5 Troubleshooting
If you are having issues with your controller, please refer to the table below for a solution before contacting technical support.
Issue Solution
Engine starts but the crank output
does not turn off The controller is not receiving a speed signal.
1. Verify the Sensors -> Engine Speed -> Signal Source setting is set correctly.
2. Verify the Timers -> Engine Logic -> RPM Disconnect setting is set correctly.
3. Ensure the correct wiring to the controller. For magnetic pickup, Speed
Sensing A and B terminals are used. For generator voltage, the AC voltage
connections are used.
Sensor always displays its lowest or
highest value The sensor could either be open (not connected) or shorted to ground. Verify your
connections and ensure the correct sender table is loaded.
Sensor value acts erratic, bounces,
or climbs on engine startup This could be caused by:
1. Bad ground between sensor and controller. Check that there is a good ground
between negative post on the battery and the battery negative terminal (J4-3)
on the controller. Also check that the connection from the negative post on the
battery to the sensor body is good; if not then add a grounding wire close to
the sensor.
2. The group strap is not sufficient AWG. Ensure the ground and power wiring
can carry the large amperage for the starter motor and other equipment.
3. If using a magnetic pickup sensor for speed sensing it might be generating
noise. Use a shield twisted pair cable from the mag sensor to the controller.
Refer to the typical wiring diagram on how to do this.
4. Try twisted pair cable running both ground and the signal; ground near the
sensor body. Try an isolated sensor (sensor has both a ground post and a
signal post).
Controller displays "Failure To Stop"
on a shutdown. Either set Energize to Stop under Timers to 0 seconds or increase it's duration. At the
end of the Energize to Stop time the controller will detect if the engine speed is zero. If
it is not it goes into a "Failure To Stop" failure.
