Battery Cable: Description and Operation
Battery Cables - Description
DESCRIPTION
NOTE: Removing this isolating connector only disconnects power to the starter battery. If the vehicle is equipped with an auxiliary battery, that must
also be disconnected prior to vehicle service.
The battery cables 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.
The battery negative cable is routed out of the well to a isolating connector (1) on the left side of the instrument panel center stack, above the accelerator
pedal. When vehicle service requires disconnecting the starter battery this connector provides a convenient method of isolation. To disconnect the
connector pull down on the locking tab (2), and pull the connector (1) off the ground pin.
A 300 amp melting fuse is incorporated into the battery positive cable. If the fuse melts, the battery positive cable must be replaced. The main reason
this fuse would melt is from reversing polarity while jump starting the vehicle.
The battery cables feature a stamped brass clamping type female battery terminal crimped onto one end of the battery cable wire and then solder-dipped.
A square headed pinch-bolt and hex nut are installed at the open end of the female battery terminal clamp. The battery positive cable also includes a red
molded rubber protective cover for 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 positive cable wire harness or the battery negative cable wire harness, which may include portions of
the wiring circuits for the generator and other components on some models.
