through 10A fuse [No. 14, located in the fuse block (J/B)] to combination meter terminal 22 for the charge warning lamp.
Ground is supplied to terminal 14 of the combination meter through terminal L of the generator. With power and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient volt- age with the engine running, the ground is opened and the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a fault is indicated.

Trouble Diagnoses with Battery/Starting/Charging System Tester NOTE: To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done as a set from start to finish. 1. Turn off all loads on the vehicle electrical system. 2. Perform battery and starting system test with Battery/Starting/
EKS008L8
Charging system tester.
3. Press “ENTER” to begin the charging system test. 4. Start engine.
5. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC” is dis-
played.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle. Once the increase in engine rpm is detected, press “ENTER” to continue. NOTE: G If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.
G Some engines may have a higher idle initially after starting, particularly when the engine is cold. The tester may detect this without any other action being taken. If this occurs, con- tinue on with the testing process. The final results will not be affected.
7. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the follow-
ing electrical loads. G Heater fan set to highest speed. Do not run the A/C or wind-
shield defroster.
G Headlamp high beam G Rear window defogger NOTE: Do not run the windshield wipers or any other cyclical loads.
9. Press “ENTER” to continue.

10. Raise and hold the engine speed at 1,500 to 2,000 rpm for about 5 seconds, then return the engine to idle. Once the increase in engine rpm is detected, press “ENTER” to continue. NOTE: If after 30 seconds an increase in engine idle speed is not detected, “RPM NOT DETECTED” will be displayed. Press “ENTER” to restart the test.
11. Diagnostic result is displayed on the tester. Refer to SC-24,
"DIAGNOSTIC RESULT ITEM CHART" .
12. Press “ENTER” then test output code is displayed. Record the
test output code on the repair order.
13. Toggle back to the “DIAGNOSTIC SCREEN” for test results.
