Action
•
Ensure that the controller's output terminal is not directly connected to the starter
relay. The controller's output should be given to an intermediate relay which should
in-turn power the starter relay. The controller can get permanently damaged and
will need to be replaced if this precaution is not taken.
•
Check the start-relay connection with the suitable controller terminal.
•
Enter the Configuration mode in the controller and verify the configuration for Start
mode and the Start relay output polarity.
•
Check if the alternator voltage signal (L1 phase) is received by the controller
terminals.
•
Check if the LOP and LLOP are working OK, including the wiring to the controller.
•
Check the respective sensor and its wiring.
•
Enter the Configuration mode in the controller and verify the calibration for the
respective sensor in the configuration.
Check the wiring from the main alternator's L1 phase and neutral to the controller.
Check the wiring between the controller's terminal 41 (SCP) and the engine body
Enter Configuration mode, check if the Fuel analogue input configuration for the Fuel
sensor reference is like the physical connection. For example, if the configuration is
set as Battery negative the connection of the fuel sensor negative must be on battery
negative.
