Nope, runs fine for awhile.  ISTR it was several hours before the point rubbing 
block melted.

And I disagree with Darrell, it won't generate any more output unless your 
battery voltage is way down or you are running at high
rpm.  Once the core saturates, the excess current just gets wasted as heat.

As I've mentioned before, a ballast resistor is reasonably cheap at any FLAPS.  
If you need to use a 1.5 ohm coil for whatever
reason, just stick a resistor in series with it.  If they insist on knowing the 
application, tell them it's for a 68 Dodge Dart with
a 225 slant six.  RockAuto has them for a whopping $2.50 <g>
