11. Immediately after setting the headlights to high beam and turning the heater
blower switch to the highest position, increase the engine speed to 2,500 RPM
and read the maximum current output value displayed on the ammeter. Limit
value: 70 percent of nominal current output.
12. The reading on the ammeter should be above the limit value. If the reading is
below the limit value and the generator output wire is normal, remove the
generator from the engine and check the generator.
13. Run the engine at idle speed after the test.
14. Turn the ignition switch to the LOCK (OFF) position.
15. Disconnect the engine tachometer or scan tool MB991958.
16. Disconnect the negative battery cable.
17. Disconnect the ammeter and voltmeter.
18. Connect the negative battery cable.
19. Run the engine for 10 minutes at an idle. REGULATED VOLTAGE TEST Required special tools:
MB991958: Scan Tool MUT
-III Sub Assembly.
NOTE: The current output value will depend on the electrical
load and the temperature of the generator body.
NOTE: If the electrical load is small while testing, the specified
level of current may not be output even though the
generator is normal. In such cases, increase the
electrical load by leaving the headlights turned on for
some time to discharge the battery or by using the
lighting system in another vehicle, and then test again.
NOTE: The specified level of current also may not be output if
the temperature of the generator body or the ambient
temperature is too high. In such cases, cool the
generator and then test again.
