[Mgs] Ignition light always on, low glow

The ignition light on my '71 has been low-glowing for years. I get a solid 
14 volts with the headlights and blower on, so I figure the alternator is 
working fine. The car has a maintenance free battery, I wonder if that has 
something to do with it? I've heard that maintenance free batteries need a 
slightly higher charging voltage. So maybe there's a slight mismatch between 
the voltage of the new tech batteries and the charging voltage of the old 
alternator, that makes the light glow. - Just a theory ;-).
