I need some help, folks. The capacitor on my 50-720 Delta dust collector melted down over the weekend. It is such a loss that I can't read any of the numbers on the can. I have searched everywhere on the machine, in the manual, the internet, and also called Delta. I can't find a mfd rating anywhere. I found another Chinese 1HP, 115V, 3500rpm motor that had a start capacitor with a 270 mfd rating, so I picked up a similar capacitor from Grainger. When I installed the capacitor, the motor would start, but wouldn't reach full RPM. If I left the motor to run, it would slow down until it popped the breaker.
Anyone have any idea what start capacitor rating this thing uses? I would really like to avoid pulling the motor and taking it to a shop. The motor does work. Without the capacitor, I can give the motor a good spin, flip the switch, and it will start up. It takes an extra second or two to reach full RPM, but it does and will hold the RPMs.
Many thanks.
Regards,
Ken
