Re: coil questions
The modern coil fires only once at the precice time that the circuit is opened. It will not fire continuously like a buzz coil. Left connected continuously most modern coils will overheat & burn out.
A modern coil relys on DC current to operate.
The roller arrangement in a T timer probably does not have a clean enough break in the circuit to fire a modern coil with good results.
The condenser is necessary to cause the spark to be produced & it keeps th points from burning as well.
The True-Fire system does indeed use very modern coils but it is triggered by a modern magnetic pick up that replaces the timer.
All in all it is hard to beat the original system that works well when set up any where close to correctly & can be convinced to get you home in the event of trouble with the extra coil that usually rattles around under the seat & a few wooden matches stuffed in just the right spots to make the contacts work.
