ZH
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. Refer to Wiring Diagrams for more
information on the various wiring circuits included in the battery wire harness for the vehicle being serviced.

OPERATION

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 for restoring 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 con-
nection of the battery cables to the vehicle electrical system.
The battery positive cable terminal clamp is die cast onto the ends of two wires. One wire has an eyelet terminal
that connects the battery positive cable to the B(+) terminal stud of the Engine Fuse Block, and the other wire has
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 die cast onto the end of one wire. The wire has an eyelet
terminal that connects the battery negative cable to the vehicle body through a ground bolt on the right front fender
inner shield, near the battery.
DIAGNOSIS AND TESTING - BATTERY CABLES
A voltage drop test will determine if there is excessive resistance in the battery cable terminal connections or the
battery cable. If excessive resistance is found in the battery cable connections, the connection point should be dis-
assembled, cleaned of all corrosion or foreign material, then reassembled. Following reassembly, check the voltage
drop for the battery cable connection and the battery cable again to confirm repair.
When performing the voltage drop test, it is important to remember that the voltage drop is giving an indication of
the resistance between the two points at which the voltmeter probes are attached. EXAMPLE: When testing the
resistance of the battery positive cable, touch the voltmeter leads to the battery positive cable terminal clamp and to
the battery positive cable eyelet terminal at the starter solenoid B(+) terminal stud. If you probe the battery positive
terminal post and the battery positive cable eyelet terminal at the starter solenoid B(+) terminal stud, you are read-
ing the combined voltage drop in the battery positive cable terminal clamp-to-terminal post connection and the bat-
tery positive cable.
VOLTAGE DROP TEST
The following operation will require a voltmeter accurate to 1/10 (0.10) volt. Before performing this test, be certain
that the following procedures are accomplished:
• The battery is fully-charged and load tested. Refer to Standard Procedures for the proper battery charging
(Refer to 8 - ELECTRICAL/BATTERY SYSTEM/BATTERY - STANDARD PROCEDURE) and load test proce-
dures (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/BATTERY - STANDARD PROCEDURE).
• Fully engage the parking brake.
• If the vehicle is equipped with an automatic transmission, place the gearshift selector lever in the Park position.
If the vehicle is equipped with a manual transmission, place the gearshift selector lever in the Neutral position
and block the clutch pedal in the fully depressed position.
• Verify that all lamps and accessories are turned off.
• To prevent the engine from starting, remove the ignition coil fuse. The ignition coil fuse is located in the Under-
hood Accessory Fuse Block, in the engine compartment. See the fuse layout label affixed to the underside of
the fuse block cover for ignition coil fuse identification and location.
