I would like to ask for your input in troubleshooting my older Simpson Lawrence
Horizon 1500 windlass
A few months ago, the windlass
started to show symptoms of struggling during operation. The motor
speed goes down, in either direction, and I can see on the battery
meter that the amps being pulled goes higher during these moments of struggling.
Finally (as expected) she fully quit working.
I have dismantled the motor
to find out that the armature wiring
melted and burned.
I took it to a workshop to re-wire, and replaced the four carbon brushes
She got back in action, working better than ever. After only 3-months of light operation, she started to show the same symptoms of struggling.
I, again, removed the motor, and my first observation was that at least one of the brushes
was somehow not moving freely in it's housing (as if it's somehow sticky inside the brush housing - which I remember cleaning
using a degreaser before putting in the new brushes).
Based on this final observation, I am guessing that one or more brushes stop moving freely, and this puts an extra load on the motor to turn. She starts to pull in more amps to rotate, gets too hot and damages the armature wiring
Any remedies, or any other input would be highly appreciated!!
I am stuck
