Motor Guide Wireless Remote Pairing.
To pair a new remote, disconnect The trolling motor from batteries and re-connect. Then, within 10 seconds hold the + and - buttons until you hear a long beep indicating the remote has been paired.

I have one the New 115 Thrust and had the same problem.
This will correct your issue.

I found a website called Partselect.com and they have very good pictures of exactly the part I need. I ordered it from there.

Here is a picture of the wire connection for 24 volt. Compare to yours is it correct? If it is, I wish you listed make and model I could of sent you the right picture diagram of you motor. Use this picture as a starting point. Test the wires through the motor testing for 24 volts. Again if I knew make and model I could show you exactly were. Last if voltage is correct all the way through. The motor is the last thing to tear down. If the brushes or armeture is damaged in anyway, or manufactured wrong, it would lead to power loss.

According to: http://www.northlandmarine.com/MinnKotaMotorControlBoardAssm.htm

*Note: Newer model trolling motors have serial numbers beginning with the two-letter prefix MK (Minn Kota), followed by a two-letter year code. MKAB .......... 2001
MKAC .......... 2002
MKAD .......... 2003
MKAE .......... 2004
MKAF .......... 2005 MKAG .......... 2006
MKAH .......... 2007
MKAI ............ 2008
MKAJ ........... 2009
MKBA .......... 2010 A serial number with the designation MKAB denotes a
2001-motor and MKBA would be a 2010-year model

It's probably a Minn kota with a die hard label. Call Minn kota and ask them.
