Electronic Engine
The mid-range machine contains an emissions certified diesel engine. In order to meet the
emissions requirements, the engine has an electronic control system.
The control system handles all monitor, alarm and control functions for the engine. The
WEDGE controller communicates with the engine controller over the J1939 CAN network.
J1939 Data Link
The CAN network is a single pair shielded cable located with the W1 main harness. Figure 2-
3 shows a layout of the CAN harness or "backbone" as it is referred to. The termination
resistors (Terminator) are important to prevent reflections on the transmission line and must
be in place for the network to function properly. The shield from the cable is connected to the
machine metal at the WEDGE controller end.
This connection must be properly made with good metal-to-metal contact between the wire
terminal and the machine metal.
The engine diagnostics connector is located on the left side of the engine. This is used to
connect the engine manufacturer's service tools to the CAN network. This connector also
provides 24 VDC to power these service tools.
Electrical System
The electrical system consists of the wiring harnesses and associated electrical devices such
as relays, switches, lights, solenoids and alarm horn. There are two wiring harnesses in the
mid range machine. They are as follows:
22801021 W1 Chassis Main Harness
22108690 Control Panel Harness (Before S/N 375132)
22817829 Control Panel Harness (After S/N 375131)
The schematic diagrams show the connections for these harnesses. Figure 2-1 is a system
schematic showing harness connection with devices and controllers.
The electrical circuits are protected using ATC style fuses. A fuse should only be replaced
with one of the same rating. Replacing a fuse with one of a large rating could lead to harness
damage. If a fault occurs and the circuit does not have the appropriate size fuse, wires could
be burned in the harness and damage other circuits.
