Did you check your charging system? All battery connections clean and tight? Use digital multimeter across battery posts, everything off, what is the reading? Also, check for excessive battery drain. With everything off, the drain shouldnt exceed 50 ma. That is a generic spec, .050 miliamp not even a tenth of an amp. If the drain is too much, pull/replace fuses one at a time. When you pull the fuse on the problem circuit, the drain returns to normal.
