trolling motor help

ok the steady 12v wire is the power supply for the control board. That checks good!! The voltages you are seeing (4-12) are input voltages to the control board. The control board takes in the input voltages (4 being the slowest and 12 being the fastest) and then turns around and controls the "high" voltage going to the shaft motor. So if you are seeing a change in voltage then you are good up to that point!! So now you need to check the output voltage to the shaft motor. I would test in on the high setting and make sure you are getting your full 36 volts. If you are getting the proper voltage to your shaft motor, then you probably have bad magnets (or brushes, depending on how old the T/M is). Let me know what you find.

How do I check it at the shaft motor I got 38 volts going down the shaft or do
I need to check it on the motor itself. and if that where I need to check how the hell do I do that cant get the prop off must be a special way to open it.

Yes, unfortunately you have to check the voltage at the motor. You need a prop wrench to get the prop off. If you decide to get inside there yourself and you find water in there.............the motor will be shot since it sat in it so long.

Ok took apart motor there is a green circuit boad on the front of motor with a red and black wire coming from shaft 38 volts there ckecked also the two little magnets (i guess) both of them had 38 volts on them two. Now no water or rust in the motor on magnets but the was a little corrosion rust colored on the green board around where the red wire ties in the board also aroun the black wire too. Let me know if you need anything else thanks bayslayer for your help
