Current Draw - Key Off:
Maximum of .02 DCA (20 mA)
1. The “break even” point of the charging system is the
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
charged before performing this test.
2. Clamp an inductive ammeter or connect an ammeter (set to
DC amps) in series between the negative battery cable and
terminal.
3. Connect a tachometer according to manufacturer’s
instructions.
4. With engine off and the key and kill switch in the
ON position, the ammeter should read negative amps (battery
discharge). Reverse meter leads if a positive reading is
indicated.
5. Shift transmission into neutral and start the engine. If using
an ammeter in series, start engine with kick-start only.
6. Turn headlight on high beam and apply the brake light.
Increase engine RPM while observing ammeter and
tachometer.
7. Note RPM at which the battery starts to charge (ammeter
indication is positive).
8. With lights and other electrical load off, this should occur at
approximately 1500 RPM or lower.
9. Turn the lights on and lock parking brake to keep
on.
10. Repeat test, observing ammeter and tachometer. With
lights on, charging should occur at or below 2000 RPM.

◎ ALTERNATOR OUTPUT TEST (AC AMP)
This test measures AC amperage from the alternator.
This test simulates a “full load” on the
not perform this test longer than required
reading or the alternator stator windings may
overheat. Do not exceed idle rpm during this test.
To Calculate Available Alternator Output
I=P/E, 150W / 12V = 12.5 Amps I =
I = Current in Amps
P = Power in Watts
E = Electromotive Force (Volts)
Alternator Current Output:
Minimum of 5 AC Amps
1. Maximum alternator output will be indicated on
is not necessary to increase engine RPM above idle.
2. Place the red lead on the tester in the 10A jack.
3. Turn the selector dial to the AC amps position.
4. Connect the meter leads to the wires leading from the
alternator (see schematic for proper wiring colors).
5. Start the engine and let it idle. Reading should be a
minimum of 5A at idle.

◎BATTERY IDENTIFICATION
NOTICE: It is important to identify what type of
battery you have installed in your ATV. Different
types of batteries require different service
procedures.
Proper servicing and upkeep of your battery is very important
for maintaining long battery life.
Your ATV may have a Conventional Battery or a
Sealed Low Maintenance Battery. To identify which type of
battery your ATV has, refer to the illustration below and
follow the correct service and charging procedures that follow
in the manual.
