So many posts under the lack of good spark. For the sake of sanity lets talk of a 12 volt side distributor 8N, although other N's can be related to the topic.
It seems the well respected recommendation of the Napa internal resister coil (ic14sb) is the go to coil. And for points it is the Napa (ics749). All is good so far, but little is said about the condenser #.
When looking up car condensers applications there are dozens of different numbers, which leads me to believe they are [u:a19aac55c6]very vehicle specific[/u:a19aac55c6], based on voltage/amperage and coil used.
So given the objection of the condenser to keep the points from arching and burning along with helping the collapse of the primary windings in the coil.
I would think the capacity and selection of the condenser to be very important, and given the large number of posts about burnt points, poor spark and hard starting problems very relevant.
So for those in the know, what number condenser do you come up with for the 12 volt conversion and what do you base that selection on? Also, have you had long term success with that selection?
Thanks Bill
