There is a warning light for alternator on the bottom of the cluster.
What code is present when the check engine light comes on? The check engine light is something else.

When the car is running it reads 12.2 volts. This is about 10 minutes after I topped off the charge on the brand new battery.
I tested the alternator using my smart tester and it said ok, but obviously it is not charging
I don't have the code reader. BUt the last time I ran it it said glow plug relay or pre-glow timing relay.
BUt I tested that and it is fine as are my glow plugs.
