present on the Pre-heat output of module. Check pre-heat has been selected in
your configuration.
Starter motor inoperative Check wiring to starter solenoid. Check battery supply. Check battery supply is
present on the Starter output of module. NB all the outputs are negative switching.
Fuel solenoid inoperative Check wiring to fuel solenoid. Check battery supply. Check battery supply is present
on the fuel output of module. NB all the outputs are negative switching.
Engine runs but generator will not
take load
Check that the output is working, NB all outputs are negative switching.
