CAUTION Never start the engine with an ammeter connected in
series. Damage to the meter or meter fuse will result.

shorts to ground to eliminate the draw.
3. Shift transmission into park and start the engine.
With the engine running at idle, observe meter
readings.
4. Increase engine RPM while observing ammeter and
tachometer. Note the RPM at which the battery starts
to charge (ammeter indication is positive).
5. With lights and other electrical loads off, the “break
even” point should occur at approximately 1500 RPM
or lower.

CHARGING SYSTEM STATOR
(ALTERNATOR) TESTS
Three tests can be performed using a multi-meter to
determine the condition of the stator (alternator).

Current Draw - Key Off:
Maximum of .01 DCA (10 mA)

CHARGING SYSTEM “BREAK EVEN” TEST

CAUTION
Do not allow the battery cables to become
disconnected with the engine running. Follow the steps
below as outlined to reduce the chance of damage to
electrical components.

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 11
on battery condition and system load, the break even
point may vary slightly. The battery should be fully
charged before performing this test.
