• If the first sensing wire does not have continuity, replace the sta-

tor.

• If the first sensing wire has continuity, continue.

4.17.6 Check the first sensing wire for a short to ground. (Measure resistance

between the wire and the ground stud of the stator.)

• If the first sensing wire has resistance to ground, replace the sta-

tor.

• If the first sensing wire has no resistance to ground, continue.

4.17.7 The second sensing wire is really a circuit. It is represented by the blue

wire and then the brown wire on the electrical schematic. This sensing

circuit runs back through the Voltage Selector Switch (VSS) where the

wiring splits, with one wire running to main winding 1, another to main

winding 2. The circuit is accessed by disconnecting the plug (d) from

the connection point at the lower end of the stator. To check the circuit,

first check the main-winding-2 side. To do so, place the VSS in the

120V position. With one lead of your multimeter, probe the blue wire

(e) of the plug. With the other lead, probe the generator terminal strip

(f) where the red-marked wire is usually connected. There should be

continuity.

Next, check the main-winding-1 side. To do so, place the VSS in the

120V/240V position. With one lead of your multimeter, probe the blue

wire (e) of the plug. With the other lead, probe the generator terminal

strip (g) where the black-marked wire is usually connected. There

should be continuity.

• If the second sensing wire (circuit) does not have continuity,

check the wiring through the various connectors and the VSS.

Repair or replace components as needed.

• If the second sensing wire (circuit) has continuity, continue.

4.17.8 Check the blue wire for shorts to ground. (Measure resistance between

the wire and the ground stud of the stator.)
