3.2.
BATTERY CHARGE LEVEL
WARNING! Ensure that vehicle, or battery, is in a well ventilated area before testing.
p
3.2.1. Confirm that all vehicle electrical systems are switched off and that the ignition is off.
If the engine has been running just before the test, turn on the side lights for approximately two minutes, then turn them off and wait
a further minute before testing.
3.2.2. Attach the small positive (red) clamp (fig.1.3) to the positive (+) battery terminal and the small negative (black) clamp (fig.1.3) to the
negative (-) terminal. Slightly twist clamps on terminals two or three times to ensure a good electrical contact and a firm grip.
3.2.3. Read battery voltage on display and compare with table (fig.2.C) to determine charge level.
3.3.
BATTERY LOAD TEST
NOTE: 1) ON THE FIRST LOAD TEST SMOKE MAY BE EMITTED FROM THE LOUVRES IN THE TESTER CASING. THIS IS OIL BURNING
OFF THE LOAD COILS AND IS NORMAL.
2) DO NOT LOAD TEST IF THE BATTERY VOLTAGE, AS DETERMINED IN 3.2., IS BELOW 12.35 VOLTS. RECHARGE BATTERY FIRST.
3) DO NOT LOAD TEST BATTERIES SMALLER THAN 32AH CAPACITY.
3.3.1. Connect the small clamps to the battery as in 3.2.2.
3.3.2. Connect the large clamp (fig.1.2) to the battery negative terminal and then firmly press the spring loaded probe (fig.1.1) onto the battery
positive terminal. DO NOT keep the probe on the terminal for more than 10 seconds (see timer, fig. 2.D) or the tester may overheat.
3.3.3. Note the voltage on the display at approximately 10 seconds, just before removing the probe from the battery terminal. 9 volts or higher
indicates that the battery is in good condition.
3.3.4. a) If the reading is between 8 and 9 volts, charge the battery for 5 minutes at 30 amps and then retest.
b) If the displayed voltage falls quickly at the start of the test or the display closes down then either the battery is faulty or is extremely discharged.
Charge for 12 hours at a current equal to one tenth of the battery capacity figure (ie if capacity is 45Ah then charge at 4.5 amps)
and then retest.
Note:
The red ‘Stop’ LED (fig.2.A) will come on if the tester overheats, typically after 3 or 4 consecutive load tests. When this happens
terminate test and wait for the tester to cool down.
3.4.
ALTERNATOR TEST
3.4.1. Connect the small clamps to the battery terminals, as in 3.2.2.
3.4.2. Start the engine and allow it to reach normal operating temperature. Switch off all accessories.
3.4.3. Run engine at 2000rpm and note the display reading, which should be between the values shown on panel C (fig.2).
3.4.4. A low reading indicates a fault which will cause the battery to be under charged. LIkely causes are faulty rectifier, high resistance in
cable to battery or slipping drive belt.
A high reading indicates a fault which will cause the battery to be over-charged. Likely cause is a faulty voltage regulator.
3.5.
EQUIPMENT SUPPLY CHECKS
3.5.1. Connect the small black clamp to the battery negative terminal and the red clamp to the positive connector on the equipment in question.
3.5.2. Switch on the equipment and note the display. A voltage of 11.5 or higher indicates that the supply circuit is OK. A lower voltage indicates
high resistance and no voltage indicates open circuit.
