1950 8N, 6v., Side distributor, I have little to no spark coming through spark plug wires. Replaced plugs, points, condenser, rotary button, replaced coil 4 months ago with a new coil from O'Reillys. By passed key switch still little spark. Have 6 volts all the way to distributor. Checked Continuity inside and outside of distributor there are no shorts and voltage flows through the points. My question is does the coil provide the spark or the condenser and should I replace either one? I have disconnected all hot wires and cleaned all contact points with steel brush to ensure good connection. I don't know what to do next any advice greatly appreciated.
