My guess is that the brushes on your alternator started making intermittent contact and that is why your tachs bounced because they pick up their rpm signal from the alternator. Then they finally failed. Ten volts won't do any charging.



So yes get your alternator checked and rebuilt if necessary. A good automotive electrical shop can do it.
