Unfortunately the ammeter is the weakest link in the circuit from the battery to (say) the lights. If you get a short-circuit somewhere it will usually be the weakest link which blows. So please do fit an inline fuse between the battery and the ammeter, so that if something electrical goes seriously pear-shaped it will be the 50p fuse that goes rather than the valuable ammeter.
