Ignition coils have different primary winding resistance values. Hondas with points and condensers usually measure out around 4-5 ohms on the small wires. If you put in 1-3 ohm coils from a bike that has an electronic ignition, then the whole thing will draw too much current.
Honda coils seldom fail. Be sure that the points are clean, gapped at .014" and set to open at the F and LF marks. If the points are arcing heavily when they open and close, either the condenser for that point set has failed or the wires are loose where they all connect.
