I have a 1995 Chev pu Z71, 6.5 Turbo Diesel with chronic battery problems. 2 - Side post batteries. The lights will burn, the soleniod will click but the truck will not start. Batteries checked at NAPA were good. I cleaned the post and cable ends and that worked for about 2 weeks. Replaced the battery bolts but not the lead spacer between the two cable lugs on the main battery post. I'm thinking I should have. Anyway she is dead again. This time the the positive cables on the main battery will spin around on the bolt but the bolt will not break free from the battery. Thanks in advance for any suggestions.
