[quote dubob][font "Comic Sans MS"][#800000]There is a tag with the serial number on it (MKAE3187239) and on the housing on the top end of the shaft (opposite end from the motor) it says 40PD. It is a Power Drive model of 40 pound thrust. I believe it was made in 2004.[/#800000][/font]

[font "Comic Sans MS"][#800000]While looking at the unit just now, I discovered that this housing at the top of the shaft was partially melted on one side. When I pulled it apart, I could see that the black wire connector inside that housing was fried and open. This is why the motor doesn't turn; no 12vdc getting to the motor with the negative line open. I think maybe with 40 years experience as a radar technician/radar system engineer, I can probably fix that. But it sure would be nice to see a manual that shows how to dismantle the motor from the shaft and the shaft from the frame so that I can splice to a good portion of the remaining black wire inside the shaft and the coiled portion outside the shaft.[/#800000][/font]

[font "Comic Sans MS"][#800000]No indication as to what may have caused the overheating and melt-down at this point. I'll have to put in a splice and apply 12 volts to see if there is something else wrong.[/#800000][/font][/quote]

That PDF has A LOT of MK info in it. I suggest using the CTRL+F function to find what you are looking for. I would just replace that wire, if it got hot you dont know where else the insulation melted inside the shaft.
Then hit it with an Ohm meter once its replaced.
Let me know if you need any help, I deal with DC power and motors a lot in my hobbies.
