Dual Fuel Engine Warning Light
This light is for operator inspection upon powering the
system with the ignition switch. This light displays error
codes, if present, when the ignition switch is turned on,
engine off. The codes are conveyed by flashing the light in
such a manner that the first numeral flashed, a pause, and
then the second number if the code flashed.
The light will flash a code 12 every time the ignition switch is
moved to the ON position; this indicates the system is in the
diagnostic mode. When a code has been set, the code will
be indicated after the code 12 is flashed. For instance, if a
code 24 has been set, the light will flash one time, pause,
flash two times, after which it will flash two times and then
four times, indicating the code 24. If multiple codes are set
they will be displayed in numerical order, not in order of
occurrence.
