Hi all, I'm having serious electrical problems with my 87 z. Battery not holding charge; alt replaced and new battery. Told by a mechanic who hit me for a bunch of $$$ that possibly dashboard cluster, or harness. By another mechanic that electrical under pass seat shorted, yada, yada, yada. Does anyone out there know of a responsible, reliable mechanic that specializes on z's in Long Island, NY (preferably Nassau County) that will be able to definitively pinpoint problem. Thanks Art
