By "not working", I assume you mean it shows neither charge nor discharge. Your ammeter may not be bad, but lack of indication could be a symptom of the real problem.
Ammeters work by measuring voltage across a shunt. The shunt may be part of the meter, or (typical in autos) it can be remote from the meter. If you have heavy gauge wires going to the meter, the shunt is part of the meter. It the meter movement blows, the shunt will continue to pass current. It's unusual for a shunt to fail (they'll take at least 100 amps), but it's not uncommon for the shunt wiring to break. Also, there's often a fuse or fusible line inline with the shunt. Follow the heavy gauge wires from the gauge back to wherever they go, you'll probably find the problem.
