Help with a miss and voltage drop

Well, You haven't blown any fuses or fusible links yet, but it could be an intermittent short in the alternator. That happened to My Pop's '86 Horizon, it blew a link on His way
home from work, He got it rigged w/an inline fuse but would pop out of the blue. The car would shut down immediately, so I followed and We hot wired it and it sailed home.
After some lengthy checking it reared up it's ugly head, one of the wires came loose and exposed in the rotor, it would ground to the rotor body just for an instant.....but
that's all it took. The car was maybe 3 1/2 yrs. old & maybe 50K mi. or so..............just a thought if nothing obvious turns up................................
