Except that the readings they are showing are not correct for our cars. The 
A-series cars use internally-ballasted coils and should read about 3 oms 
across the primary and the later 1500 cars use externally-ballasted coils 
and should read about 1.5 ohms across the primary. Not sure the exact 
changeover. Never checked the secondary...
