Testing
This test is to determine the electrical condition of the
battery and to give an indication of the remaining useful
`life'.
Before testing ensure that the battery is at least 75%
charged (SG of 1.23 to 1.25 for ambient temperature up to
27°C).
Ensure that the battery is completely disconnected from
the vehicle.
Connect up the battery tester as follows:
1 Set the CHECK/LOAD switch 7-A to OFF.
2 Set rocker switch 7-B to the battery voltage (12V).
3 Connect the red flying lead to the battery positive (+)
terminal and the black flying lead to the battery
negative (-) terminal.
4 Set the CHECK/LOAD switch 7-A to CHECK to read
the battery no-load voltage which should be at least
12.4 volts.
5 Set the CHECK/LOAD switch 7-A to LOAD and hold
down for 5-10 seconds until the meter reading
stabilises. The reading should be at least 9 volts.
Note: Do not hold the switch in the LOAD position for more
than 10 seconds.

Battery Tester Readings Remedy
1 CHECK: 0 - 12.6 Volts
LOAD: less than 6 Volts
Renew battery
2 CHECK: 6 - 12.4 Volts
LOAD: less than 9 Volts and falls steadily but remains
in yellow zone.
Recharge and re-test. If tests still unsatisfactory renew
battery.
3 CHECK: less than 10 Volts
LOAD: less than 3 Volts
Indicates battery has been over-discharged and unlikely to
recover. Renew battery.
4 CHECK: more than 11 Volts
LOAD: 6 - 10 Volts steady
Charge battery which will probably recover.
