This morning I had a car in for service-2015 with 200k km/124k miles. The battery was pretty ugly so I sprayed it with battery cleaner and hosed it off. The driver just came up saying the battery light is flickering. Started doing it a little this morning and it's not more constant. Looks like it's been charging between 14.4-15.5 volts. Seems a little high, most of the other cars in the fleet look to be between 13.6-14.3 while running.
I replaced the positive battery clamp as it was pretty fugly, no change. Then figured I'd try playing mitsubishi service department derp and just threw a different alternator on it with no change again. Might have to clean up all the connections at the positive terminal a bit better and see if that makes a difference.
Edit: I believe this is the same car that's been going through headlight and tail light bulbs like crazy compared to all the other's.
