4. Do the CHARGING SYSTEM TEST.
Does the display indicate voltage within 13.5-”15.1 V and amperage of 87.5 A or more? YES-Go to step 5.
NO-lf the voltage is less than 13.5 V, go to alternator control circuit troubleshooting (see page 4-28). If the voltage is over 15.1 V and amperage is less than 87.5 A, replace the alternator (see page 4-32) or repair the alternator (see page 4-34).
5. Check the diode condition on the display.
Does the display indicate GOOD? YES-The diode is OK.
