An ideal Voltmeter will not drain the battery at all. I am sure the Autometer
is a pretty darn good Voltmeter (better be for the money!). But it will
not have an infinite inpt impedance so a little current is going to flow.. It
probably won't drain the batt anymore than the clock. but... For some
reason I jsut don't like the idea of it being 'on' all the time. I guess its
the
same reason why I went to all this trouble to make the stock temp gauge
work...eventhough I know its not terribley accurate...
Is switching the ground side of jsut one thing really all that bad??
