Champion winch failure
I have been borrowing my dads Champion 7500 lbs winch since the smoke came out of my old Ramsey. It was working good for about 5 years until I went to use it to pull a vehicle on a trailer. It would only engage the solenoids and not turn. I pulled the cap off the motor and found that the permanent magnets were broken. I've never tapped on the motor to cause this. It is stored inside when not in use.
I'm lucky that it did not fail while extracting myself out of a stuck situation.
