How can I test an ammeter? In the car is not an option as the car has no wiring in it or lights etc.

Take a flash light battery and connect it across the terminals it should move.

Hook it in series to a globe.

Yeh .

Ammeter don't matter about voltage or polarity to see if it works.

6 or 12 battery pos or neg.

1 wire from batt to one side of ammeter.

1 wire from other side of ammeter to one terminal of headlight globe.

1 wire from other side of globe back to batt.

Example...12 V battery 55 watt globe should make the ammeter go to 4.5 amps.

If you just guess any wire, you have a 50/50 chance it will show 4.5 charge or discharge.

It don't matter, it is just a test, and if it works one way it will work the other.

Just swap wires.
