Easy test. Pull the small red (D+) wire from the alternator and fashion a jumper clip to ground the end of that wire on something reliable (not the case of the alt). Get back in the car and turn the ignition switch to KP-II. If you see the usual warning lights on, but only sometimes when you wiggle the key, then you can bet the 28-year old switch has given up its life. If the lights come on solid, the alt has what it needs from this wire. If they don't come on, the trouble could be in the cluster or, very rarely, the key switch failed completely, in which case you probably can't make the motor run after a jump.
