The answer to your question is yes.

The ammeter sits between the two terminal studs on the fire wall connector. It is essentially a direct connection between the two studs. The ammeter has what is called a shunt that is a brass sheet of material that is a dead short between the two terminals. The shunt allows the lion share of the current to flow through it, but it is calibrated so that the voltage drop across it is read by the meter as the total amount of current passing through the meter.

Hook a wire across the two terminals and it will eliminate the meter.

so the very small amount of current passing through the meter movement will register as the total amount of current passing through the meter.
