What is the voltameter actually measuring? Is it battery power, or alternator power? If it is battery power, does the lower reading on the dial indicate a battery going bad? Or, if alternator, are the needle fluctuations merely reading varying loads and the battery and alternator is ok? -Bob.

According to my dealer...

According to my dealer some fluctuation is normal and nothing to worry about. But, my "usual" reading around level 14 sometimes dips to below nearer 12 when running and stays there.. is this a problem or not? Or, WHEN does the dial indicate a problem that should be rectified by the dealer? -Bob.

Sure it makes sense, but..

Sure that makes sense, but to a layman under practical working circumstances.. WHEN should I be worried my battery or alternator needs looking at? In other words, do I not care how low the needle on the dial reads, unless the warning light comes on? -Bob.
