Just to get an idea of the Alternators condition, get to the engineering page (while starting the engine) Then scroll down to the displayed battery voltage page. A good Alternator would show something like 14.7 volts +/- a little (or you may even have a full time voltage readout gauge in your car to view). If it just displays the *existing/current* battery voltage, that would be a good indication that the Alternator has taken a dive on you. There have been several that have lost their Alternators over the years (including me). Will start poking around at various sources for either a new OEM Alternator or an aftermarket version, an (if I find something worthwhile), I'll add some info to this post.
Not sure if a rebuilt or after market new units actually work as intended. For now as a reference point, a new GM OEM unit P/N 92173959 from Amazon goes for $158
