BELT TENSION
On 2.2L, 3.1L, 3.8L, 4.3L, 5.0L, 5.7L, 6.5L Diesel & 7.4L engines, serpentine single belt tension is maintained automatically by a spring tension idler pulley. No adjustment is necessary.
OVERCHARGED OR UNDERCHARGED BATTERY
- If an overcharging condition is suspected, run engine at moderate speed. Connect voltmeter across battery terminals. If voltmeter indicates more than 16 volts, replace alternator.
- If an undercharging condition is suspected, disconnect 4-wire connector from alternator. Turn ignition on with engine off. Connect a voltmeter between terminal "L" in wiring harness and ground. (Схема №2) Record reading.
- If terminal "I" is used, connect voltmeter between terminal "I" and ground. Record reading. If voltmeter reads battery voltage, circuits are okay. If voltmeter reads zero, this indicates an open circuit between terminal checked and battery. Repair as necessary.
