Hi Joe,

Here is the information for you to test your two switches. Hope this helps.

B to F1 (-28 Ohms {Resistance Through Switch Resistor})
A to F1 (-28 Ohms {Resistance Through Switch Resistor})
B to A (0 Ohms)
F2 to Chassis Ground (0 Ohms)

Medium Speed Position:
B to F1 (-10 Ohms {Resistance Only Through Dash Harness Brown* Wire via R1})
A to F1 (-10 Ohms {Resistance Only Through Dash Harness Brown* Wire via R1})
B to A (0 Ohms)
F2 to Chassis Ground 0 Ohms

Low Speed Position:
B to F1 (0 Ohms)
A to F1 (0 Ohms)
B to A (0 Ohms)
F2 to Chassis Ground (0 Ohms)

OFF position:
B to P (0 Ohms)
A to F2 (0 Ohms)
F1 to Chassis Ground (0 Ohms)

Internal Circuit Breaker:
B to B/U (Always 0 Ohms Regardless of Speed Selection or Off)
