BATTERY LOAD TEST

This test evaluates the battery's ability to crank an engine. The tester draws current

from the battery while measuring its voltage level. The voltage level of a good battery

will remain relatively steady under load, but a defective battery will show a rapid loss in

voltage. Battery size (CCA rating) and temperature will affect test results - follow

instructions carefully.

1. Turn off engine, accessories and battery test equipment.

2. Connect negative (black) clamp to the negative (NEG, N,-) battery post. Connect

positive (red) clamp to positive (POS, P, +) battery post. "Rock" clamps back and

forth to insure a good electrical connection. For batteries with side terminals, use

the adapters in clamps.

3. With clamps connected, tester's meter will indicate battery's STATE OF CHARGE. If

state of charge is less then 12.4 (6.2) volts ("–" symbol on meter), the battery

should be recharged before load testing. If recharging does not bring voltage to

12.4 (6.2), battery is defective. If meter needle is off scale to the left, check for loose

or reversed clamps; otherwise battery is defective.

4. Note battery's rating in Cold Cranking Amps (CCA). If the rating is not printed on

the battery, use the following guidelines to estimate battery size. Small (4 cyl) -300

CCA; Medium (6 cyl) -400 CCA; Large (8 cyl) -500 CCA.

5. Depress load switch for 10 seconds.

6. Read meter at the end of 10 seconds - with switch depressed. Refer to LOAD

TEST ANALYSIS chart.

COMPENSATING FOR LOW TEMPERATURES

Low temperature has a degrading effect on batteries and will affect test results.

This can be compensated by reading a different scale.

If battery is 50E, read scale 100 CCA less then battery rating.

If battery is 30E, read scale 200 CCA less than battery rating.

If battery is 10E, read scale 300 CCA less than battery rating.

MAXIMUM OF 3 LOAD TESTS IN 5 MINUTE PERIOD. EXCEEDING DUTY

CYCLE MAY CAUSE INCORRECT READING AND DAMAGE THE UNIT.

CHARGING VOLTAGE TEST (12 VOLT ONLY)

This test measures the output voltage of the alternator/regulator. Check for under or

overcharging - which leads to poor battery performance and short life.

ENGINE SHOULD BE AT NORMAL OPERATING TEMPERATURE

1. Connect tester clamps to battery as described in Steps 1-2 under Battery Load

Test.

2. Turn off all lights and accessories. Operate engine at fast idle (approximately 1500

RPM).

3. Do not operate tester's load switch.

4. Read meter voltage. Meter needle should be in Green (OK) area of Charging

System scale.

5. Turn on high beam lights and blower on high. Meter needle should remain in

Green (OK) area.

6. If meter needle goes to the Red (LO or HI) areas, the charging system is not

operating correctly.

Trouble Shooting Hints

LO Voltage - may be caused by loose belt, defective voltage regulator or defective

alternator.

HI Voltage - may be caused by loose or corroded connections or defective voltage

regulator.

STARTER MOTOR TEST (12 VOLT VEHICLES)

This test identifies excessive starter current draw, which makes starting difficult and

shortens battery life. Perform Battery Load Test - proceed if battery is "Good".

ENGINE MUST BE AT NORMAL OPERATING TEMPERATURE

1. Connect tester clamps to battery as described in Steps 1-2 under Battery Load

Test.

2. Disable the ignition so the car 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.

BATTERY FACTS

1. A fully charged battery at 0°F has only 40% of the cranking power it has at 80°F.

2. Battery failure is frequently caused by overcharging.
