3. Connect the voltmeter (2) to measure between the
battery positive cable terminal clamp (1) and the
starter solenoid B(+) terminal stud (3). Rotate and
hold the ignition switch in the Start position.
Observe the voltmeter. If the reading is above 0.2
volt, clean and tighten the battery positive cable
eyelet terminal connection at the starter solenoid
B(+) terminal stud. Repeat the test. If the reading is
still above 0.2 volt, replace the faulty battery posi-
tive cable.
4. Connect the voltmeter (1) to measure between the
battery (2) negative cable terminal clamp and a
good clean ground on the engine block (3). Rotate
and hold the ignition switch in the Start position.
Observe the voltmeter. If the reading is above 0.2
volt, clean and tighten the battery negative cable
eyelet terminal connection to the engine block.
Repeat the test. If the reading is still above 0.2
volt, replace the faulty battery negative cable.
REMOVAL
The battery cables on this model may include portions of wiring circuits for the generator and other components on
the vehicle. If battery cable replacement is required, it will be necessary to extract the cables out of the engine wire
harness assembly. Use care not to damage the other wires and circuits which are also packaged into the engine
wire harness assembly.

BATTERY TRAY
DESCRIPTION
The battery is placed in a molded plastic tray (1)
located in the left front corner of the engine compart-
ment. The battery hold down hardware is contained
within the battery tray. (Refer to 8 - ELECTRICAL/
BATTERY
SYSTEM/BATTERY
HOLDDOWN

DESCRIPTION) for more information on hold down
hardware.
OPERATION
The battery tray provides a secure mounting location and supports the battery. On some vehicles, the battery tray
also provides the anchor point/s for the battery holddown hardware. The battery tray and the battery holddown hard-
ware combine to secure and stabilize the battery in the engine compartment, which prevents battery movement
during vehicle operation. Unrestrained battery movement during vehicle operation could result in damage to the
vehicle, the battery, or both.
REMOVAL
1. Remove the battery from the battery tray (1) (Refer
to 8 - ELECTRICAL/BATTERY SYSTEM/BATTERY
- REMOVAL).
2. Unlatch and remove the PDC from the battery tray
(1).
3. Remove the three nuts (2) that secure the battery
tray (1) to the weld studs on the front extension of
the left front wheelhouse inner panel.
4. Remove the battery tray (1) from the vehicle.
