Please help!/ electrical

Im haveing a lot of trouble getting through this disaster. Heres how it started. I started my car one day and it died out. I saw smoke comeing up from under the hood. I quickly jumped out and popped the hood up and saw that the wire was burnt out for the ecc. so the car wasnt getting fuel or spark. I replaced the wire with a fusible link but every time i start the car it burns out the fuse. I checked all of my connections and everything is solid. i went over the wire with a tester to see if their were any breaks in the line. I fallowed it back to the alternator. After i took the alternator off i saw that some wires were bent at an angle that looked as if it was causing the problem. I unbent them and reasembled everything and the car started right up. I took it for a testdrive around the block and it died right out on me. Im scratching my head and frustrated, it's a 91 mustang w/ a 95 motor and ive owned the car for 2 months.

its a yellow wire off of the ignition, today i took the clip off the alternator to make sure it wasnt the alternator since it was getting very hot. It started up and then stalled out after i took off an let off the clutch. Theirfor i thought something was hitting the clutch and grounding something out. But i checked under the dash and everything was okay. It drives for a little before it blows the fuse

Just curious is the yellow wire off the starter relay a ground wire? I tested it w/ a pwr/ground test light, their was no power but it had ground. I also changed the fusible link w/ a straight power wire ( since it was constintly blowing fuse's) and it burnt up the wire.
