It seems to me it is indicating you are running on the battery which means your generator is not putting out (by it some wine)

Ammeter. Refer to the below figure.
Troubleshooting the ammeter
circuit can be difficult. The following
applies to cars equiped with alternators.
In the Chassis Service Manual there will be a simplified diagram of the
charging system similar in part to that show above.
Possibly the biggest mistake
that people make associated with the ammeter circuit is not turning the
ignition switch to either ACC or ON when trying to decide if the ammeter is
showing proper discharge. You can
perform the following test and see if it makes a diference. Start the engine and let it run for a few
minutes until the ammeter reads close to zero.
Shut off the engine and with the ignition switch OFF, turn on the high
beam lights. Make a note of the ammeter
reading. Turn off the headlights. Turn
the ignition switch to ACC and again turn on the high beams. The amount of discharge shown by the ammeter
should be about twice, or more, what it was before.
By referring to the above
diagram, it can be seen that the ammeter reads the difference in voltage
between the battery and the alternator.
The wire that goes directly from the battery to the alternator and
appears to short out the ammeter is a meter shunt. What the ammeter actually reads is the
voltage drop across this wire. The
resistance of this wire is about 0.1 ohm.
There is no physical resistor in the circuit, the resistance is due to
the length of the wire required to get from the starter solenoid to the horn
relay around the engine bay.
The horn relay is not in the
ammeter circuit but is a convenient connection point for the alternator output
and the voltage regulator.
When the output voltage of
the alternator is greater than battery voltage, the ammeter shows a charge proportional
to the difference in voltage. When the
battery comes up to full charge, the ammeter drops to near zero. If the output of the alternator is less than
the battery voltage, as under a heavy load, the ammeter will show a discharge
proportional to the difference in voltage.
The voltage regulator is set to have a voltage slightly higher than the fully charged voltage of the battery so that the alternator will carry most of the vehicle loads and maintain a slight trickle charge on the battery at all times the engine is running. Under normal conditions, the ammeter will show a slight charge when the engine has been running for a few minutes and the system is working correctly.
