Default DoAll DBW-8 Bandsaw blade welder whoas

Well, I went out the other day to make the new anvil stand for the Refflinghaus anvil and I turned the power on the bandsaw and heard a strange noise by the welder.

I listened and it sounded like gear noise. I then went to weld a new blade with no luck.

I then opened it up and the gear drive motor is just spinning away with no power going to it.

It uses power from the anneal switch to power the unit. But when I detach the wire connected to the power distribution it continues to run.

Power to the anneal switch is constantly on. But what would power the motor or what would keep the motor just spinning around?

there is no switch per se. When the power trips after a weld the motor used to stop. It also started once the weld button was pushed. To jog it I could just push the weld button to bring it back into position.

What would keep it running? A short internally? I tested the outside to the chassis and no voltage. I checked the wire that connects to the power distribution and it was 0volts.

the yellow wire is the connection to the motor. I think it might have been replaced previously years and years ago as the tape on the motor itself looks like original.

If I defend myself I am attacked.

My meaningless thoughts are showing me a meaningless world.

My attack thoughts are attacking my invulnerability.

I'd like to think of something smart, but I don't want to hurt myself.
