VOLTAGE DROP TESTS
The specications for those tests are listed below.
The minimum system voltage to run a test is 12.25 Volts for a 12 Volt
system and 24.5 Volts for a 24 Volt system.
During each battery test the BVA-2100/RYD uses various results that are
displayed after each test. The denition of those results are as follows:
• % Charge = an approximate amount of charge the battery is
currently holding. This is based upon the batteries voltage.
• Est. CCA = is the approximate CCA of the fully charged battery.
• GOOD BATTERY = a battery that is good and is charged.
• GOOD NEEDS CHARGE = a battery that is good but is low on
charge.
• MARGINAL BATTERY = a battery that has passed the load
test but the estimated CCA is getting low or the battery is
approaching its end of life.
• CHARGE and RETEST = a battery with insufcient charge to
provide accurate test results.
• BAD BATTERY = a battery that is bad and should be replaced.
A bad battery is a battery that failed the load test or had an
estimated CCA below about 70% of the rated value.
BATTERY TEST

1SYSTEM TEST INTRODUCTION
The system test is part of the Heavy Duty menu selection and not the
regular menu.
IMPORTANT NOTE: The difference between a system test and the
individual component test that follows in the menu is that each system
test, whether it be the battery bank, the charging system or the starting
system prompts you through each prerequisite test including the cables
and battery before the individual component is tested. The purpose is to
avoid component replacement when the problem may be in the cables
of the component being tested. The system test also allows error results
that prompt specic action. This manual includes detailed menu prompts
and instructions for the system test, but when it comes to the individual
component test of a battery, alternator, starter, cables or magnetic switch
you will be instructed to a certain segment of the system test to avoid
needless repetition in the manual.
As mentioned in the conguration section above there is no appearance
in this manual requesting the vehicle ID, technician ID etc. There are also
no prompts to inspect components of the system. See the conguration
section above for a better understanding if these items are required in
your training.
It is advisable to use only the system test until you become procient and
have good reason to test an individual component.
From the main menu select
SYSTEM TEST.
When System Test is selected,
the last test selection will appear.
You have a choice of BATTERY,
CHARGING or STARTING. If another
test appears in the LCD such as the
STARTING and you want BATTERY,
simply use the (+) or (-) key to select
BATTERY and then press (‘Y’ Enter).
NOTE: When selecting CHARGING or STARTER the system test will
automatically run the battery test rst to make sure the battery bank
passes. Therefore, you need only use the battery bank test for testing the
battery bank specically.

4CHARGING SYSTEM TEST
The System Test Introduction also applies to the Charging System Test.
See page 7. It is advisable to use only the system test until you become
procient and have good reason to test an individual component.
From the main menu and with the >
to the left Press ('Y' Enter) to select
System Test.
Simply use the (+) or (-) key to
select CHARGING and then press
('Y' Enter).
NOTE: When selecting CHARGING or STARTING the system test will
automatically run the battery bank test rst to make sure the battery bank
passes. See Battery Bank Test (page 10) for instructions. This section
covers the CHARGING SYSTEM section after the Battery System Test
is completed. You will be asked if the vehicle has a J1708 data port.
See page 33 for more information. This manual will assume no in all
examples that follow.
Enter rated alternator output.
Simply use the (+) or (-) key to
change the rating in units of 5
Amps. Press ('Y' Enter).
Connect large leads to the
Alternator then press ('Y' Enter) to
continue.
NOTE: just as it is important to determine the condition of the battery
system before testing the alternator it is also importanbt to test the cable
system, otherwise the alternator may be prematurely suspected when
it is either the battery system or the cable system. For this reason, the
following (beginning on page 15) represents the individual voltage drop
test required before the alternator test is completed.

Select LIFTGATE CHARGE,
LIFTGATE MOTOR or LIFTGATE
TRUCK CIR. to perform a voltage
drop test on the trailer charge
circuit, trailer liftgate motor
circuit or the truck’s liftgate
power circuit respectively.
The liftgate charging circuit includes the positive cables from the front of the
trailer to the liftgate batteries and the negative cables and/or frame from the front
of the trailer to the liftgate batteries.
The liftgate motor circuit includes the positive cables and the solenoid from the
liftgate batteries to the liftgate motor and the negative cables and/or from the
liftgate batteries to the liftgate motor.
The liftgate truck circuit includes the positive cables and the negative cables and/or
frame from the trucks batteries to the font of the trailer (end of the “stinger” cord).
Adapters are available from Auto Meter to facilitate connecting the BVA-2100 to
single pole and dual pole connectors on both trucks and trailers. See the manual
supplement that is included with those adapters for more detailed information on
testing and trouble shooting the liftgate charging circuits and liftgate motor circuits.
If the overall voltage drop is not within the desired specications the small leads
can be moved closer along the line being tested and the test run again (see
dotted lead on previous page). If the results are desirable, it is the section not
included in the last test. If the results are not desirable the problem is most likely
in the section being tested. Repair and test the entire section again.

Amp Probe is not around any cables
when zeroing. Instead of +00003 A, it
should read +00000 A.
You will then be asked to attach the
probe to a particular wire such as
alternator output or starter cable.
In the multimeters test the bottom
two lines will not appear if the Amp
Probe is not connected. In other test
results there may be slightly different
displays.
Direction of Current
In the Alternator test you will have two additional menu options if the
AMP Probe is attached on the rear of the tester. If the menus do not
appear the Amp Probe is not attached properly.
The following are examples of use within a test sequence.
