For the past few months intermidently I would get nothing turning the key but a click at the relay. This morning she started like normal, and I stopped for coffee and smokes on my way to work. I sat in the 7-11 parking lot for 2 hours after checking relays, connections at the starter Ect. Finally I grabbed the 5/16" wrench and got a 1/2 turn out of each post. I took both terminals off and cleaned the white crusty crap off and reinstalled... She turned over like new. Hope my miss fortune helps someon
