Janicholson said: (quoted from post at 17:39:48 11/03/09) The spark is a connection. It is connected with wire to the electrodes, and across the electrodes by way of the ionized gasses in the spark to ground. Does it do so -- yes.
I admit the conduction through the resistor as valid, I would not deny it exists will it make a usable ignition spark I guess it might be operational to a degree, I would not put an ignition together that way.
Spark is often created by turning off the key and collapsing the system. Sometimes causing a terrific backfire. Where is the connection to the resistor then!!! JimN
"Ign key....where is the connection thru the resistor then?" The connection at that time is thru the arc across the contacts of the opening key switch....the exact equivalent of points opening in the absence of a condenser....still get a spark, although a weak one, since so much of the energy stored in the coils magnetic field is turned into heat in the arc across the opening switch or points instead of passing to the HV circuit. With the condenser, not as much "sharing' takes place , with more going to the HV and less lost at the points.
