Delta 6" jointer not working - what next?
I went to buy a vintage B&D Workmate off CL this evening and before I left with the workmate the PO gave me a Delta 37-190 6" jointer. It looks to be in pretty good shape cosmetically. Doesn't look used & abused. Tables have minimal flash rust. He wasn't sure it worked and it appears it doesn't work after trying to turn the motor on once I got it home. Nothing when I hit the switch. I did notice when plugging it in that the ground prong had been snapped off inside the electric plug when I plugged it in. Question: Are these motors set up such that they won't work if the ground is missing? I'm skeptical about that but that would sure be the simplest fix. Anyway, just wondering how you guys would proceed trying to figure out if this thing is broken big time or just something simple?
PS I'll get some better pics tomorrow if needed.
Thanks, Mike

Checking switch step by step
Since you have a meter, might as well check the switch with it. You are correct about the green wires being ground. You will be doing the most basic test. Be sure power cord is unplugged, then unplug the two spade terminals on the back of the switch. Set your meter to one of the lower resistance settings, then touch the two probes of the meter together. You should get a reading on the dial. If not, replace the battery in the meter. Next touch one probe to each terminal of the switch. You should get a reading when the switch is in on poition and no reading in off position. If no reading in ON position, switch is bad.
If you have a bad switch, while the terminals are disconnected, you can take a short pcs of wire with both ends stripped, and push one end into each wire terminal making sure there is contact. Put a wrap of tape on and plug the power cord in. Motor should run if everything else is good.
