| Symptom | Cause | Remedy |
|---|---|---|
| Annunciation output not working | Fault (short or overload) on one of the annunciator outputs | Check for fault, once fault is corrected then annunciation operation resumes. |
| Crank disconnect POT set too high | Decrease crank disconnect pot setting | |
| Engine cranks but does not start | Out of fuel | Check fuel level, add fuel if necessary |
| Engine does not crank | Battery is low or terminals are dirty | Clean terminals and re-charge battery |
| Engine starts and immediately goes into Over-speed shutdown | Over-speed pot setting too low | Increase Over-speed pot setting to desired value. |
| Engine starts but shuts down after “Oil BypassTM period” due to low oil/high temp/extra input wiring improperly connected. | Check wiring for proper connections. | |
| Engine starts, but running LED does not illuminate. | Improper speed range setting | Check to ensure that controller is set to proper speed range (DIP switches 4,5) |
| Fault (short or overload) on one of the annunciator outputs | Check for fault, once fault is corrected then operation resumes. | |
| Flashing Over-speed LED | Speed signal improperly connected, missing, or damaged. | Check speed signal wiring; |
