Aluminum oxide is the demon. Aluminum stud, aluminum nut & aluminum braided cable, engine body ground. removed from firewall cleaned put back no gremlin. If the problem is at the block (hard to get at) just run a 14 - 16 gauge copper wire from stud to block, alternator bracket has a 8 mm bolt holding a wire clip (that was first thing I did), stopped in the middle of no where after gremlin attack dash gauges door locks headlights warning lights radio clock reset. Went to start turning key nothing at all. Key in the on position with a coat hanger touched body ground bolt and block the key in ignition alarm started dinging. used a lamp cord that was in the bed stripped it rigged it up and no problems rest of 30 miles home. once home pulled ground strap from firewall cleaned with wire brush reinstalled not a flicker from headlights when brakes are applied nothing demon/gremlin completely gone.
