Regulated Voltage / Amperage Output Inspection - Victory Cross Roads Classic Service Manual

BATTERY CHARGING SYSTEM
Battery Conductance Analyzer
Conductance describes the ability of a battery to conduct
current. A conductance tester functions by sending a low
frequency AC signal through the battery and a portion of
the current response is captured, from this output a
conductance measurement is calculated. Conductance
testing is more accurate than voltage, specific gravity, or
load testing.
Authorized Polaris dealers / distributors are required to use
the conductance analyzer when testing 12V Polaris
batteries.
Regulated Voltage / Amperage Output
Inspection
1. Remove center chin fairing (page 16.3).
2. Remove negative battery leads and connect a 12V
shunt as outlined in the instructions provided with
shunt or use an inductive amperage clamp.
NOTICE: Current can easily exceed the measuring
limits of your ammeter or its internal fuse.
An inductive ammeter clamp or a suitable shunt
must be used to avoid meter or fuse damage.
Voltage
3. Set digital multimeter (DMM) to V DC scale.
4. Connect DMM red (+) lead to battery (+) terminal and
DMM black (-) lead to battery (-) terminal.

5. Start engine and warm to operating temperature.
6. At 1000 RPM or slightly above; the ammeter should
reach the "break-even" point (no amperage leaving the
battery).
7. The voltmeter should be rising toward 14 VDC.
Specification:
8. Increase engine RPM to 2500. The ammeter should
rise a slight amount, then stabilize. Volt meter should
read above 14 V DC.
9. Use results obtained from preceding tests and the
following descriptions to determine if charging system
is functioning properly.
CHARGING
Ammeter goes up a small amount, then stabilizes slightly
above +0 amps. Volt meter rises toward 14.8 V DC, drops
off a little and starts to stabilize.
LOW BATTERY:
Amperage continues to rise, voltage levels off as battery
is absorbing voltage. Need to charge battery fully or use a
good battery and repeat test.
CHARGING SYSTEM UNDERCHARGING:
Ammeter drops to 0 or remains below 0 (negative
reading) at all rpm, volt meter remains the same or goes
down. Go to voltage drop inspection.
CHARGING SYSTEM OVERCHARGING:
Ammeter rises well above 0 and remains there or
continues to rise. Volt meter goes well above 14.8 V DC
and may continue to rise. Go to voltage regulator/rectifier
inspection.
EXCESSIVE LOAD:
Amperage levels off or starts to drop, voltage continues to
rise. Load may be excessive (accessories or shorted
components). Determine if excessive loads are present
(disconnect accessories and re-test).
10. Turn ignition key off.
11. Remove ammeter shunt or inductive clamp.
12. Re-connect negative battery cables to battery.
13. Install center chin fairing.
