Table 5-2: Fault Isolation Procedures
FAULT PROBABLE CAUSE REMEDY
No AC output. Condenser failed. 1. Check condenser
NOTE: If you do not have measuring equipment,
install a known-good condenser. Start the
generator and check ac output. If the generator
ac output is normal, the fault was in the original
condenser.
2. Short the condenser leads across each other
to discharge the condenser.
NOTE: To make sure you get a good reading,
discharge the condenser before checking
capacitance.
3. Check capacitance of condensers (refer to
Table 5-1 for capacitance values for each
generator model). Replace condensers that
do not meet normal capacitance.
Stator fault. 1. Check Stator
2. Remove bolts (34) from front panel (32). Pull
the front panel (32) away from frame (44) (to
provide clearance for removal of control box).
3. Remove four screws (33) from front panel
(32) (to separate the control box [45] from the
front panel).
4. Locate the stator leads. Separate the leads at
the in-line connector.
5. Use an adhesive label or tag to identify the
leads (use the label or tag to make sure you
have the proper connection).
6. Measure resistance between the in-line
connector on the stator leads (refer to Table
5-1 for resistance values for each generator
model).
7. Replace stator if it does not meet resistance
values in Table 5-1.
