What to Expect from the BVA-200s:
Immediately recognize a bad battery and perform a complete
charging system analysis.The BVA-200s is a portable full-featured
menu-driven battery tester and charging system analyzer that provides
quick, professional load results using Auto Meter's Pulsed Differential
Load. Quick battery checks will increase charging productivity. The
BVA-200s is user friendly. It tells you what to do. The stator-diode test
automatically indicates open or shorted stator-diodes. It is professionally
accurate. Detailed test results are displayed after each test or can be
reviewed and/or printed from memory.
Caution: The BVA-200s grill may get hot after repeated use. Be sure to
hold the unit from the side grips only. Keep hands away from the grill.

Note: The BVA-200s checks and load tests 6 volt and 12 volt
Batteries and tests the starter and alternator on 12 volt and 24
volt systems. The following examples illustrated are for a 12 volt
system. The BVA-200s automatically identies the appropriate
voltage and displays the menu selection and instructions needed
for that system.

SAFETY
Carefully read all operating instructions before
using the BVA-200s
Wear eye protection when working around
batteries.
Be sure each test is completed before removing
load clamps to prevent arcing and potential
explosion from battery gases. Never remove load
clamps while testing. Keep sparks ames, or
cigarettes away from batteries.
Keep hair, hands, and clothing as well as tester
leads and cords away from moving blades and
belts.
Provide adequate ventilation to remove car
exhaust.
In extremely cold temperatures, check for frozen
electrolytic uid before applying load. Do not attempt to Load Test or charge a battery
under 20 degrees. Allow the battery to warm to room temperature before testing or
charging.
Warning! Never attach the BVA-200s to a battery that is connected to any other
tester or charging unit. Damage may result.
Incorrect Application: Wrong size battery may have inadequate cold
cranking rating for original vehicle specications.
Incorrect Installation: Loose battery hold-downs cause excessive vibration,
which can result in damage to the plates.
Improper Maintenance: Low electrolytic uid and corrosion on battery
connections can greatly reduce battery life and affect battery performance.
Age of Battery: If the date code on the battery indicates it is fairly old, the
failure may be caused by natural causes.
Overcharging: Overcharging caused by a high voltage regulator setting or
incorrect battery charging can cause excessive gasing, heat and water loss.
Undercharging: Undercharging caused by a faulty charging system or
low voltage regulation can cause lead sulfate to gradually build up and
crystallize on the plates greatly reducing the battery’s capacity and ability to
be recharged.

MAINTENANCE
Both jaws of each clamp
must rmly engage the
battery terminal. The
copper jaw contains the
smaller gauge wire that
reads the voltage and
the silver jaw contains
the larger conducting
wire that draws the
load in each test. Jaw
insulation is necessary
for accurate readings.
Damaged clamps or
loose wires will affect the
readings. Keep clamps
clean and in good repair.
CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL PLASTIC
SHOULDER INSULATORS
BATTERY CLAMP REPLACEMENT
Over time the battery clamps will need to be replaced if any of the
following are indicated:
CCA values seem to be way off.
If there is continuity between the silver and copper jaw.
If there is excessive damage or corrosion to the cables or
clamps.
PROCEDURE
Disconnect the back cover.
Disconnect the two small wires from the PCB.
Remove the large cables from the copper busses.
Carefully pull each wire through the grommets.
Reverse the procedure when installing new clamps.
Caution: With cables pointing down, make sure the red clamp
wires are attached to the left buss and the black clamp is attached
to the right buss. Putting a little mineral spirits on the new cable
ends will help with ease of insertion through the grommets.
BATTERY REPLACEMENT
When the LCD indicates a low internal battery remove the back cover
and replace the battery with a 9 volt Alkaline battery.

Press the On/Off button: Connect the clamps as instructed on the LCD.
Note! Take special care when connecting to battery side terminals. If
necessary use a side post adapter to prevent thread damage. When
testing dual post batteries always check the post to which the system is
attached. If a load test is made from a post connection and the alternator
is mounted to side terminals a battery load test can be completed, but
a continuity problem may still be in the side terminals when testing the
alternator.

3SYSTEM TEST OVERVIEW
Symptomatic Check before Proceeding:
Check all cables and connections.
Check the battery for corrosion and dirty terminals.
Check starter/solenoid for visual defects.
Check the ignition switch and any magnetic switches for loose or
bad wiring, loose mounting, or connections and sticking contacts.
Check for starter/solenoid noise. The type of noise or the lack
thereof can help in diagnosing the problem.
Does the solenoid click, but the starter does not turn? Does the
starter turn, but not engage the ywheel? Is the starter sluggish?
Note: A remote starter switch can be used to bypass the ignition switch and crank
the engine from under the hood. This way the sounds of the starter can be heard.
Press (N Esc.) to return to main menu. Select System Test then press (Y Enter).
Use the (+Up) and (-Down) to move
cursor to the desired test
SYSTEM TEST
The System Test will test the vehicle battery, starting system, and charging
systems in a quick logical order. Since a bad or discharged battery will greatly
affect the measurements done during the starting system and charging system
test, the BVA-200S will only allow those tests to be done after the battery has
been determined to be good and charged. The Starting Test measures the
amount of current needed to crank the engine and provides the initial information
to diagnose and/or further test the starting system if necessary.
Replace battery with a known
good, fully charged battery
and then rerun the system
test. Pressing 'Y' will return to
the main menu.
Charge the battery and
rerun the system test.
Pressing 'Y' will return to
the main menu.
A battery test as described in Section 2 will be performed rst. If the battery is found

If manufacturer's specications are not available the chart below can be used as
a general guideline. The amounts are in Amps.
There are a few points to consider in testing a starting system on a diesel engine.
The BVA-200S is designed to recognize any signicant amount of draw; this
includes glow plugs in small diesel engines. In heavy-duty applications consider
computer and accessory draw.
• Make sure you start the engine quickly. The engine should be warm.
• Turn the ignition on and allow the glow plugs to heat up and click off before you
run the Starting Test.
• Repeat the test in different ways and compare results.
If the results are out of specication do the following:
After the starting system test the following screen will be displayed.
• Inspect the connectors for excessive voltage drop.
• Repair or replace any defective cables or connectors.
• Retest the system.

SYSTEM TEST OVERVIEW cont.
This test measures the output of the charging systems under
load conditions. This information provides the basis for fur-
ther charging system tests. It also detects the presence of an
open or shorted diode that causes an output loss of several
amps and can cause the failure of other diodes.
Symptomatic Check before Proceeding:
Battery should be in good condition and charged before testing the
Charging System.
Check warning light indications.
Check belt condition and tension.
Check all cables and connections.
Check the battery for corrosion and dirty terminals.
Does the battery have a low state of charge? (See section 2 and 3)
Make sure all electrical items are off.
Check for Alternator noise.
Allow the charging test to nish.
Test result will appear. The following are examples.
Alternator has GOOD
regulation and GOOD
output.
High Regulation will damage the
system. High Regulation is likely due
to a faulty alternator and/or voltage
regulator.
