the battery is less than 9.5 volts:
The battery is faulty
or
The charging system is faulty
or
The Megajector is faulty.

a. Connections - Check power, ground, and CAN
circuits at the Megajector in addition to all elec-
trical connections. Repair as necessary and
retest.

3.26 DEUTZ EMR 2 (S/N 85331 TO PRESENT)
The EMR2 consists of the sensors, the control unit and the
actuator. Engine-side controls as well as the JLG Control
System are connected by means of separate cable har-
nesses to the EMR control unit.
The sensors attached to the engine provide the electron-
ics in the control unit with all the relevant physical parame-
ters In accordance with the information of the current
condition of the engine and the preconditions (throttle
position etc.), the EMR2 controls an actuator that operates
the control rod of the injection pump and thus doses the
fuel quantity in accordance with the performance require-
ments.
The exact position of the regulating rod is reported back
and, if necessary, is corrected, by means of the control
rod travel sensor, situated together with the rotation mag-
nets in a housing of the actuator.
