Troubleshooting Chart, continued
Problem ReferenceCorrective ActionPossible Cause
Light flicker Voltage stability (gain) setting Check and adjust the voltage
stability (gain) setting using the
ADC 2100.
Section 7.5.3
High generator
output voltage
Incorrect controller configuration Check and adjust the controller
configuration parameters.
Section 7.5
p
g
Incorrect controller voltage
settings
Check and adjust the controller
voltage settings.
Section 7.5.3
Engine speed too high Check the engine speed using
tachometer or frequency meter.
Adjust governor as necessary.
Section 4.4
Loose voltage sensing
connections
Check connections: stator leads
11 and 44 (for 1-phase models) or
leads 7, 8, and 9 (for 3-phase
models) and P15 controller
connection.
Section 8.7
SCR module Check the wiring and connections
to the SCR module.
Check the auxiliary winding fuse
F1 (lead 55).
Replace SCR module and test
voltage.
Section 7.7
Controller Check fuses, wiring, and
connections. Before replacing the
controller, replace the SCR
module and test voltage.

Section 7.11
No output
voltage
AC output circuit breaker open Check for AC voltage on the
generator side of the circuit
breaker. If there is AC voltage on
the generator side of the breaker,
then a problem in the load circuits
is causing the line circuit breaker
to trip. Check for and correct
short circuits or overloading on
the load side before resetting the
circuit breaker.

Alternator or control system Perform separate excitation
procedure to isolate the problem
to the alternator or the control
system. Then troubleshoot the
alternator or control system
components as follows.
Section 8.2
Aux. winding fuse blown (lead 55) Replace blown fuse. If fuse blows
again, check stator.
Section 8.12
SCR module Check auxiliary winding fuse F1
(lead 55).
Replace SCR module and test
voltage.
Section 8.12
Section 7.7
Controller Check controller settings. Check
wiring and connections. Before
replacing the controller, replace
the SCR module and test voltage.
