Battery keeps dying

[Patrick L.]

Like CZ mentioned, it appears there might be a draw somewhere. After shutdown what does the ammeter show ? Does it show a discharge ? A common culprit is the stop light switch sticking on. Disconnecting a battery terminal and putting a test light between the post and cable end will show if there is a draw if the light lights. If the light lights you do have a draw, keep disconnecting things until it goes out, that'll be the problem.
How much charge are you showing, I don't like to any more than 12 amps from a little ole 'A' generator. 8-10 should be more than enough if driving at night quite a bit and 2-4 if not driving at night very much.
