newbie used 2X4 method to start pump, need help on which contacts need cleaning.

[Poconos]

Don't know what kind of pump you have but they're all pretty similar. The pic is the rear end of a Hayward Superpump. Right in the middle you see a whitish spring, actually there is another one opposite, that's the centrifugal mechanism. You also see the switch assembly, the inverted V contacts. When the shaft gets up to speed the centrifugal weights fly apart and the mechanism opens the switch to disconnect the starter winding. Those contacts are what you need to clean. An automotive 'point file' or any thin blade file is best because it doesn't leave any grit residue, but you can also use a piece of 400 or 600 grit wet-or-dry sandpaper. Hardware or auto stores.
