Im messin with the AC on my fummins project, I had the wires backwards with the diode in and kept blowin fuses. I took it apart to swap things around and had power the other day but now I cant get 12V to the compressor. Ive jumped the pressure switches, checked fuses and relays, I have a tach signal and cant get nothin when I had it the other day. Does anyone have a wiring diagram or know what I need to check? Thanks.
