Following the charging system at idle, press Enter for the charging system with
accessory loads. Turn on the blower to high (heat), high beam headlights, and
rear defogger. Do not use cyclical loads such as air conditioning or windshield
wipers.
When testing older models of diesel engines, the users need to run up the
engine to 2500 rpm for 15 seconds. The adjoining screen is displayed.
Press Enter to look for the amount of ripple from the charging system to the
battery. One of two of the following tests will be displayed together with the
actual test result:
RIPPLE DETECTED NORMAL
Diodes function well in the alternator / starter.
Or
RIPPLE DETECTED HIGH (Excess ripple detected)
One or more diodes in the alternator are not functioning or there is stator
damage. Check to ensure the alternator mounting is sturdy and that the v-belts
are in good shape and function properly. If the mounting and belts are good,
replace the alternator.
Press the Enter key to continue the charging system test with accessory loads.
One of the three results will be displayed along with the actual test result
measured.
ALT. LOAD VOLTS HIGH (when test with accessory loads)
The voltage output from the alternator to the battery exceeds the normal limits
of a functioning regulator. Check to ensure there are no loose connections and
that the ground connection is normal. If there are no connection issues, replace
the regulator of the alternator. Since most alternators have the regulator built-in,
this will require you to replace the alternator.
ALT. LOAD VOLTS HIGH LOW
The alternator is not providing sufficient electricity for the system's electrical
loads and the charging current for the battery. Check the v-belts to ensure the
alternator is rotating with the engine running. If the belts are slipping or broken,
replace the belts and test again. Check the connections from the alternator to
the battery. If the connection is loose or heavily corroded, clean or replace the
cable and retest. If the belts and connections are in good working condition,
replace the alternator.
ALT. LOAD VOLTS HIGH NORMAL (when test with accessory
loads)
The system is showing normal output from the alternator. No problem detected.
Press Enter when charging system test is completed to finish. Turn all accessory
loads and engine off.
Press the Enter key to get to the initial charging system test menu or remove the
test terminals from the battery to switch off the device.
