SECTION 10
ELECTRICAL COMPONENTS
10-1.ELECTRICAL CONTROL PANEL
10-1.1.Maintenance
NOTE:
Erratic operation of the truck may be caused
by defective controller components. Before
removing the electrical panel, perform trou-
bleshooting procedures per
SECTION 4 , to
determine corrective action to be taken.
There are no user-serviceable parts inside the control-
ler. No attempt should be made to open the controller.
Opening the controller may damage it and will void the
warranty.
The controller is programmed at the factory specifi-
cally for the truck model on which it is equipped. It is
important to replace the controller with the correct pre-
programmed unit to assure proper performance set-
tings intended for that particular truck. See
Figure 12-
14 for the preprogrammed controller number.
It is recommended that the controller exterior be
cleaned periodically, and if a Zapi Can Console kit and
laptop computer are available, this periodic cleaning
provides a good opportunity to check the controller’s
diagnostic history file. It is also recommended that the
controller’s fault detection circuitry be checked when-
ever the vehicle is serviced.
10-1.2.Cleaning
1. Turn off the key switch (13, Figure 10-2 ) and dis-
connect the batteries.
2. Remove the compartment cover as described in
paragraph
5-3.
3. Remove any dirt or corrosion from the bus bar
area. The controller should be wiped clean with a
moist rag. Allow it to dry before reconnecting the
battery.
4. Make sure the connections to the buss bars are
tight. Use two well insulated wrenches for this
task in order to avoid steering the buss bars.
10-1.3.Panel Removal.
1. Turn off the key switch (13, Figure 10-2 ) and dis-
connect the batteries.
2. Remove the compartment covers as described in
paragraph
5-3.
3. Tag and disconnect all electrical cables which
connect to the control panel (15).
4. Remove four screws (1), four lock washers (2),
four flat washers (3), and control panel (15).
10-1.4.Panel Disassembly.
Refer to Figure 10-3 for location and identity of the
major replacement components mounted on the panel
and remove defective parts.
NOTE:
Contactor (15) is not repairable and must be
replaced if defective.
10-1.5.Panel Installation.
1. Install the control panel (15, Figure 10-2 ) and
secure with four screws (1), four lock washers (2),
four flat washers (3).
2. Refer to Figure 12-15 thru Figure 12-16 and con-
nect all electrical cables to the control panel as
noted during removal.
3. If controller (1, Figure 10-3 ) was replaced, the
Vacc will need to be programmed as follows:
a. Connect the Zapi Can and start the Laptop
computer as described in paragraph
4-2.1.
d. On the ZAPI PC Can Console screen, click
on Program VACC. (See
Figure 10-1 )
