    Hi all I am a new member, not very well conversed in your world of circuits.
    I have a problem with my electric winch.
    I can hear the magnet take the brake off, but I have to spin the motor by hand to start it. It is the same in forwood and reverse.
    Can anyone help.

    Hello,

    I found your thread in the "feedback and suggestions" forum.
    That forum is NOT for question, so I moved it here.

    I am not to familiar with motors, but it sounds like a defective starter capacitor.

    Welcome to AAC !!!

    I'm guessing your winch is 12 v battery operated off your vehicle ?? if so, the brushes are likely making poor contact with armature commutator, due to being worn down, or normal accumulation of dust,.

    Hope your problem doesn't go as deep as a scorched commutator, you may be looking for a new winch

    Sorry I did not post the question properly.
    It is not 12 volt, it is 240 volt mains power.

    The capacitor holds charge, I discharged it but did not know how to test it properly.

    First order of business, would be to check the capacitor start and run. In the meantime, can you post any pictures ?
    specifically the motor nameplate, and inside the wiring box ?

    Does anything -- connections / wiring look burnt, or smell of charring / ozone, are any connections loose ?

    Sorry, I'm slow --- :D how much use does it see, weight does it have lift, and in what environment. It could be a failure of the start switch in the motor. though lets not get ahead of things and take too much apart.

    gotta go out awhile......will check back later............

    It is a PA600A cable hoist. 240 volt
    I have drawn as close as possible the wiring in my attachment.
    Thank you for your help.

    sounds like a bad centrifugal switch to me. But not sure why (other than being made in china) a winch would have a cap start motor.

    I wish I had seen your post Strantor before I drove 128 klm to Townsville to find out it was a faulty switch.
    I thank you all for your help.
