Codes and Charging issues

[wrl799]

Start off with what started the problems, battery died, replaced with new. I had a drain on battery before going thru one every couple of years. So two days later ,turn over key, Click. Bring it to indie and finds nothing. Drive it for two days, Click, drive it home in limp mode.Cleared Next morning, Click, on meter charging 13.6v running, down to 12.8v, turn off and 11.7v. I took neg cable, test light on, checking all fuses and relays. No findings. Next morning, Click, try to jump it to take to indie, and no click at all, stuck in park, had to tow to indie. Sorry so long. Now the codes, B1010,1040,1041,1086,1089,1088,1716,1788,1858,1784 ,1040. Replaced AAM module aproxx 3 yrs ago from a yard in tenn. Any help, Thanks Bill
