Mechanics - help needed

Not to knock on Autozone's good name int he parts bisuness, but its entirely possible you got some back picks of the litter. I take it the belt is in good shape?

It may be hard to determine if you have a drain somewhere. Problem is, in most cars today, they all have a drain on the battery as normal. For instance. the radio, ECM, and various other computers like the one of the antilock brakes often need some juice.

What I used to do was disconnect the negative battery cable, and connect one end of a test light to the terminal, the other end to the the cable end, if it lit, you had a drain somewhere, if it didnt, then you dont.
