Somebody help me out here on deep-cycle batteries killing alternators. I've owned two old police cars that came with Delco deep-cycle marines batteries and never replaced an alternator, although they were, admittedly, the size of a bushel basket.
My convertible (9.5:1 455) has a 100 amp alternator I had a local guy modify to one wire.
Given the fact that modern voltage regs are just an off/off switch, I fail to see how the battery could affect the charging system.
Your thoughts, gentlemen?
