Chapter 3: Test Preparation
Inspecting the Battery
Before starting the test visually inspect the battery for:
•Cracked, buckled, or leaking case. If you see any of these
defects, replace the battery.
•Corroded, loose, or damaged cables and connections.
Repair or replace them as needed.
•Corrosion on the battery terminals, and dirt or acid on
the case top. Clean the case and terminals using a wire
brush and a mixture of water and baking soda.
•Low electrolyte level. If the electrolyte level is too low,
add distilled water to ll up to 1/2 above the top of the
plates and fully charge the battery. Do not overll.
•Corroded or loose battery tray and hold-down xture.
Tighten or replace as needed.
Testing Out-of-Vehicle
The preferred battery test location is in the vehicle. However,
if you plan to test out of the vehicle:
•Always disconnect the negative cable from the battery
rst and reconnect it last.
•Always use a carry tool or strap to lift and transport the
battery.
Testing In-Vehicle
The preferred test position is at the battery posts. If you must
test at a remote-post location, it should have both a positive
and negative post.
At the start of the test, make sure all vehicle accessory loads
are o, the key is not in the ignition, and the doors are closed.
Connecting the Battery Test Cable
CAUTION: Do not connect the tester to a voltage source
greater than 30 Vdc.
Connect the battery test cable to the tester by rst aligning
the cable connector’s 6 pins with the holes on top of the
tester. Firmly insert the connector and tighten the locking
ring.
Connect the clamps to the battery: the red clamp to the
positive (+) terminal and the black clamp to the negative (–)
terminal.
If you connect the clamps in the wrong polarity (positive to
negative or negative to positive), the tester displays CLAMPS
REVERSED! Reconnect the clamps correctly.
To make sure both sides of the clamps are gripping the
terminals, rock the each clamp back and forth. A poor
connection will prevent testing, and the tester will display
the message CHECK CONNECTION. If the message reappears
after you have correctly reconnected the clamps, clean the
terminals and reconnect.
Connecting an Accessory Cable
If you are using an accessory cable, plug it as you would a
phone jack into the accessories port on top of the tester. It
locks automatically into the port. To remove it after testing,
press the lever and pull the connector out.
Setting User Preferences
Before starting your test you may want to customize the use
of your analyzer by setting preferences in the Utility Menu.
The menu has settings for the display’s date and time, the
contrast and backlight time, a utility to customize printouts
for the optional IR printer, among others.
To conserve the analyzer’s internal batteries, the tester will
turn o after 30 seconds of inactivity.

Chapter 4: Battery Test
Additional Test Requirements
For a more decisive result the tester may ask for additional
information or probe deeper into the battery’s condition. The
following messages and instructions may appear before the
analyzer displays the results of your test.
System Noise
To perform a correct measurement the tester requires the
vehicle to be in rest. After the car has been driven some vehicle
specic systems might still be active in the background.
The tester will detect this and displays the message
SYSTEM NOISE. When this message appears switch o all
consumers(radio, airconditioning) and remove the key from
the ignition. As soon as there is no more activity in the vehicle
the tester will continue testing and display the test result.
Unstable Battery Detected
A battery that is weak or that has just been charged may retain
enough electrical activity to be detected by the analyzer
and will adversely aect the test results. A fully charged
battery should stabilize quickly, after which the analyzer
will automatically retest. Weak batteries should be charged
and retested. If the battery is fully charged, check the clamp
connections.
Surface Charge
The battery can hold a surface charge if the engine has been
running or after the battery has been charged. The tester may
prompt you to remove the surface charge before it displays a
test result.
1. Follow the instructions indicating when to turn the head-
lights on and o (IN-VEHICLE)
2. The tester will resume testing after it detects that the sur-
face charge is removed.
Deep Scan Test
In some cases the tester may need to further analyze the
battery to determine whether the battery should be replaced
or it has a signicant chance to be recovered. It will then
conduct a Deep Scan Test of the battery for a few seconds.
This test will typically be performed on batteries that are in a
low state of charge.

Chapter 5: System Test
Before starting the test, inspect the alternator drive belt.
A belt that is glazed or worn, or lacks the proper tension, will
prevent the engine from achieving the rpm levels needed
for the test.
The System Test includes 3 tests that provide a complete
diagnosis of the vehicle’s electrical system:
•BATTERY TEST
•STARTER TEST
•ALTERNATOR TEST

Chapter 5: System Test
Alternator Test
1. The tester starts checking for alternator output.
NOTE: If necessary the analyzer will ask if you are
testing a diesel engine. It will resume testing after
you make your selection.
2. Depending on whether you are working with an inte-
grated Amp clamp, you will be either prompted to TURN
OFF LOADS AND ENGINE or asked to CHECK IF CLAMP
POINTS AWAY FROM THE NEGATIVE BATTERY POST.
In case of the former, turn o vehicle loads (blowers,
interior light, radio, etc.) and the engine. Press the NEXT
soft key to continue.
3. ANALYZING CHARGING SYSTEM DATA
4. TURN OFF LOADS AND ENGINE: Turn o vehicle loads
(blowers, interior light, radio, etc.) and idle the engine.
Press the NEXT soft key to continue.
NOTE: If necessary the analyzer will ask if you are testing
a diesel engine. It will resume testing after you make
your selection.
5. REV ENGINE WITH LOADS OFF FOR 5 SECONDS: Rev the
engine with the loads o. Gradually increase the rpm un-
til the analyzer tells you to HOL D the rev level as the bar
on the display crosses the rpm target line.
6. ACQUIRING DATA....HOLD ENGINE RPM: Continue to hold
the rpm while the Tester takes system measurements.
7. ENGINE REV DETECTED, IDLE ENGINE: The Tester has de-
tected the rev. Press the NEXT soft key to continue.
8. TESTING ALTERNATOR AT IDLE, LOADS OFF: The analyzer
will next test the engine at idle for comparison to other
readings, and then test the diode ripple. Excessive ripple
usually means one or more diodes have failed in the al-
ternator or there is stator damage.
9. TURN HIGH BEAMS AND BLOWER MOTOR ON, IDLE EN-
GINE: After a few seconds, the Tester will ask you to turn
on the accessory loads. It will determine if the charging
system is able to provide enough current for the de-
mands of the electrical system.
IMPORTANT: Turn on the high-beam headlights, the
blower to high and the rear defogger. Don’t use cyclical
loads such as air conditioning or windshield wipers.
10. TESTING ALTERNATOR AT IDLE, LOADS ON: The analyzer
will determine if the charging system is able to provide
sucient current for the demands of the vehicle’s elec-
trical system.
11. REV ENGINE WITH LOADS ON FOR 5 SECONDS: The Tes-
ter will test the charging system with the loads on and
prompt you to rev the engine. Gradually increase the rev
until the analyzer tells you to HOLD the rev level as the
bar on the display crosses the rpm target line.
12. ACQUIRING DATA....HOLD ENGINE RPM: Continue to hold
the rpm while the Tester takes system measurements.
13. ENGINE REV DETECTED, IDLE ENGINE: The Tester has de-
tected the rev. Press the NEXT soft key to continue.
14. ANALYZING CHARGING SYSTEM DATA: The Tester is com-
pleting its nal analysis of the charging system data.

Chapter 5: System Test
Alternator Decisions and Recommendations
Decision Action
NO PROBLEMS The system is showing normal output from the alternator. No problem detected.
NO OUTPUT The alternator is not providing charging current to the battery.
• Check the belts to ensure the alternator is rotating with the engine running. Replace
broken or slipping belts and retest.
• Check all connections to and from the alternator, especially the connection to the battery.
If the connection is loose or heavily corroded, clean or replace the cable and retest.
• If the belts and connections are in good working condition, replace the alternator. (Older
vehicles use external voltage regulators, which may require only replacement of the
voltage regulator.)
LOW OUTPUT The alternator is not providing enough current to power the system’s electrical loads and
charge the battery.
• Check the belts to ensure the alternator is rotating with the engine running. Replace
broken or slipping belts and retest.
• Check the connections from the alternator to the battery. If the connection is loose or
heavily corroded, clean or replace the cable and retest.
HIGH OUTPUT The voltage output from the alternator to the battery exceeds the normal limits of a
functioning regulator.
• Check to ensure there are no loose connections and that the ground connection is
normal. If there are no connection problems, replace the regulator. (Most alternators
have a built-in regulator requiring you to replace the alternator. In older vehicles that use
external voltage regulators, you may need to replace only the voltage regulator.)
Diode Decisions and Recommendations
Decision Action
EXCESSIVE RIPPLE One or more diodes in the alternator aren’t functioning or there’s stator damage, which is
shown by an excessive amount of AC ripple current supplied to the battery.
• Make sure the alternator mounting is sturdy and that the belts are in good shape and
functioning properly. If the mounting and belts are good, replace the alternator.
OPEN PHASE The Tester has detected an open phase within the alternator. Replace the alternator.
OPEN DIODE The Tester has detected a open diode within the alternator. Replace the alternator.
SHORTED DIODE The Tester has detected an shorted diode within the alternator. Replace the alternator.
