motor will not start (table saw) troubleshooting

Hi all,

Not sure if this is the correct place to post (new member),

 

I have an older  tablesaw (Jet, 1997 model) with a 1.5HP single phase, 120/240V (currently/originally wired 120), 18/9A,  3450RPM motor.

Will not start.

 

I have replaced the start capacitor and the thermal overload switch, with same value components.

 

Currently nothing happens. No noise, hum, etc.

 

When this started happening, I would hit the power switch and would usually get a slight pulse/bump where it appeared the motor was going to start but did not (could hear and physically tell the motor "jumped")

 

After about 10-15 times it no longer did that, so I suspected capacitor.

 

Other things I did:

- carefully blow out dust from motor, switch and thermal overload enclosure

- take front power switch apart to check connections

- verified motor shaft turns easily , not bound up

 

What would you check, suspect or try next ?

Thinking about yanking motor and and hooking up to a different switch and directly to power sans all the other stuff...

 

Any ideas greatly appreciated!
