Associated Equipment 6026 - Manual (Page 2)

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 50
°, read scale 100 CCA less then battery rating.
If battery is 30 °, read scale 200 CCA less than battery rating.
If battery is 10 °, read scale 300 CCA less than battery rating.
LOAD TEST ANALYSIS
METER ACTION AT END OF 10 SECONDS
BATTERY CONDITION INDICATED
NEEDLE IN TEMPERATURE CORRECTED
GREEN SCALE.
BATTERY IS GOOD.
LITTLE IF ANY MOVEMENT, NEEDLE IN
TEMPERATURE CORRECTED YELLOW
SCALE.
BATTERY QUESTIONABLE, RECHARGE
AND RETEST.
NOTICEABLE METER MOVEMENT
AND/OR NEEDLE IN TEMPERATURE
CORRECTED RED SCALE.
BATTERY IS DEFECTIVE.
NOTE: TOP AND REAR OF TESTER WILL HEAT UP DUE TO LOAD
CURRENT. ALLOW TESTER TO COOL ONE MINUTE BETWEEN
LOAD TESTS - 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
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.
