The black plastic capacitor is the compressor start capacitor, it is only in the circuit until the compressor gets up to speed. The black box is the start relay, it stays closed until the compressor gets up to speed the opens taking the start capacitor out of the circuit. The wires should go from it to the small metal round capacitor and the black box. You can Ohm out the start relay, it should be closed between Terminals 1 and 2 and the coil is from 2 to 5. You can also check the 2 capacitors, you need a Volt Ohm Meter that has a capacitor testing scale. The microFarads should be on the capacitors you will need to cut the bleed resistor on the start capacitor before testing it.

you have to change these like a window unit motor. remove cover to access
