    I have a problem with our GMV Superstar when the main switch is in the off position the trap continues to windmill and has to be unpluged from the outlet to shut the trap off when in the on position it seems to be working normaly no windmilling. Is this caused by one of the 2 switches in the on / off box or is there some other switch that would cause this to happen.
    Thanks
    Steve.

    It is the piggy back contact on the main contact in the brain. Call Shyda's they have the part and new wiring diagram.(note: you must be able to read a wiring diagram.) A lighting strike will do this often

    This may have happened to another poster a while back . It may have been the switch itself . Also as stated , call Steve or Rod at Shyda`s in PA if thats who you do business with . They have always helped us.

    There are two electrical systems in your machine - one is 110 v, the other 24 v.

    The control for the arm release uses an electromagnet and is held in place by the 24 v system.

    When you turn your machine 'off' the 24v is in fact turning off and hence the arm is NOT held in place, but the 110v is remaining active ans allows your machine to cycle.

    This might be the switch itself (has it gotten wet??), or one of the relays in the power input portion of the machine (also sensitive to water). I would first try water displacing spray (WD-40, CRC-556) and heat (hairdryer) in both areas.

    Check the switch first(contacts inside switch may have some oxidation)clean them - if you have another machine try switching the switches - I've had this problem and it was the switch - J Mroczka

    Looks like it was a corroded contact on the switch from moisture. I cleaned it up and it works perfectly. Thanks all for the advice.

    Moisture is always the 2nd place to look on these. Micro switchs go bad also. All you need is an "open" and it will windmill. The adjustment of the micro switch being before TDC will also do it. We recently had one that gave us fits and it ended up being the wire that ran from the pull plug in to the trap house. It had moisture in it and someone used regular household wire instead of underground water resistant. Lots of things can cause it but it will always go back to something being open which means power all the time
