Associated Equipment 6033 WARNING:

2. Connect positive (red) clamp to positive (POS, P, +) batt ery pos t . Conn ec t negat i ve

(black) clamp to the negative (NEG, N,-) battery post. "Rock" clamps back and forth to

insure a good electrical connection. For batteries wi th side terminals, use the side

terminal adapters in the clamps.

3. As soon as the tester is connected to the batter y, the tester will take a reading of

the battery Open Circuit Voltage (OCV) before any load is placed on the battery. The

tester display will flash then show the battery voltage (Vb) at that moment. W hile the

voltage is displayed, the tester will be recording t he Maximum voltage (Vmax) and

Minimum voltage (Vmin) measured. Batteries load tested in a dischar ged state (Vb <

12.2 volts), may result in an inaccurate CCA. Attempt to rechar ge these batteries and

then retest.

NOTE: The 6033 tester uses the battery under test for power. If the batt ery volt age is

less than 7.5 volts, the display will not come on. If when connecting the tes t er ,

the display does not light up, check for correct polar ity hookup. If correct,

charge the battery and try again.

4. Press and hold the load switch to place a load on the batter y. The t ester m onitors

the voltage, after determining the load is no longer needed (5 to 10 sec onds ) t he dis pl ay

will flash, indicating to release the load switch. The tester wil l calculate the battery

capacity and begin to cycle through the sequence of four displays (Vb, Vmax, Vmin and

CCA).

5. If the battery state of charge is too low to calculate the CCA or t he battery is to

small (<100CCA) then the test will display “LO” for the CCA.

6. If the load switch is not pressed within 10 seconds after tes ter connection to

battery, the tester will begin to cycle through the display sho wing the Vb, Vmax and

Vmin. The LED’s under the display indicate which value is being displayed.

WARNING: THE TOP AND REAR OF TESTER WILL HEAT UP DUE TO LOAD

CURRENT. WITH 12-VOLT BATTERIES ALLOW TESTER TO COOL ONE

MINUTE BETWEEN LOAD TESTS - MAXIMUM OF 3 LOAD TESTS IN 15

MINUTE PERIOD. EXCEEDING DUTY CYCLE MAY CAUSE INCORRECT

READING AND DAMAGE TO THE UNIT.

TEMPERATURE COMPENSATION FOR BATTERY LOAD TEST

Low temperature has a degrading effect on batteries and will affect test res ults. The

CCA reading will drop approximately 1% for each 2°F the battery t emperature is bel ow

80°F. for instance a battery at 40°F will read 80% of the actual CCA value. An

example: on a battery at 40°F the tester shows the battery CCA value at 400 so the

actual value is 400/.80 = 500CCA.

CHARGING SYSTEM TEST

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

overcharging - which leads to poor battery performance and short l ife.

ENGINE SHOULD BE AT NORMAL OPERATING TEMPERATURE

1. Turn off all lights and accessories. Operate engine at f as t i dle ( a ppr oximat el y 1 500

RPM).

2. Connect tester clamps to battery as described in Step 2 under Batter y Load Test.

NOTE: If the tester is still connected to the battery from a previous test, it is

necessary to disconnect one of the clamps to reset the tester bef ore

performing another test.

3. Do not press the tester’s load switch, turn on the lights, tur n on the high beams,

and put the blower on high, after about 3 sec turn off the lights and blower. C heck

the tester display will show Vb, Vm ax and Vmin. The user can then verify t hat

these readings are within the recommended values of t h e vehi c le m anuf ac tur er (f or

instance normal voltages would be in the range of 13.5 to 1 4.4V). Voltage readings

out of the range would indicate a bad alternator, regul ator or circuit issue ( belts,

cable connections).

4. For larger alternators the tester load may also be used for l oading the batt ery and

alternator. Compare the tester readings with the v ehic l e’s r ec ommend ed valu es as

in step 3.

If the tester display starts to flash (like under battery load test) leave the loa ds

(lights and blower) on and disconnect and reconnect t he tester and then turn off the

loads.

STARTER MOTOR TEST

This test identifies excessive starter current dr aw, which makes starting diffic ult and

shortens battery life.

ENGINE MUST BE AT NORMAL OPERATING TEMPERATURE

1. Perform Battery Load Test. Proceed if battery is good.

2. Disconnect one tester clamp to reset tester’s circuit board.

3. Reconnect the tester clamp.

4. Start engine with tester connected to the battery.

Note: If engine does not start in 5 seconds, release start switch.

5. The (Vmin) reading will be and indication of how good the starter is. (For instance

a voltage below 7.2V indicates excessive current draw. This may be du e to bad

connections or a failing starter motor, or the battery m ay be too small for the

vehicle’s requirements.

If the voltage to the tester drops below 6V the unit will reset. This can be evi dent if

no voltage drop is seen. For example after the vehicle is started the Vmin reading

is similar to Vb.
