PROCEDURE 5:

CHECK STATOR WINDING - EXCITER RESISTANCES

• Check wire number tags. Label with tape and pen if missing.

• Cut wires at crimp connectors.

• Strip insulation back 1/4”

≈

(0.5 cm) to expose bare wire.

• Test winding pairs (1 & 2, 3 & 4, 5 & 6, 7 & 8, 9 & 10, 11 & 12,) (See

Fig. 5.1)

• Test yellow exciter wires (See Fig. 5.3) according to table below:

• Test 12 Volt winding pairs (White/White, Black/Black). Each should

measure

≈

0.1 Ohms (See Fig. 5.2).

• Check insulation of all windings to ground (open connection). (See

Fig. 5.4.)

• Replace Stator if out of specifications.
