7 Fault Finding, generator General
Fault Finding Table
When a fault occurs, check the following before carrying out the tests
in the Table:
• The circuit breaker is ‘ON’.
• The generator has not suffered any mechanical damage.
• It has not been affected by spilt oil, fuel, dirt or chemicals. If this is the
case, clean or repair this before starting testing.
• The voltage regulator has not been exposed to water. If the regulator
is wet, remove it from the connector box and dry thoroughly before
refitting.
1 No load, no voltage
Possible fault Remedy
Voltage Regulator (AVR) faulty. Replace the Voltage regulator
(AVR).
Loss of residual magnetism. Connect a 12 Volt battery for a
short period to regenerate the
field; plus (+) to EXC. + and minus
(-) to EXC. -.
Stator winding short-circuit or
poor connections. Check the winding resistance.
See ‘Technical Data’ for resistance
values.
Rotor windings short-circuit or
poor connections. Check the winding resistance.
See ‘Technical Data’ for resistance
values.
Short-circuit in on-board circuit. Trace the short-circuit and repair.
