Services Performed
- Confirmed the customer's concern and found the engine stalled. Using a multi-meter, measured voltage across the battery terminals and found voltage was below the specified range. Charged the battery, used a battery conductance tester to test the battery, and found the battery was able to conduct the specified amount of current. With the engine at idle, measured voltage across the battery terminals and found voltage decreased. Performed an inspection of the alternator wiring harness and connector, but detected 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. These test results verified the alternator was 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.
