Important!
Check that the battery is completely charged (if necessary recharge it with a battery charger) and disconnect all of the car’s loads (radio, lights, A/C, etc.), except for those necessary for engine operation.
• Lift the vehicle on the car lift and connect a voltmeter and a 150A or higher ammeter clamp onto the alternator’s
output cable:
Voltmeter “V” and ammeter clamp “A” connection (Fig.4)
A. Battery
% Junction
C. Starter
• Start the engine and bring it to 2,000 rpm.
• Using the voltmeter, check that the voltage generated by the alternator falls within the values in the chart
( Fig.5 ).
• Using the ammeter clamp, check that the alternator supplies current. This current might initially be very high
(100A at 2,000 rpm) but then gradually decreases as the battery recharges. The current depends on the engine’s speed ( Fig.6).
