[PREHEAT] yellow LED
This indicator illuminates during the Pre-Glow cycle
(10 secs to 60 secs).
[ALTERNATOR FAILURE] red LED
This LED illuminates before engine starting or if a Belt
Break shut down occurs (than 20 secs).
[OIL PRESSURE] red LED
This LED illuminates before engine starting or if an
Oil Pressure shut down occurs.
[FUEL LEVEL] red LED
This LED blinks when a low fuel condition occurs.
This LED illuminates continuously to indicate a shut down,
if the switch has been closed for more than 5 minutes.

This LED illuminates when an High Temperature shut
down occurs.
[ENGINE RUNNING] green LED
This LED blinks for 15 seconds, indicating that the EP7 is ready
to start the engine (you have to turn the key to start). If the engine
does not run within 15 seconds, the "Starting Failure" alarm will
