Not sure of brand. Small body and cap like point type. External gm type module, mounted under cover on outside of dist. Thought this might be an issue. But in my mind, module and dist triggers spark and delivers via plug wire. It seams to me, now correct me if my thinking is wrong, this would result in a no spark senario. I did check rotor button, and cleaned rotor tip and brass contacts in cap. Spark travels from coil thru coil wire to rotor button thru brass to rotor tip to corisponding term on dist cap thru plug wire to plug. The dist does trigger spark. So am I thinking correct?
