a bad ground wire can ruin an alternator by not completing the circuit
There is no ground wire.... it grounds through where it touches the engine
Refer to your service and user manual on how to change an alternator ground wire on a 1994 Mitsubishi 3000 GT.
Yes, if it shorts to ground internally.
On a dodge alternator the two small wires go to the voltage regulator . It doesn't matter which wire goes where, but the red or blue wire needs 12 volts when the key is on. The green wire goes directly to the regulator from the alternator. The large wire goes to the battery and it is important that you don't undersize this wire. The other wire is a ground wire and can be grounded to the block or not used as the case is grounded by the bolts that hold it on.
That particular wire is usually 10 gauge.

Is the alternator a known good one? You could have a bad rectifier in your alternator causing a short to ground when it is installed.
I assume the wire in question is the smaller blue wire. Yes it travels inside the car to the central electrics (fuse block) then to the instrument cluster. The cluster feed the battery light power and finds a ground through said wire at the alternator. when the alt starts charging, there is power on that wire from the altwhich doesn't let the bulb get ground and the light is out.
You do not connect any wire from the alternator to the starter. The positive wire from the alternator should run to the positive on the battery, and the negative wire (if equipped) should run to the engine block (or any suitable ground). Most alternators are already grounded by the bolts holding them to the engine, but some do have a negative wire.
You have to disconnect the ground wire from the block. You have to disconnect the positive wire from the starter and the alternator and the powerline going to the fuse box. and connect the new ground then the positive
