1993 Honda Accord car wont start

I was driving my car when I noticed that the speedometer and the rest of the gauges were fluctuating and then stop working all together. Soon after the car began to lag so I pulled over to check and when I was pulling up to the curb it died. I tried starting it but didn't start it wouldn't even crank the only sound the car made was a single click when I checked the engine I noticed the wire that connects to the alternator was burned as if damaged by a high voltage spark. Before this I changed the distributor cap, ignition wires, timing belt, and bought a new alternator. There is no check engine light or anything. I also noticed that my battery was drained so the next day I brought a new fully charged one but it still didn't start so I removed the alternator to get it tested it passed and the following day I returned installed the alternator and when I checkedthe battery it was drained again. I thimk it might be the starter but It shouldn't kill the car right. Buty question is what's wrong with my car? Hopefully that was enough detail.
