Hey guys I have a VDO voltometer that i will be installing in my 914.. well, last night I thought I'd make sure it worked before installing it and it would only show 8 volts. The "experiment" was that I just held the thing in my hand and attached a wire from the + side to the + side of my (new-ish) Optima battery, and a wire from the - on the voltometer to the - on my battery. The needle would just bearly bounce off it's resting place to about 8 volts. Did I test it right? Could my car actually be getting me around day-in/day-out on only 8 volts? The Optima is basically new, only had it for a few months but hit the starter a whole bunch trying to get my car to start when I installed my engine. Been driving the car daily for about 2 weeks now.

Charged battery should show 12 VDC approximate....try your guage with a battery charger....If it still shows 8VDC, the guage is in error....if it shows 12 -14 VDC, the Optima is less than optimum.
