I recently acquired a used Spa Pump motor. I would like to use the motor for something in my woodworking but need some info regarding how to wire it up.
You will need a single pole double throw switch capable of handling 20 amps. A place like Home Depot or most hardware stores will have this. You can get one that looks like a standard wall switch or one that fits through a 1/2 inch hole in a metal panel.
#2 goes straight to one of the lines. #3and #4 go to the switched leads on the switch. And the other line goes to the un-switched lead on the switch.
If you use the smaller switch that goes through a 1/2" hole, the switched leads are on the ends and the line goes in the middle. If you use a wall type switch, you can mount it in a handy box from the hardware store. the three screws are two different colors. The #3 & #4 go to the same color screws and the line goes to the other color screws.
The colors will probably be silver and brass.
Hope this helps you. Robert

Sir, I had a problem with my 1000kVa diesel engine
The injectors probably were damaged because the unti ran away, it should have shut down on over speed. If it did not then the sensor and control need checking. I would also check the engine oil to see if diesel has found its way into the sump. If it has then the rings are shot and the unit is "self feeding" off it's own engine oil, and no control signal will shut it down, it needs checking out by a pro, as a runanway diesel is extrememly dangerous in the size you are speaking !
