I have a Chicago electric 151 the old blue one. The problem is I was welding and took a break now the wire doesn't feed know, I can here the relay clicking and feel the motor humming at the reel. How do I determine if it's the relay or motor, the relay is part of the board my best guess would be run a jumper to the motor and see if it works? If it is the relay then I have to buy a new board for $70, a new welder for $170, or upgrade to something better for a little more cash.
