ask:  have a motor that I suspect has a bad start and/or run capicitor and would like to repair it myself if possiable. This motor is used on a small air compressor. Thanks, Richard Answer: First make sure the capacitor is discharged.( Connect a large screwdriver across the terminals of the capacitor). Using an analog ohmmeter set to the 100K or 1000K scale,connect its leads across the capacitor, the ohmmeter needle should make a fas...

370V CBB65 Capacitor Metal Can Oval Case Run Capacitor

370V CBB65 Capacitor Metal Can Oval Case Run Capacitors   370V CBB65 Capacitor Description: The capacitor takes heavy-edge metallized Al/Zn PP film or web-like safety film as dielectric. The elements are tight winded by high-velocity winders and canned in aluminum cases. Refined castor oil is adopted as impregnation agent treated in vacuum and high temperature condition. Those make a more reliable performance and longer lifespan for a ...
