I have a Pro Source 1/3 HP, 2.6 Gallon, 120V, 2.5 amp, single phase portable air compressor that my brother asked me to try and fix for him. The model is 1126C and of course he dropped it, go figure. Anyway, this is the first place I could find any info. on Pro Source "Thank You very much by the way", and was hoping for some help. He does not have the wiring print for this unit and the three wires from the circuit board to the on/off switch came off. They are push on connectors and are colored red, black and yellow. The switch has three male connectors (A2, A, A1 The reason I list them in this order, is because that is the way they appear on the switch) with the connector nearest the ON position being either brass or copper and marked A2. I was hoping that this setup would be the same in other Pro Source compressors such as the 1113C. If anyone could help me with this problem, I would greatly appreciate it (and it would make me look like a hero to my brother lol). PS, I did call the 866 phone number but the customer service dept. was closed and I will try again tomorrow.
