Gilbert,
Check this out: http://www.batteryuniversity.com/partone-13.htm
Based on this, the minimum charging voltage for a 12V (6-cell)
battery is 13.56V. Looks like you're just below that @ 1,000RPM,
but you'll probably charge OK at higher revs. I'm guessing this is
typical for a Healey, but I don't know for a fact (anybody?).
If you used a DVM (digital voltmeter), the reading may be a bit
low--closer to RMS--because the output of the generator (dynamo)
is "ripple-y" (not a smooth, straight line on an ocsilloscope).
Just for kicks, set the DVM to read "AC," then multiply the result
by 1.4 (or divide by 0.7) and see what you get.
