This will work if it is the Model with the Red Numeric readout on the dash (Engine RPMS and Low Fuel warning ETC)

With the Ignition off hold down the Cutter engage switch and turn the Ignition key on (Don't start the engine) until the headlights flash once.
Then turn off ignition.
This is the same as the 'K' series and was answerd by Nat
It works thanks Nat
