Description
Introduction
This tester is designed to test 12V automotive lead-acid storage batteries and
12V automotive starting/charging systems. It uses advanced conductance
testing technology and can easily, quickly and accurately test the actual cold
cranking amps capability of automotive battery, health state of automotive
battery, automotive cranking system and charging system. It can be used by
maintenance personnel to troubleshoot automotive battery problem and
automotive starting/charging system problem.
Main functions of this tester include 12V automotive battery test, 12V
automotive cranking system test, and 12V automotive charging system test
functions.
Features:
1. Tests all 12V automotive cranking lead acid batteries, including ordinary
lead acid batteries, AGM flat plate batteries, AGM spiral batteries, Gel
batteries, and etc.
2. Directly detects bad cell battery.
3. Reverse polarity connection protection. Reverse polarity connection will not
damage the tester or affect the vehicle and battery under test.
4. Directly tests low battery, no need to fully charge battery before test.
5. Test standards include most battery standards around the world: CCA, BCI,
CA, MCA, JIS, DIN, IEC, EN, SAE, GB.
6. Selectable languages. Chinese, English, Japanese, Russian.

1.Charging Voltage: Normal
The charging system shows that the alternator output is normal, no
problem detected.
2. Charging Voltage: Low
Charging voltage of the charging system is low.
Please check whether the driving belt of the alternator is loose or
broken, and check whether the connections between the alternator and
the vehicle battery are good.
If the belt and the connections between the alternator and the vehicle
battery are good, the alternator is likely faulty.
3. Charging Voltage: high
Alternator voltage output exceeds the normal limits.
Most alternators use a built-in regulator, and for this kind of alternators,
it is necessary to replace the alternator assembly to solve the problem
of abnormally high charging voltage. Some conventional alternators use
an external regulator, and for them, just replace the regulator.
Usually, the charging voltage is limited to 14.7 ± 0.5V by the regulator.
If the charging voltage is too high, the battery will be overcharged and
as a result the battery life will be shortened or the battery will be
damaged.

4. No Voltage Output
No alternator output voltage is detected. Please check whether the
alternator's connections are good and whether the driving belt of the
alternator is tight enough.
5. Diode Test
Through the test of charging current ripple, you can determine whether
the rectifier diodes are good. If the ripple voltage is too high, it means
that one or more rectifier diodes are damaged or the alternator stator is
damaged. Please check for the bad diode(s) and replace all bad diodes,
and check the alternator stator.
