At higher rpm's there is less time for the energy to build up between
firings, so a high resistance (in the ignition circuit) would be a
greater problem at high speed not better.
I missed the bit about changing the coil, sorry.
I would have to go for the lower voltage at idle, but even a dynamo in
good condition should produce a maximum voltage difference between idle
and full speed between 12 to 13.8 volts.
The Kettering ignition should not be a huge burden for any electrical
system (approx 2 amps max. during dwell).
The PerTronics setup seems to be merely a Hall effect type of points
replacement with roughly the same current characteristic as points. It
just switches much faster, producing a fatter spark.
I did come across a mention of installation glitches in s Bosch dizzy.
Not sure if it may be relevant here ...
