BATTERY TESTER
(MOTOROLA)
Connect the positive instrument clip
to battery positive (+) and negative
to negative (-). Set battery voltage
s w i t c h @ to 12V. t e m p e r a t u r e
compensator @ to the estimated
battery temperature, and current
calibrator @ to the battery amps
according to type.
Voltage test
1. Switch selector 0 t o V O L T .
2. The reading on the VOLT scale
must be greater than 12.4 V.

repeat the test. If the voltage again
shows less than 12.4V. a celle may
be shortcircuited. Change the battery
for another one.

Charge test
1. Set instrument selector switch to
VOLT.
2. Start the engine and let it idle
until the needle settles to its reading.
3. The reading

4. If the reading is outside (above
or below) these limits, check the
alternator for defects, especially the
voltage regulator (see Charging -
Checks and Inspections).
