Fw: Re: [GreenKeys] Western Union Motor Control Relay ?

[Wayne Letourneau]

The "strange" heavy relay mounted horizontally is a "Polar" relay. Is used
in the line circuit and has nothing to do with motor control.

Jim, 
 
My WU machines have a very "strange" heavy relay mounted horizontally in the

Rear of the machine. I'll get a pix of it and send. The contacts are no 
Longer connected and appear large enuf to handle motor current. It's next 
To a screw in fuse.
