Battery Cable: Description and Operation
Fig.17 Battery Cables - 4.0L Engine
Fig.18 Battery Cables - 4.7L Engine
The battery cables (Fig. 17) or (Fig. 18) are large gauge, stranded copper wires sheathed within a heavy plastic or synthetic rubber insulating jacket. The
wire used in the battery cables combines excellent flexibility and reliability with high electrical current carrying capacity Refer to Wiring Diagrams for
battery cable wire gauge information.
A clamping type female battery terminal made of soft lead is die cast onto one end of the battery cable wire. A square headed pinch-bolt and hex nut are
installed at the open end of the female battery terminal clamp. Large eyelet type terminals are crimped onto the opposite end of the battery cable wire and
then solder-dipped. The battery positive cable wires have a red insulating jacket to provide visual identification and feature a larger female battery
terminal clamp to allow connection to the larger battery positive terminal post. The battery negative cable wires have a black insulating jacket and a
smaller female battery terminal clamp.
The battery cables cannot be repaired and, if damaged or faulty they must be replaced. Both the battery positive and negative cables are available for
service replacement only as a unit with the battery wire harness, which may include portions of the wiring circuits for the generator and other
components on some models. Refer to Wiring Diagrams for more information on the various wiring circuits included in the battery wire harness for the
vehicle being serviced.
