[QUOTE="OnOff, post: 391807, member: 16173"] I've read about set ups with start and run capacitors whereby you can get sparking when the second capacitor is brought in and in effect you connect a charged capacitor across an uncharged. You get a high peak current that can cause sparking and sometimes welding of the contacts. To help they sometimes fit small resistors in series with either the start or run cap and use about 3 ohms per half horse power, 10W wirewound. Does it have a centrifugal switch is that working properly and dropping out the start cap? Big dose of contact cleaner! :lol: [/QUOTE]
