TESTING THE CHARGING SYSTEM
1. Connect the tester.
2. Start the engine and run it at 1200 to 1500 rpm. CAUTION: Stay clear of moving engine parts.
3. Note the meter reading with all of the electrical accessories off. It should be in the green "OK" band in the "charging system" scale (see illustration).
4. With the headlights and blower motor on high, the meter should remain in the green "OK" band.
5. If the meter reads in the red band or outside the charging system zone, trouble is indicated; most likely a defective alternator.

STARTER MOTOR TEST
This test identifies excessive starter current draw, which makes starting difficult and shortens battery life. Perform the battery load test first, to make sure the battery is in good
condition. If the battery tests either weak or bad, this test cannot be performed.
NOTE: The engine must be at a normal operating temperature.
1. Perform a basic battery load test. Note the exact voltage with the load test on (see meter illustration).
2. Using the load voltage obtained above, see Table 2 or the meter face, to find the minimum cranking voltage listed. If the engine is less then 200 CID, use the next
higher minimum cranking voltage. For example, if the load voltage is 11.00, use 10.2 for the minimum cranking voltage instead of 9.7.
3. If possible, disable the vehicle's ignition system so that it will not start. The test works best if the starter cranks for 2 to 5 seconds.
4. Crank the engine and note the voltage reading during engine cranking.
5. If the cranking voltage is below the minimum cranking voltage in Table 2, the starter current draw is excessive. If the starter cranks slowly, check for high resistance or
poor connections.
