I'm attempting to salvage an extinct Campbell Hausfled air compressor (pics attached). According to the labeling it's an industrial unit with a 7.5 hp peak motor. I've got the motor working (ish) but I need to verify the wiring and replace the centrifugal switch, probably with an electric switch, the issues are I'm just a hobbyist, the unit is obsolete and there is NOTHING to be found online, and as I have figured out there's really not a wiring color code concerning the internal wiring. I would be most appreciative if anyone could share some pictures, an actual repair manual would be awesome. I'd like to keep this thing out of the dump, any help would be greatly appreciated.
