4.2L IGNITION DESCRIPTION
This single-fire ignition is intended to operate a 6-cyl-
inder, 4.2L, 1800rpm ignition. The 4.2L engine uses
a 36-1 crank sensor, a CAM sensor and coil-on-plug
coils for each spark plug. Engine Timing for the 4.2L,
1800rpm engine is 15 degrees BTDC for both LP and
NG.

The Cam Sensor is factory set to the FULL coun-
ter-clockwise position. Tampering with the posi-
tion of the Cam Sensor could result in engine
failure.
IGNITION POWER-UP INPUT (“56 LINE INPUT)
‹
When battery voltage is applied to this input the igni-
tion will power-up. For the ignition to power itself
down, the battery voltage must be removed from this
input.
DIAGNOSTIC BLINK PATTERNS (RED LED)
‹
During normal ignition operation the RED LED,
located on the ignition control board, flashes at a 0.5
second ON and a 0.5 second OFF rate. This is con-
sidered one (1) blink.
RED LED Fault Codes with priority as shown:
1. Ignition cannot initialize: LED is ON continu-
ously during cranking.
2. Engine Overspeed: LED blinks four (4) times, is
OFF for three (3) seconds and then repeats.
3. No Crank Signal: LED blinks two (2) times, is
OFF for three (3) seconds and then repeats.
4. No Cam Signal: LED blinks three (3) times, is
OFF for three (3) seconds and then repeats.
Only one LED fault code is displayed at a time.
If multiple fault codes exist then the highest priority
fault must be resolved prior to a lower priority fault
code being displayed.
The LED fault code blink pattern is displayed for 60
seconds after a fault and then the ignition will power
itself down.
The Generator must have been in the OFF mode for
60 seconds prior to cranking for the Crank and CAM
LED fault diagnostics to be valid.
The Crank and CAM LED fault codes are not valid
during a re-crank.
NOTE:
The ignition cover does not need to be removed to
see the RED LED
