I put a new 180 amp alternator on my 2000 camaro it's a base model with a 3.8. The check gauge light stays on now. It's running good and all gauges are showing good. Do you have any idea why. Please help. Thanks
it is saying check gauges because something is reading out of the normal. I know on my 97 3.8 that light would come on if fuel level was low, low oil light came on, voltage gauge out of range, overheating etc.
Never came on for just a check engine light though.
