1967 Camaro Electric Problem

Hi all, first time to the post and I was wondering if anyone out there can help me out?

I seem to have a issue with my charging system or wiring in my 67 camaro , seems that I am not getting a charge back to my battery and I am not sure why. I recently went to auto zone and got a new voltage regulator (not internal to alternator), I also today - got a new horn relay just to make sure I closed the loop with no issues.
My battery is reading a healthy 12.2 volts when running and the alternator seems to read about the same when running.. But when I run the car like I did last night for about 60 miles - she died at idol and would not crank until the next day after I charged the battery.. I had the alternator tested and it seems to be in check - tested at 14 amp...

The generator light is on inside on the dash and seems to go on and off.. But for the most part stays on??

What you guys think AM I really in some troubles here or is ti something really small and stupid I am over looking?

get out your dvom, set to DC volts, in the 20v range, 1 probe touch to the alternator output wire ( red, 8ga wire can't miss it ) and the other touch to the positive side of the battery, should read 0 ( tests voltage drop ), if it reads a number, your loosing that many volts going back to the battery, if it says 12v your not charging. next, set your dvom to AC volts, in the 1v setting, tocch 1 lead to the alternator body, and the other to the alternator output, should read less than .500 volts, if it's over 1 volt, the bridge rectefier in the alternator is bad, which is the diodes.

Number 1, if your battery and alternator are reading 12.2 volts when running the alternator isn't charging.
Number 2, the horn relay has nothing to do with the alternator charging.
Number 3, if the alternator is putting out 14 AMPS when it was tested it's junk. It should be putting out 14 volts and probably 68 or so AMPS.

Doc Here,

Do you get a Battery Lamp at ANY TIME at all? (like before you start?)

if you are reading 12.2V on a V guage wired into the dash harness...fair to good chance it is not telling you the correct V output at the alt to the batt....

turn the idle up to about 1200 and read the V across the batt terminals, should be min 13.4 max 14.4 if the alt is working

very common for old harnesses to loose 1-2V due to shot/corroded/butchered/etc wires and connectors and grounds
