Hi all. A friend of mine removed the faulty switch in his garden shredder, and it is now running backwards. There are only 2 wires going into the motor, and all he did was bypass the switch. I guess that there was more to the switch than just contacts, but what, and how does it work with an apparent single winding ?

What was the switch used for? Was it an off / on or forward / reverse switch?

Just on/off, I think. Either way, with just 2 wires going into the motor, what can be going on ?

By by-passing the switch I am assuming he tied the two wire together from the motor and if this is just off /on then it should work. However if this is forward / reverse and by tying the two wires together probably sent the motor into reverse mode.

Is this an electric or gas power shredder?
