only 12V systems. Checking 24 or 36V systems will damage the charger.
The ALTERNATOR VOLTAGE CHECK measures a defined range of voltage that is available from the
fully charged battery. The user must allow the engine to warm to normal operating temperature and
achieve a normal idle speed. As many appliances as possible are turned off for the first part of the check
to allow the battery to reach it*s highest voltage level.
The ALTERNATOR VOLTAGE CHECK is only activated after 10 to 30 minutes of engine idle. if the
ALTERNATOR GOOD LED lights, then the ON/OFF button is pressed to stop the check. Alternator
Check is then repeated after many appliances are turned on to check the alternator output under a
greater load, if the first (unloaded) and second (loaded) checks indicate the alternator is good, then the
entire procedure should be repeated again, if after all appliances are turned on (except for air
conditioning and defroster), and the check shows Alternator Good LED lights,
alternator is good.
NOTE: Do not turn on air conditioning, or the defroster system to load the alternator. These appliances NOTE:
may start operating in the middle of a measurement cycle and give an invalid results.
if the first check indicates the alternator is good, and the second or third repeat of the check indicates
the alternator is bad, there probably is some problem in the system. Problems can range from loose fan
belts to a diode going bad in the alternator. To begin the check press Alternator and to stop the check
press ON/OFF. Note that the FAULT light will light when the Alternator is bad; a good Alternator will
light the Alternator Good LED.
NOTE: NOTE: Do not charge the battery while waiting for the engine to warm. This will invalidate any
alternator check. The Digital Display should show the circulating pattern while the engine is warming.
