TESTING THE CHARGING SYSTEM - after load test
1. Connect the tester the same way for battery testing.
2. Start the engine and allow it to reach normal operating temperature.
3. Run engine at 1200 to 1500 RPM. CAUTION: Stay clear of moving engine parts.
4. Read the meter.
For H3650 DIGITAL BATTERY LOAD TESTER
A reading in the red LED light indicates a problem in the charging system that will un-
dercharge a battery (less than 13.6V), or overcharge the battery (over 14.8V) .Please
refer to volts meter.
For H3432 BATTERY LOAD TESTER
A reading in the red band area indicates a problem in the charging system that will un-
dercharge a battery; if the meter is beyond the OK area, the charging system is likely to
overcharge the battery.
STARTER MOTOR TEST (12VOLT VEHICLES)
This test identifies excessive starter current draw, which makes starting difficult and short-
ens battery life. Perform battery load test-proceed to make sure if battery is GOOD.
ENGINE MUST BE AT NORMAL OPERATING TEMPERATURE
1. Connect negative (black) clamp to the negative (NEG, N, -) battery post. Connect
positive (red) clamp to the positive (POS, P , +) battery post. ROCK clamps back and
forth to ensure a good electrical connection.
2. Disable the system ignition so the vehicle will not start.
3. Crank the engine and note the voltage reading during cranking.
4. A meter reading of 9 volts or less indicates excessive current draw. This may be due to
bad connections or a failing starter motor, or the battery is too small for the vehicle's
requirements.
