You seem kind of new at this, so here is the deal: The points are simply a switch that allows current to flow through the primary windings of the coil. The dwell is the the number of degrees of rotation of the distributor shaft where the points are closed and the current flows, the amount of TIME the points are closed varies with engine RPM. Your Petronix does the same thing except it can electronically change the dwell in relation to the engine RPM to make the coil work more efficiently. Works like this: points close, current (12v) flows through coil primary windings (few) to ground, building up a magnetic field. The points open, current stops and the field collapses. The collapsing magnetic field generates a high voltage (20,000+) in the coil secondary windings (many). The HV flows through the coil high voltage wire to the center of the distributor down through the carbon button into the rotor contact, where if your timing is correct it jumps over to the pluge wire contact, travels through the plug wire to the plug where it jumps the gap to ground and the plug fires. So as Dennis said, yes LOL.
