Cranking test
Select “2 starting system test” then press OK:
Start engine when prompted; SPTG1 will automatically complete the cranking
test and display the results.
Normally, cranking voltage value lower than 9.6V is regarded as abnormal, but
it is OK if it is higher than 9.6V. The test result of the SPTG1 will include actual
cranking voltage and actual cranking time.
When cranking test is abnormal, battery test result will also be displayed at the
same time.
This is for the convenience of the technician to quickly know the current state
of the starting system before proceeding.
Charging system test
When entering the “3 charging system test”, SPTG1 will prompt “Loaded
testing”
Note: Do not shut down the engine during the test. All non-essential items
should be turned OFF. If left ON, the test will be affected and could compro-
mise the accuracy of test results.
Adjust throttle/accelerator to increase the engine speed to 2500 RPM, and
hold for 5 seconds.
SPTG1 starts the charging volt test after the increase in RPM is detected.
After the test is finished, the SPTG1 will display the charging voltage, ripple
test, and charging test results.
