Battery Cable: Description and Operation
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.
A clamping type female battery terminal made of stamped metal is attached to one end of the battery cable wire. A 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 slightly
smaller female battery terminal clamp.
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 for the location of more information on the
various wiring circuits included in the battery wire harness for the vehicle being serviced.
The battery cables connect the battery terminal posts to the vehicle electrical system. These cables also provide a path back to the battery for electrical
current generated by the charging system to restore the voltage potential of the battery. The female battery terminal clamps on the ends of the battery
cable wires provide a strong and reliable connection of the battery cable to the battery terminal posts. The terminal pinch bolts allow the female terminal
clamps to be tightened around the male terminal posts on the top of the battery. The eyelet terminals secured to the opposite ends of the battery cable
wires from the female battery terminal clamps provide secure and reliable connection of the battery cables to the vehicle electrical system.
The positive battery cable wire has an eyelet terminal that connects to the B(+) terminal stud of the Integrated Power Module (IPM), and an eyelet
terminal that connects the battery positive cable to the B(+) terminal stud of the engine starter motor solenoid. The battery negative cable terminal clamp
is attached to the ends of two wires. One wire has an eyelet terminal that connects the battery negative cable to the vehicle powertrain through a stud on
the engine cylinder block. The other wire has an eyelet terminal that connects the battery negative cable to the vehicle body through a ground screw in
the engine compartment.
