have a 86 mustang standard, 2.3 engine....replaced starter, solinoid, regulater, battery last night, and alternator today.. when you turn the key it just clicks like a dead battery. wont turn over , now get a rapid click when i turn over the key but wont start... only thing that i can think of now is the battery cables, replacing ground tomorrow, positive looks good... any other suggestions, was running ok until alternator went last night ... stuck now on where to look
