DIAGNOSTIC BLINK PATTERNS (IGNITION RED
LED)
The diagnostic LED is located on the back of the igni-
tion control module, near one of the module mount-
ing bases. It will be necessary to remove the module
from the panel, and turn over, to view the LED.
• Normal Operation: LED flashes at a 0.5 second ON
and a 0.5 second OFF rate.
LED Fault Code with Priority as shown;
• No Crank Signal: LED blinks 2 times, is OFF for
3.0 seconds and then repeats
• No CAM Signal: LED blinks 3 times, is OFF for 3.0
seconds and then repeats
Only one fault is displayed at a time. If multiple faults
exist then the highest priority fault must be resolved
prior to a lower priority fault being displayed.
The diagnostic blink patterns provide flywheel and
CAM sensor diagnostics only during cranking follow-
ing the initial power-up of the ignition. The Generator
must have been in the OFF mode for 60 seconds
prior to cranking for the flywheel and CAM sensor
diagnostics to be valid (i.e. diagnostics are not valid
during a re-crank). The LED fault code blink pattern,
if present, is displayed for 60 seconds and then the
ignition will power itself down.
