12) Put Compressor at load condition after 3 to 5 minutes of normal operation. Use the capacitor discharge tool (Figure SP-8-6) to discharge citor and any other capacitors in the unit. This is only for checking the compressor to see if it's good or not (if it starts or not). If you have been using the compressor for a long time, this could be the possible reason. 05) Check the position of safety shut down switches. I checked the capacitor and it would not hold a charge so I replaced it with a SUPCO RO81 convinced this was the problem, but still no go. If air is trapped over the piston on the air compressor, that adds load to the start circuit. Then, plug in the air compressor, turn it on, and wait for the needle on the pressure gauge to stop moving. I don't have a tech sheet for that model but I don't need one yet. Pay me now or pay me later be remember later will cost you more. If found any leak, rectify immediately. voltage is applied directly across the main coil, and in series with 45uF 450V capacitor to the other coil. Don't know if I'd recommend this.

Actually, the motor requires a lot of power to start … Your 120 volt power supply hasn’t got enough oomph to start the motor without help from a start capacitor anyway, and that additional load on the compressor motor is typically sufficient to prevent the air compressor from starting. If a starting capacitor is used, then a relay with two ter-minals is required (see Figure 3). On other jet engines, a small gas turbine is used to blow hot combustion exhaust through the main turbine, which spins the main compressor up to … Each year, the compressor manufacturer's receive numerous field returned compressors that apparently have failed.
