If the lamps are BAT - PARKING - BULB OUT - BRAKE FAIL then the symptoms fit brushes or regulator in the alternator. I don't know how the ABS ties in to the brush or alternator problem, except that it might be an early warning of low voltage.
If not the brushes, the small red wire you checked at the alternator could be damaged where it disappears under the alternator and crank pulley, shorting to ground as the engine moves in its mounts, however I'd think that was less likely in your 93.
Pull out the brush/regulator assembly and inspect the length of the brushes. You can do this without removing the alternator if you have a #2 Phillips screwdriver with an unworn tip. Also, with a flashlight, check through the hole it leaves to see if the alternator slip rings are in good shape. You can spend very little to repair this, if the brushes are just worn. Check out the 7/9 FAQ for more detail, such as length of brushes and how to replace them.
I was trying to connect this with your visit to Walmart, but can't seem to do so.
