Wiring motor/switch help...Please

**RRR** · 11-07-2019, 10:21 AM

here are two schematic drawings of a single phase dual voltage ,capacitor start motor with centrifugal switch . both drawing's are the same motor ( though id give you two versions of it )your motor is a variation of this motor. This should help you in identifying the motor windings ,so that you can arrange them how ever you need to . I would suggest that you use analog or digital meter ( Simpson 260 //or a fluke multi meter or similar ) both main motor winding sets 1 &2 ,3 &4 should ohm the same resistance ,the start winding will ohm significantly higher than the run winding . note or tag leads after ohming ( I think you'll find the existing color code ( see previous pic ) to be NEMA standards .

1. on the back of the board, switch the locations of the yellow and orange wires.
2. on the front of the board, move the white wire with the ring terminal to T4.
3. on the front of the board, move the red wire to T5.
4. on the front of the board, ensure the line-in wires from the switch are on T1 and T3.

Everything else should be as my earlier drawing.

Oh, and i'd put a couple big permanent marker 'X' marks over the motor wiring diagrams

Eureka ! ! That worked

Thank you very much, Allan, you certainly know what you are talking about

Thanks again,
Ted

LOL! May I rcommend, then... purchase of a vintage top of the line "Monroematic" motor-driven electromechanical "desk" calculator?

Needs a fair stout "desk" under it, but should keep you out of pubs and brothels for easily a full week, if not a whole month!

BTDTGTTS!
