Starter/Generator
Testing of starter/generator field and armature windings
is difficult with the starter/generator still mounted in the
Workman. Follow the procedures for Starter Generator
& Voltage Regulator Component Testing prior to remov-
ing the starter generator for further testing and repairs.
Starter generator resistance tests are as follows:
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5 ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from the measured value of the component you are
testing.
1. Measure resistance (Ohms) between starter gener-
ator terminals DF and F1 (field). The meter reading
should be 5.5 to 5.9 Ohms.
2. Measure resistance (Ohms) between starter gener-
ator terminals A1 and A2 (armature). The meter reading
should be under 1 Ohm.
3. Measure resistance between each terminal (Fig. 12)
and ground. The meter reading should be infinite.
4. Starter/generator disassembly and repair will be
needed if readings are incorrect.
