Charging System Test
Warning:
When testing a system in a car/truck, the vehicle must be on a flat, dry surface. The
transmission must be in park and the emergency brake engaged.
Do
not
push the Test Button (A) during this test.
1. Connect the Red Clamp (+) to the positive (+) terminal post on the battery.
2. Connect the Black Clamp (-) to the negative (-) terminal post on the battery.
3. Check the Battery Tester LED Window (See FIGURE) to determine effectiveness of charge.
4. If the Battery Tester does not register and no display is seen, double check that the clamps are
connected to the proper terminal posts.
5. Make certain a clean connection has been made between the clamps and terminal posts.
6. Start the engine and let it run.
7. Observe the voltage readout when the engine speed reaches between 1200 to 1500 RPM.
8. Determine the condition of the charging system on the basis of the table:
Charging system

< 13.5 V
13.5 – 14.4 V
>14.4 V

Starter System Test
1. For this check-up, the engine has to be in working temperature and the battery has to be in
perfect condition.
2. Connect the red clamp to the positive terminal and the black clamp with the negative terminal.
3. Start the Battery Condition Test (descripted above).
4. Monitor the measured voltage during the test.
5. If the voltage keeps decreasing after approx. 10 sec., this check-up is not available.
6. Take notes of the measured voltage, if it levels at a particular reading after approx. 10 sec.
Caution
: Do
not
operate the load switch (A) during the next step 7.
7. Start your vehicle (a second person is necessary) and compare the measured voltage during the
start with the measurement from step 6.
Example
•
If you read a stress test measurement of approx. 10.4V (step 6) and a measurement of 9.7 Volt
while starting your vehicle, there is no problem with your ignition system.
•
In case of a lower reading than 9.7 Volt, your Starter System is malfunctioning. Compare the data
from the following or the voltage table on the front of the battery tester.
