minn kota powerdrive

[quilter]

I have a 40 pd thrust ser# mkab1856248. motor won't run, I pulled the motor apart and the brushes and armature looked new. the relay clicks when you turn it on. the prop had a lot of fishing line behind it. I don't have a repair manual for this motor. I suspect the control board motor is bad, the battery is full charged. Any help would be appreciated. anyone know where parts are available? thank you

Re: minn kota powerdrive

There are two types of drives, one with two wires and one with 4 wires, the two wire unit is variable speed while the 4 wire units and three speed units, I am not sure if they have relays in them, I click you probably heard is the switch engaging, if you had the motor apart, you may have compromised the integrity of the water seal. however, if you connect a two wire unit (red/black) wire directly to the battery, your motor will go full speed, then you know your control is screwed, if you have the 4 wire unit, then the black is your common and red is full, yellow is slow, blue is mid. try connecting the wires directly to a battery (black/red), polarity does not matter as it will either go forward or reverse, at least that way you will know if the motor is good.<br />hope this helps..

Re: minn kota powerdrive

On the powerdrive units there are two motors: one to steer and one to turn the prop. Again, which one is not running?<br /><br />On all power drive units the prop motor is continuously variable. It is varied by modulating pulse duration to it with a silicon controlled rectifier. The "width" of the pulses is varied by the sliding "speed control". That is what MK calls the "maximizer". There are two wires to that motor. <br /><br />In some (early) controllers there are no "constant on" and "on" switches to activate the maximizer circuitry. The speed control goes from zero (off) to ten (full speed).<br /><br />In later controllers you can set the speed control and leave it, then use the "momentary on" or "constant on" switches to turn the maximizer on and off.<br /><br />That is why I asked which model you have.<br /><br />The steering motor is bidirectional, single speed and also controlled by silicon rectifiers in response to the switches under the foot pedal. It will have three wires.<br /><br />If you have a recent model it might be less expensive to convert it to Co-Pilot control than to replace the foot controller.

Re: minn kota powerdrive

The same with me. I have a 50lb Minn Kota Powerdrive w/ Mon/Con button. The relay is clicking, and the prop motor does not turn. Any ideas?

Re: minn kota powerdrive

The PD controller is not protected very well from water intrusion. I always stow mine in a hatch overnight if the boat is uncovered.

Re: minn kota powerdrive

Well I bypassed the relay block and the prop turns fine. Does that that mean I need to replace the whole black relay block? And where do you get it?

 

[Rattletrap]

Re: minn kota powerdrive

I ordered the relay block from Minn Kota. I will not be down but just a week. I'll tell ya though. There is not much protection covering that block.

Re: minn kota powerdrive

I had the same problem with my PD40. The foot switch needed a cleaning, and took about five minutes!

Re: minn kota powerdrive

My prop rotates fine now. BUT!!!! Now it will only steers left. How do ya fix the steering issues?

 

[Silvertip]

Re: minn kota powerdrive

Check the "right" steer switch on the foot controller.

 

[Rattletrap]

Re: minn kota powerdrive

The contacts are rusted underneath the plastic coating beyond repair. I heard somebody say it's cheaper to upgrade to the Copilot, than buy a new foot control. Does anybody know about that?

 

[Silvertip]

Re: minn kota powerdrive

You can periodically find the foot controls on e-bay. Seems to me the corded co-pilot is about $100 and the wireless version is $199.

Re: minn kota powerdrive

They have them right here on I-boats. Best price you'll find. Looks like they're out of stock currently, but you can probably get an expected in-stock date with a simple phone call..

Thanks for the info.

Re: minn kota powerdrive

I have gone through about 4 foot pedals on my 65pd. finally in disgust bought a co pilot unit and have never looked back. simply the best thing i have ever purchased for my boat. no more pedal on the deck space, about 90 seconds to install....a wonderful device.

Re: minn kota powerdrive

Hmmmm. Now the Momentary on my PowerDrive footcontrol does not work. It's about 2 years old or less, and it's my second one. The control board is clean as a whistle, and looks fine. I have to use the slider to manual turn it on and off now. Minn Kota PowerDrives are the worst trolling motors ever made.
