- Confirmed the customer's complaint and found the engine stalled when driving. Performed an underhood inspection and found the drive belt was glazed. Inspected the battery and the battery cables and found no faults. Used a multi-meter to measure the voltage across the battery terminals and found the measured voltage was below the specified range. Used a battery conductance tester to test the battery and found the battery was able to conduct the specified amount of current, which verified it operated properly. Performed a visual inspection of the alternator and found no obvious faults. Used an alternator load tester to test the alternator by placing the battery under load, raised the engine speed to 1,500 RPM, and found the measured alternator output was below the specified minimum amperage. Off idle, used a lab scope to measure the AC ripple in the charging system by connecting the lab scope leads across the battery terminals. The AC ripple observed on the lab scope was above specifications. These test results verified the alternator and the drive belt were faulty.
- MAKE SURE ALL WIRES ARE INSERTED INTO PROPER CAVITIES. RE-ASSEMBLE BACK TOGETHER. CONNECT BATTERY. MAKE SURE ALL OTHER WIRES ARE HARNESSED PROPERLY. TEST ALL AFFECTED SYSTEM.
