Personal Precautions
Risk of explosive gases.
Never smoke or allow a spark or
ame in the vicinity of a battery.
Batteries can produce a highly explosive mix
of hydrogen gas and oxygen, even when the
battery is not in operation. Always work in a
well-ventilated area.
Wash hands after handling.
REQUIRED BY CALIFORNIA PROP. 65: Battery posts,
terminals, and related accessories contain lead and lead
compounds, chemicals known to the state of California to
cause cancer and birth defects or other reproductive harm.
Inspect the battery for damage and check the electrolyte level.
If the electrolyte level is too low, replenish it and fully charge
the battery. Always use the necessary safety precautions when
working with batteries to prevent severe injury or death.
Follow all manufacturers’instructions and BCI (Battery Council
International) safety recommendations, which include the
following precautions:
Battery acid is highly corrosive. If acid enters your eyes,
immediately ush them thoroughly with cold running
water for at least 15 minutes and seek medical attention.
If battery acid gets on your skin or clothing, wash imme-
diately with a mixture of water and baking soda.
Always wear proper safety glasses or face shield when
working with or around batteries.
Keep hair, hands, and clothing as well as the analyzer
cords and cables away from moving engine parts.
Remove any jewelry or watches before you start servicing
the battery.
Use caution when working with metallic tools to prevent
sparks or short circuits.
Never lean over a battery when testing, charging, or jump
starting.
Symbols Conventions
Symbol Description
!The safety symbol indicates instructions for
avoiding hazardous conditions and personal injury.
The safety symbol with the words CAUTION,
WARNING, or DANGER indicates instructions for
avoiding hazardous conditions and personal injury.
The wrench symbol indicates procedural notes and
helpful information.
Description
The analyzer uses function-specific applications accessed
through a series of menus and icons to guide users through the
battery testing process for consistent testing implementation
and accuracy. These are accessed using the tester’s touch
screen display. Test results can be displayed on the full-color
screen, printed, or wirelessly emailed.

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. Re-
pair 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 ½ 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.
Failure to properly install lead terminal adapters,
or using adapters that are dirty or worn, may
cause false test results.
When testing side-post or Group 31 batteries, always use lead
terminal adapters provided with the tester—do not test at
the battery’s steel bolts. To avoid damage, never use a wrench
to tighten the adapters more than ¼ turn.
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. Otherwise, you must remove the battery
and perform an out-of-vehicle test.
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.

1: IntroductionJDT-1
Connecting To A Battery
Do not connect the tester to a voltage source
greater than 30 Vdc.
Connect the clamps to the tester: the red clamp to the positive
(+) terminal and the black clamp to the negative (–) terminal.
If the clamps are connected with the wrong polarity (positive
to negative or negative to positive), the tester displays
CLAMPS REVERSED! Reconnect the clamps.
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.

of your analyzer by setting preferences in the Settings ( )

Appendix B:Test Results Decision TablesJDT-1
Starter Test Results
Decision Action
Cranking
Normal
The starter voltage is normal and the battery is fully charged.
Low Voltage
The starter voltage is low and the battery is fully charged.
Charge Battery
The starter voltage is low and the battery is discharged. Fully
charge the battery and repeat the starter system test.
Replace Battery
(If the battery test result was (REPLACE or BAD CELL.) The
battery must be replaced before testing the starter.
Low Current
The starter voltage is high but the cranking amps are low.
No Start
The engine didn’t start and the test was aborted or the
vehicle’s starting prole was not detected and the Starter
Test was skipped.
Alternator Test Results
Decision Action
CHARGING
NORMAL
The output from the alternator is normal.
NO OUTPUT
No output detected. Check belts to ensure alternator is
rotating when engine is running.
√Check all alternator connections including to the
battery. Clean or replace if necessary and retest.
√If the belts and connections are in good working
condition, replace alternator or external voltage
regulator.
LOW OUTPUT
Alternator not providing enough current to power electrical
loads and charge the battery.
√Check belts to ensure the alternator is rotating with the
engine running.
√Check alternator connections to and from the battery.
If loose or heavily corroded, clean or replace the cable
and retest.
HIGH OUTPUT
Alternator voltage to the battery exceeds normal limits of a
functioning regulator.
√Check for loose and normal ground connections. If no
connection problems are found, replace the regulator.
The normal high limit of a typical automotive regulator is 14.5
volts +/–0.5. Refer to the manufacturer specications for the
correct limit, which may vary by vehicle type.
Diode Test Results
Decision Action
EXCESSIVE
RIPPLE
One or more diodes in the alternator are not functioning or
there is 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
Replace the alternator.

Appendix C: Recommended Test Procedure JDT-1
The Conductance Proling™ technology determines battery
cranking and Reserve Capacity testing. This additional process,
can take up to 60 seconds to complete.
IMPORTANT: Always begin each test by connecting
the Tester Pod clamps to the battery being tested . The
test begins as soon as the clamps are connected.
VIN Scanning
The JDT-1 uses a camera built into the Controller handle to
scan the VIN of the vehicle being tested. This number is then
cross referenced with the original equipment manufacturer's
battery specications stored in the tester's database and
displayed on the Controller screen.
Scanning Tips
•Camera: Located in the upper left portion on the back of
the Controller handle.
Flashlight
Camera
•Hold Steady: Hold Controller steady when scanning the
VIN barcode. This allows the user to clearly see the bar-
code and allows the camera to focus on it.
Acquire VIN 93%
Flashlight
Fill the viewnder with the VIN and center it along the red line.
Or enter VIN using:
Back Manual Entry Yr/Make/Model
•Fill Viewnder: Make sure the entire barcode is visible.
Keeping the entire VIN barcode visible while slowly mov-
ing the camera closer or further away will help capture.
•Clean Barcode/Window: Surface dirt can interfere with
the scanning process. If necessary wipe the VIN barcode
with a cloth or your nger remove any surface dirt.
•Lighting/Glare: The built-in ashlight will automatically
turn on In low light situations. If the ashlight, or sunlight,
is shining directly onto the VIN barcode, try pivoting the
camera up or down slightly to reduce any glare.
