pedal does not work properly? DRIFTER016: did yours do this when the pedal was faulty? Link to comment Share on other sites More sharing options...

I ordered a new one up from LeBarons, plugged it in and all is good. Before the new pedal was installed the direction worked but no prop spinning. I went through all the same testing as you before giving in and buying the pedal. Pretty much a waste of my time as there have been lots of posts on various boards about pedal problems with this model of pedal. It's an easy fix though.

Fish4Eyes Posted September 3, 2009 Author Report Share Posted September 3, 2009 Plugged in a new pedal and all is good. Thanks to bitsmith2k for hookin' up the pedal, and everyone who gave suggestions. Link to comment Share on other sites More sharing options...
