It's a 1993 Sierra with 350 and auto trans.

The truck has mainly been sitting for the last year.

Last weekend the 1 year old alt stopped charging so I returned it for another one from O'reilly.

The new one is charging just above the red mark on the gauge.

Is this OK or normal? It used to always stay right in the middle of the gauge.

Thanks for any help or info.
