BATTERY REPLACEMENT
When the LCD indicates a low internal battery, the BVA-230OZR will shut
down and not operate until the 9 volt battery is replaced. Remove rubber
insulator boot, then remove the back cover and replace the battery.
ALTERNATOR TEST
This test measures the output of the charging systems under load
conditions. This information provides the basis for further 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?
Make sure all electrical items are off.
Check for Alternator noise.
Allow the alternator test to finish.
Test result will appear. The following are examples.
Alternator has GOOD
regulation and GOOD
output.
Bar at the bottom of the screen will
show the tests progress.
The BVA-230OZR will allow the
voltage to stabilize before starting
the test bar at the bottom of the
screen that shows the test progress.
Be patient, it can take up to 30
seconds for the voltage to stabilize.
Some vehicles have a fuel saving
feature that shuts down the alternator.
If the tester detects a low charging
voltage it will prompt you to turn on
the headlights and wait up to two
minutes to allow alternator to come
up to the proper voltage.
Use the (+Up) and (-Down) arrows to
move cursor to the desired test.

REVIEW/PRINT
5. Remove the 10 mm hex head bolt, lock
washer, and flat washer from the negative
side current lead using an 10 mm drive socket.
6. Unthread both cable strain reliefs from the
tester, and pull both cables out of the tester.
7. Remove rubber insert from both threaded
fittings on tester.
8. Cut off the small plastic fingers from both
threaded fittings using a wire cutter.
9. Insert cables through threaded fittings.
Fittings have a slot on the inside to clear
the terminal. Align the terminal with the
slot when inserting the cable through
threaded fitting.
10. Continue installing replacement cable and
clamp assemblies in reverse order of
removal. Note hardware assembly order.
(Fastener, lock washer, then flat washer)
11. Tighten hardware. Recommended torque:
A. 8 mm & 10 mm hex head screws: 22 IN. LBS.
B. Phillips head Volt lead screws: 6 IN. LBS
