Battery Inspection/Test - Side Terminal Battery
BATTERY INSPECTION/TEST (SIDE TERMINAL BATTERY)TOOLS REQUIRED
SA9154Z-A Starting and Charging System Tester
DIAGNOSTIC AIDS
IMPORTANT
- A dead battery is usually a symptom of another problem. Fix the problem, do not just charge or change the battery.
- Failure to properly understand the battery and its function could lead to a misdiagnosis and unneeded repairs. Refer to Battery Description and Operation and Battery Common Causes of Failure for more information.
Follow these instructions in order to avoid an incorrect diagnosis because of connections:
- If testing the vehicle with the battery cables still connected, wiggle the SA9154Z-A clips on the terminal bolt. This may cut through any coating or through any oxidation that may be present on the bolt. Even new bolts contain a protective coating that may insulate or cause a resistance in the test circuit.
- If correct connections to the battery terminal bolts in the vehicle are in doubt, perform the following steps:
1. Disconnect the negative battery cable.
2. Disconnect the positive battery cable.
3. Install the test adapters on the terminals.
- If the tester displays a "Bad Battery" result for a battery tested in the vehicle with the battery cables connected, perform the following steps:
1. Disconnect the negative battery cable.
2. Disconnect the positive battery cable.
3. Install the tester adapters.
4. Replace the battery only if the Out-of-Vehicle test shows a "Bad Battery" result. This prevents battery replacements that are due only to faulty battery cable connections.
- Use the correct terminal adapters.Do not use any common bolts or a combination of bolts, nuts, and or washers as adapters when testing the battery.Use the test adapters that are provided with the SA9154Z-A or P/N 12303040 terminal adapters. If the adapters that are provided with the SA9154Z-A require replacement, use P/N 12303040. Any other adapter may not contact the correct areas of the battery terminal, causing a resistance that may result in an invalid battery test result.
