Battery Testing & Inspection
NOTE:
Before testing battery, lightly tap eye of hydrometer to ensure that gas bubbles have not lodged themselves in hydrometer. If battery needs replacement, check charging system for proper operation. DO NOT charge a battery with a clear or Yellow indicator. See BATTERY CONDITION INDICATOR
.
BATTERY CONDITION INDICATOR
| Hydrometer Indicator | State Of Charge | Required Action |
|---|---|---|
| Green | Above 65% | Load Test |
| Dark | Below 65% | Charge Battery |
| Clear Or Yellow | Low Electrolyte | Replace Battery |
- Inspect fusible link for damage or discoloration. Test for battery voltage on both ends of link. Replace with same size fusible link. The wire-gauge size is printed on insulation.
- Inspect vehicle for theft deterrent system(s).
- Inspect positive and negative battery cables. Inspect ground circuit cables. Inspect starter assembly connections. Test ignition switch for proper operation.
- Inspect accessory drive belt tension and condition. Verify generator-to-engine block bolt torque. Test fusible link in circuit between generator and starter. Verify battery cable and terminal connection.
- During engine start-up the instrument panel cluster performs a bulb check by illuminating the telltale for 3 seconds. If a code setting condition occurs, the ECM (3.0L) or PCM (2.2L) signals the I/P cluster to illuminate the charge telltale. The ECM communicates with the I/P cluster by Class II on circuit No. 1807.
