You need to make up a test control. Get an old air conditioner fan switch and temp control. Figure out what is what on the switch and wire up the unit to that. On most rotary switches L2 stands alone with the fan neutral and the compressor neutral in the middle on the neutral bar. Then their is a L1 stand alone leg on one end of the rotary switch and 4 or 3 legs on the other end right. The compressor leg goes off to the temp control and then the other legs are simply hi med and low speed. So you connect a power cord to L1 and L2 and you connect the small black wire to hi small blue wire to med and the small red wire to low for fan speeds. The compressor has three wires on top of it. one wire goes to capacitor, one to neutral bar, and one to that temp control. Now you have a way to test it :D
