CHAPTER 5
MODIFICATIONS TO VEHICLE ELECTRICAL SYSTEM TO PROVIDE
ELECTRICAL INTERFACE AND POWER TO HDC SYSTEM
SUBJECT:
Modifications to vehicle electrical system to provide electrical interface and power to HDC System.
DATE:
29 August 2008
DESCRIPTION:
Modifications are made to vehicle electrical system in several areas of vehicle to provide DC operat-
ingvoltageforHDCSystemandtoHDCsolenoidvalvesandpressuretransducersthatinterfacewithvehiclehydraulic
system assemblies and components.
Modifications to vehicle electrical system in driver’s compartment consist of adding a circuit breaker to the umbilical
cable disconnect bracket (installed in Chapter 2) in the front of driver’s compartment to control distribution of power
to HDC system, routing the application of HDC power through the existing parking brake relay, and routing/intercon-
necting an HDC power cable assembly (W1).
An upper cable assembly (W2) provides electrical interconnection between HDC components in the bowl area and
the HDC control box interface at the umbilical cable disconnect bracket.
A lower cable assembly (W3) provides electrical interconnection between HDC components in the lower forward por-
tion of the bowl area and on the underside of the vehicle, and the HDC control box interface at the umbilical cable
disconnect bracket.
TheHDCpowercableassembly(W1)provideselectricalinterconnectionbetweenvehiclepowerandtheHDCControl
Box interface at the umbilical cable disconnect bracket.
An umbilical cable assembly (W4) provides electrical interconnection between the three HDC cable assemblies in the
vehicle and the HDC control box (at the umbilical cable disconnect bracket).
