I picked up a table saw(very large cast iron top) 5 hp single ph motor, has
a magnetic switch on it . It will run only when you hold in the start
button, shuts down as soon as you let go, tough to use that way... I
cleaned out the switch and box, checked for loose wires, found no arced or
burnt contacts , no difference. I have my trusty multi-meter and am ready to
troubleshoot as soon as one of the RCM electrical guru's rains a bit of
knowledge on me. What do I do next?

Thanks

Andrew


Check the continuity across the stop button contacts.
