Stator - Kohler 40COZ/33CFOZ Service Manual

7.6 Stator

Note: When replacing the rotor or stator, use a
skewed (slanted) rotor with a straight stator
per original manufacturer.
Stator Test Procedure
1. Check the generator output leads for proper
connections. See Section 9, Wiring Diagrams.
2. Check the stator windings for:
a. Shorted windings: Replace the stator if burnt or
hot windings exist. See Figure 7-12.
Note: Disconnect V7, V8, V9, and V0 leads at
the controller AC fuse terminal blocks
before performing the open winding test.
b. Open windings: With an ohmmeter, check each
pair of leads for low resistance readings
(continuity). High resistance across A or low
resistance (continuity) across B and ground
indicates a faulty stator; if so, replace the stator.
See Figure 7-13.
