ELECTRICAL

CHARGING SYSTEM
WARNING
CURRENT DRAW - KEY OFF Never start the engine with an ammeter connected in
series. Damage to the meter or meter fuse will result.
CAUTION Do not run test for extended period of time.
Do not run test with high amperage accessories.
Do not connect or disconnect the battery cable or
ammeter with the engine running. Damage will occur to
electrical components. 1. Using an inductive amperage metering device, (set
to DC amps) connect to the negative battery cable.
Connect an ammeter in series with the negative battery 2. With engine off, key switch and lights in the on

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