Battery light 2007 e320
2007 e320 w211 has 1 battery.
I have a 2007 w211 e320, the battery light is on, convenience features, ac compressor kicks off.
Water got into my from SAM / fuse box from a car wash and shorted it out. Starter engaged and stayed engaged until starter burned up and then SAM continued to smolder.
Had SAM replaced and starter replaced. Cranks and runs fine, except Battery light symbol comes on after about 10 seconds at start up, and then ac compressor kicks off.
I replaced alternator, thinking the overload/short had fried the regulator.
Light still comes on, ac still kicks off.
Pulled up voltage on dash display, 12.3 at start, climbs to 14.2 , then battery light comes on.
I swapped batteries, nothing changes, not a bad battery.
If I pull the plug on the battery sensor, on the negative terminal, nothing changes.
When the SAM shorted out and the starter stayed engaged, the battery terminal and cables got very hot.
Could this have fried the battery sensor?
Any help would be appreciated
