Sir nameuser . . . . .
Usually you don't see anything coming from a dry electrolytic unit like that, unless they explode.
Usually, failure analysis reveals just a time related gradual drop in capacitance to the state where it can no longer provide its start up boost. That motor is being of 1989-90 vintage.
Does the unit even hum at all on power up.
If hummee-hummee, have the motor housing supported solidly. Then take a venetian blind size cord and wrap it around the motor shaft as many turns as it can take , keep it taut, then pull heftily on the cord to get a good spinning while immediately powering up the motor to see if it runs with that mechanical spinnng start. (50/50 chance that you
MIGHT have wrapped the cord around in the wrong run direction . . try- try again ! )
If you then have a running motor, the replacement capacitor spec is a minimum 850 ufd at a preferred 125 V rating.
The reason why you want to do that pre testing . . . . . .because thats a Buuuuuuunch 'o mammafarads ! and thusly . . . . .being priced accordingly.
