Alan the voltage output dropped to less than 7 volts because the armature was
stuck against the cutout coil in the voltage regulator. My terminology comes
from the service manual . The rotor is fine and the ignition is set correctly
(50 BTDC-static set). The problem is in the voltage regulator because when
the armature is pulled from the coil in the regulator the voltage output
returns to above 12 volts. The armature vibrates in the regulator to produce
an average pulsating DC voltage of between ~12 and ~15 volts. If it sticks
against the cutoff coil then the voltage dro[ps to the point that there is not
enough voltage to fire the plugs. Any how thanks for the tip because I did
check out the rotor.

[Healeys] Problems with voltage regulator
Maurice -
Your terminology is a
bit vexing, but if I understand you correctly,
nothing in the Voltage
Regulator should cause your car to stop running
if it is at idle.
Your
problem is elswhere - first thing to check is to replace your
distributor
rotor with a rotor that you know works. There are many
bad rotors in healey
land, and this sounds like a bad rotor.
