Testing (On-Vehicle): Notes
NOTE:
Before making electrical checks, visually inspect all terminals for clean and tight connections. Check alternator mounting bolt torque and drive belt tension. DO NOT
ground the No. 2 lead wire. The battery must be in good condition to test the charging system.
CAUTION:
DO NOT
attempt to polarize alternator. DO NOT
ground any terminals except as instructed. Avoid operation with battery out of circuit or output terminal open. The alternator and battery share the same ground polarity.
