TEST
TESTING PROCEDURE IMPORTANT
1. Remove the negative cable from the battery. Do not allow the battery cables to become
disconnected with the engine running. Follow the steps
2. Connect a jumper from the negative battery cable
terminal to the negative battery post. below as outlined to reduce the chance of damage to
electrical components.
3. Ensure your meter leads and selector dial are set to
measure amperage. The “break even” point of the charging system is the
point at which the alternator overcomes all system loads
4. Connect your red lead to the battery negative cable
terminal. (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.

WARNING
Never start the engine with an ammeter connected in
series. Damage to the meter or meter fuse will result.
Do not run test for extended period of time.
Do not run test with high amperage accessories.

1. Using an inductive amperage metering device, (set
to DC amps) connect to the negative battery cable.
2. With engine off, key switch and lights in the on
position, the ammeter should read negative amps
(battery discharge).
5. Connect your black lead to the battery negative post. 3. Shift transmission into park and start the engine.
With the engine running at idle, observe meter
readings.
