When the light was on idle was 850?
Yesterday I fiddled with the wires and it has basically been off since. When I put the alternator in there was the main wiring harness and then there was a separate black/white wire. I broke the gray connector for that wire and had to splice a new one in 4 years ago. I noticed when that wire is disconnected the BAT light comes on. I fiddled with that wire yesterday. I am not sure what that wire is for. I am still putting out 14.52ish. It is 1 degree F outside. I hope it lasts a few more days or maybe it was the black/white wire
