Do you have the owner's manual?
You can try Google.

The charger is for older chemistry ni-cad batteries.
The third wire is more than likely to sense battery temperature.
NO, do not short any wires or connections.
How do you know that the charger is faulty and not the OLD battery?. Have you tried charging another battery?.
