[OMC-Boats] Volt Gauge wiring.

Had another test run yesterday with disappointing results.  I'm still having performance issues which I will list those out in an email later this afternoon

In the meantime, I have a question related to my new alternator and the new Volt gauge on the dash.  As part of my restoration, I replaced the original gauge set with an expanded set from Faria.  Nice looking, white background, yada, yada, yada....  The original dash had an AMP gauge, the new one a Volt gauge. 

On a car, the Volt gauge shows charging and discharging.  When charging, it shows clearly over 12v and when discharging, it shows clearly below 12v.  My new volt gauge shows consistently 11-11.5volts.  If I hit a switch on that dash it will flicker downward but other than that, it doesn't show more than 11.5v. 

Some restart problems after being out on the lake for a while suggested the alternator was not charging up to par so I had it checked and was advised it was bad.  With Lee's help, I found a source for a new replacement alternator and installed that.  The results....the volt gauge still shows a flat 11-11.5volts (gee, was the original alternator really bad as told??).  That makes me wonder if I have the gauge wired wrong and it's just showing the level of the battery as opposed to what the alternator is doing. 

I've looked at the wiring chart that Lee provided which documents an AMP meter setup.  Does anyone have a schematic reflecting a volt gauge or can someone enlighten me as to what the wiring should be like for one?  Maybe I don't have it wired properly. 

Thanks.
