Ammeter reads ZERO. is this correct
An ammeter shows the current coming out of the battery. Once recharged from starting, it should read zero unless you run off the battery (alternator turned off). Typically, these are labeled "charge" and "discharge" with zero in the center. A loadmeter shows the total current coming through the power bus. It should always be positive.

How to Check Battery Amps with a Multimeter
To check the amps of your battery using a multimeter, you need to execute an amp measurement test. This test involves connecting the multimeter in series with the power source and measuring the current flow.
Understanding Charging Systems with Ammeter
The Main Power Wires; Alternator and Battery. Notice the main junction is located between the alternator and the ammeter. When the engine is running, no current from the alternator flows through the ammeter except to recharge the battery. The output wire from the battery also serves as its charging wire.
3 Ways to Connect an Ammeter
For instance, if you have the ammeter between a battery and a lightbulb, the red probe may connect to the lightbulb. The black wire can touch the battery''s negative terminal or a wire connected to it. If you''re working with a battery, don''t connect both probes directly to the battery''s terminals. It may cause the ammeter to burn out.
