PART 2
Under Load (accessories ON): Next, load the alternator by turning on as many accessories as
possible (Front light, wiper blade, A/C, fan, etc.). This test under load allows you to check if the
alternator is able to supply enough current together to the battery and electrical accessories of your
car.
Refer to the operation as described above.
Notes: Press any buttons during alternator checking process, the unit will go to the
corresponding mode.
The unit may detect that the alternator is out of typical voltage range because someone has
added a number of accessory loads on the charging system, thereby increasing current
demand from the alternator.
MAKE SURE THAT THE ALTERNATOR IS RATED TO SUPPORT THE APPLICATION.
This check may not be accurate for every make, manufacturer and model of car.
Check only 12 volt systems.
