I have a Husky Powerwasher and want to replace the capacitor. I see nothing on the capacitor terminals (nothing indicating a positive or negative charge) that tells me which one should be connected to the blue wire and which one should be connected to the white wire. Does anyone know?

They aren't polarized so it doesn't matter which wire goes where. Where did you get your cpacitor from though?

Hi,
There is a dedicated site with parts (Store) and online chat at:

Peace,
