Engine Electronic Controller
The engine that is used in the Workman HDX uses an
electronic controller for engine management and also to
provide inputs for the gauge cluster on the machine. All
wire harness connections should be plugged into the
controller and engine electrical components before the
vehicle ignition switch is moved from the OFF position
to either the ON or START position. If the engine control-
ler or any engine components are to be disconnected for
any reason, make sure that the ignition switch is in the
OFF position with the key removed before disconnect-
ing the engine controller.

IMPORTANT: Before performing any welding on the
vehicle, disconnect the battery cables from the bat-
teries, disconnect the wire harness connectors
from the engine controller and disconnect the termi-
nal connector from the alternator to prevent dam-
age to the machine electrical system.
