• 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 specications.
Rotors and end bearings should be replaced as
a set. Replace rotor bearing support bracket if
old type. Contact Smith-Root, Inc. for further
information.
