I have a 2nd hand 36-825 Unisaw that has worked great for years. Yesterday the saw started for less than a second, then stopped. The blade turns freely. There is power all the way to the switch. It does not appear there is a "reset" button on the motor itself. I'm hoping it's the switch and not the motor. The on/off switch appears to be original. I'm sure this switch, 438-01-016-0194, is no longer available. Any suggestions on how to test the switch with a volt/ohm meter? Thanks in advance.
