LEAGEND Battery Tester BA101 User Manual
10
BA101
Operate accordingly to increase the engine rotating speed to 2500turns or above, and keep for 5 seconds.
Tester starts the charging volt test after increase rev detected.
After the test finished, tester displays the effective charging volts, ripple test result and charging test result.
NOTE: If no increase rev detected, it shall be the fault of generator regulator or connection with battery failed. Tester will try 3 times to further
detect, if still failed, it will skip the increase rev detect and the test result displays "No Volt Output". See below:
Check the connection between generator and battery, then retest.
Charging Test Result:
1) Charging Volt: Normal
Charging system shows the generator output normal, no problem detected.
2) Charging Volt: Low
Charging volt of the charging system is low.
Check drive belt of the generator whether slip or running off. Check the connection between generator and battery is normal or not.
If both of the drive belt and the connection are in good condition, follow the manufacturer's suggestion to eliminate generator fault.
3) Charging Volt: High
Generator output volt is high.
Since most of the vehicle generators are using internal regulator, the generator assembly has to be replaced.(Some old style cars are using
external regulator, then directly replace the regulator.)
The normal high volt of the voltage regulator is maximum 14.7±0.5V.If charging volt is too high, it will overcharge the battery. Therefore the
battery life will be shortened and troubles will be caused.
4) No Volt Output:
No generator volt output is detected. Check the generator connection cable and the belt whether they are normal.
5) Diode Test:
Through the test of charging current ripple, tester will find out whether the diode is normal or not. When ripple volt is too high, it proves at
least one diode is damaged. Check and replace the diode.
Till now, all tests have been done.
3.3 Battery out of vehicle test
OUT-OF-VEHICLE means battery is not connected with any of the vehicle loaded, i.e. battery connection is cut off.
Choose the battery out of vehicle test
Increasing RPM to 2500 r/min
And keep it 5 seconds.
Press OK to continue.
