I want to try to discribe the diagram, because it is somewhat like
Brian's explenation but not exactly.

Wire 2 is half the main winding which connects to internal wire 1
(pink) Wire 5 is half the start winding with the capacitor and a
discharge resistor across the cap. in front of the winding. This also
connects to wire 1.

7 and 6 are the 2 halves of the cent. switch

wires 3 and 4 come off the thermal protector 3 comes out of P1 and 4
comes out of P3 there is a P2 but the diagram does not show a
connection.

Wire 1 goes into P3.

wire 4 is indicated on the diagram as Cust Signal Lead (hand written)

in the lower left labeled For test

Line into 3
5 & 6 jumpered
Line into 7 & 2 which are Jumpered
