CHECKING THE STATOR POWER
WINDING
Access Requirements:
• Roof Removal ( Page 53 )
• Remove The Exhaust Bulkhead ( Page 53 )
• Remove The Blind-End Cover ( Page 56 ).
Related Fault Indications:
• Low Voltage
(FC_3)
or three remote blinks.
Gain access to the stator power winding leads as
mentioned above.
• Isolate the colored wires from the terminal block.
• Measure the resistance value of the stator power
winding as shown (Fig. 44).
Fig. 44 - Measuring Power Winding Resistance
If not:
• Check for short-to-ground.
If none:
• See “REMOVE THE STATOR ASSEMBLY” on
page 56.
If resistance reading is OK:
• Check for defective lead wire between terminal
block and circuit breaker.
• Re-assemble the standby generator enclosure.
CHECKING THE ROTOR WINDING
Access Requirements:
• Unit Disassembly ( Page 53 )
Related Fault Indications:
• Low Voltage (
FC_3
) or three remote blinks.
Gain access to the rotor winding leads as mentioned
above.
NOTE
: The rotor cannot be thoroughly
inspected without removing it from the generator
assembly. In addition, detailed components of
the rotor must be de-soldered in order to
determine its serviceability. For specific
instructions as well as general information about
this procedure
See “INSPECTING THE ROTOR
ASSEMBLY” on page 59 .
• Measure the resistance value of the rotor
windings and compare values to chart on
(
Page 64 )
If not within specifications:
• Check for short-to-ground.
If none:
• Replace Rotor
If resistance reading is OK:
• Re-assemble the standby generator enclosure.
In order to assist you in performing electrical checks, a
reference of the generator terminal block is provided
(Fig. 45).
