#1

Check Battery light came on, initially only when it was very hot (of course for the past few weeks it’s only been very hot). Had the charging system checked-they said I needed a new battery-replaced the battery-light’s still on. Before and after changing the battery-the systems’ voltage has been around 14.2 whether the light is on or not.



Anyone have any thoughts?

This kind of trouble is usually related to a problem with the alternator. There may be a bad diode inside it causing the trouble.


#3

A check of the ground connections, and cables, and connections is the first place to start.
