You know what I just painted my alternator stand.
Could it be that I am not getting a good ground there?
I will try the ground strap idea before I replace the alternator
The alternator should ground to the engine and the engine should ground to the frame
You can check for grounds with an ohm meter
A bad ground can cause erratic volt readings and cause over heat issues also
Adding extra grounds will not hurt in fact you may find them to help
Clean and tight grounds
