I have a brute 567 12/24 volt hand trolling motor... it was working fine yesterday and now it wont even turn on.... is it bad wiring plug???? cuz the battery is fully charged

do you have it hard wired to pos and neg or does it have the 3 prong plug in switch ..if 3 prong its for a 24/36 volt motor wont work on 12 volt less you have the 12 volt plug

You have a high resistance short either inside the wiring or the lower unit. This will cause a voltage drop. I would be very careful not to keep it connected too long cuz the battery is trying to keep up with the current demand and may explode.

I believe you may have a bad low voltage circuit board problem. I do not think they make the board any longer but you may be able to convert it to work by bypassing the circuit board. I am working on one now.

i think its time to strip this motor out,, it sounds like its has a short in the field coil winding,,as its pulling far to many amps,,,,

Just got parts 4 my 96 brute from trolling motor parts .com

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.

What I would do is pull the fan blower motor speed switch, plug the wires back into it while you're holding it in your hand, run the car, and check with a multitester and see if you are getting voltage at the switch. Should be something like:
High=12-14 volts
MHi=8-10 volts
MLo=4-6 volts
Low=2-4 volts
OFF=no voltage

If you get voltage but the fan still doesn't work, then it's either a bad ground, or the motor is bad. If you can access the blower motor wire connections(sometimes its easier to try this with it removed from the vehicle), then you could try jumping the blower motor at the wiring connection with a known good 12 volt source, and if you STILL can't get the motor to spin then it's seized up or it's just a bad motor. If you have the motor removed, try spinning the squirrel cage by hand. Is it stiff? Seized? Probably need a new one if it doesn't spin freely by hand.

Hope this helps!

The white wire is the ground. The black wire is neg. and the red wire is pos.

you will probably find it is either a switch problem or your wiring this is a twist handle?
