Current Draw - Key Off; Charging System "Break Even" Test - Polaris Hawkeye Repair Manual

CURRENT DRAW - KEY OFF

CAUTION
Do not connect or disconnect the battery cable or am-
meter with the engine running. Damage will occur to
light bulbs and speed limiter.
Connect an ammeter in series with the negative battery cable.
Check for current draw with the key off. If the draw is
excessive, loads should be disconnected from the system one
by one until the draw is eliminated. Check component wiring as
well as the component for partial shorts to ground to eliminate
the draw.
Current Draw - Key Off:
Maximum of .02 DCA (20mA)
CHARGING SYSTEM "BREAK
EVEN" TEST
CAUTION
Do not connect or disconnect the battery cable or am-
meter with the engine running.
CAUTION
Never use the electric starter with an ammeter con-
nected in series, as damage to the meter or meter fuse
may result. Do not run test for extended period of time.
Do not run test with high amperage accessories.
The "break even" point of the charging system is the point at
which the alternator overcomes all system loads (lights, etc.)
and begins to charge the battery. Depending on battery
condition and system load, the break even point may vary
slightly. The battery should be fully charged before performing
this test.

Do not use electric start.
• Clamp an inductive ammeter or connect an ammeter (set
to DC amps) in series between the negative battery cable
and terminal.
Current Drain Inspection
Key Off
Less Than 9 mA
• Connect a tachometer according to manufacturer's
instructions.
• With engine off and the RUN/OFF switch in the RUN
position, the ammeter should read negative amps
(battery discharge). Reverse meter leads if a positive
reading is indicated
• Shift transmission into neutral and start the engine.
• Turn headlight on, and apply the brake light. Increase
engine RPM while observing ammeter and tachometer.
• Note RPM at which the battery starts to charge (ammeter
indication is positive).
• With lights and other electrical load off, this should
occur at approximately 1500 RPM or lower.
• Turn the lights on and lock parking brake to keep brake
light on.
• Repeat test, observing ammeter and tachometer. With
lights on, charging should occur at or below 2000 RPM.
