Battery System Tester Operating manual AUTODITEX
“TEST ERROR” - The tested battery is bigger than 2000CCA or the clamps are not connected
properly. Please fully charge the battery and retest after excluding both the above
mentioned reasons. If the reading is the same, the battery should be replaced immediately!
- Press the “ENTER” (MENU) button to return to step 4 to continue testing or remove the
test clamps from the battery terminal after completion of testing batteries, to end the
test.
4. System test mode
This mode includes 3 sub tests:
- cranking voltage test;
- charging test with no loads – measures the alternator voltage with no loads when the
engine is idling;
- charging test with loads - measures the alternator voltage with loads when the engine
is idling;
Important: All 3 subtests of the system test are executed sequentially and there is no
possibility of changing their order!
4.1. Cranking voltage test
- When you connect the tester to a vehicle battery, the tester is in the default “BATTERY
TEST” mode. Press the “
►
“ button once to enter the “SYSTEM TEST” mode. The voltage
in format “XX.XX V” will also appear on the screen. Press the “Enter” (MENU) button to
go to the next step.
- The screen will show “TURN OFF LOADS START ENGINE”. Turn off all vehicle accessory loads
such as lights, air conditioning, radio, etc. and then start the engine. Wait for the tester
to detect the cranking voltage.
- When the engine is started and the test is complete, one of these three results will be
displayed along with the actual reading measured.
“CRANKING VOLTS NORMAL” - The system cranking voltage is in a good range.
“CRANKING VOLTS LOW” - The cranking voltage is below the normal limits. Troubleshoot the
starter motor with manufacturers recommended procedure.
“CRANKING VOLTS NO DETECTED” - The cranking voltage is not detected. Press the “Enter”
(MENU) button to go to the next step.
4.2. Charging test with no loads
- The screen will show “PRESS ENTER FOR CHARGING TEST”. Press the “Enter” (MENU)
button to begin system charging test.
- The screen will show “MAKE SURE ALL LOADS ARE OFF”. In this test the alternator idle
voltage will be measured. Press the “Enter” (MENU) button to go to the next step.
- The screen will show one of three possible results along with the actual reading measured.
“ALT. IDLE VOLTS NORMAL” - The system is showing normal output from the alternator. No
problem is detected.
“ALT. IDLE VOLTS LOW” - The alternator is not providing sufficient current to the battery.
Check the belts to ensure the alternator is rotating. If the belts are slipping or broken,
replace the belts and retest. Check the connections from the alternator to the battery. If the
