I need help with my pump motor. It works fine on low. When I try to switch it to high it just jerks in and out like it is trying to start but can not. I pulled the cover off the back of the motor and I can not find a start capacitor. The motors model number are not legible anymore. From what I can find it is a Jacuzzi pump with a Magnetek motor. The motor is rated at 8.8/2.6 amp but I can not find much else on it. Anyone have any ideas? Thanks for any help.
