12 V coil, no external resistor needed

I installed a 12V coil when I changed
my Jubilee from 6V. I was with the
understanding that I would measure
about 7 to 8 volts on the negative
side of the coil (the side which connects
into the distributor). This coil indicated
in writing on the side that it was not
necessary to use a resistor or resistance
wiring. I am measuring 12V to the distributor
and worried about eventually frying my points and condenser. Can anyone tell me
why I am still measuring 12V with this coil?

Also, has anyone converted to the electronic
ignition system as sold by Genesee? How do you like it?

As for the electronic ignition, I have never heard a single complaint (outside the price). I can't think of a single car-maker that still uses points and condenser, and the main reason for that is RELIABILITY. E-ignition eliminates corrosion affecting the spark. Lawn mowers? I think it was Toro that guaranteed their mowers to start on the first pull, and the main reason they can do that is the electronic ignition.

-So, I guess that I am just waiting for starting to become a problem before I change over...
