      I need a little help in understanding The coil operation and testing procedure for the early coils that are used on two cylinder motors.
      Do both these sparkplug wires spark together ?
      In testing the secondary circuit do I attach my ohmmeter on the two sparkplug connectors and hope for continuity ?
      This coil is off an 30’s Evinrude Speeditwin.
      Thank you for your help

          1st picture is Speedifour, one coil ok, other shows no continuity between sparkplug leads, I removed both coils and removed the sparkplug leads to eliminate bad leads.
          Second picture is a coil from a 29 Fastwin also tests bad secondary.
          Any suggestions for replacements ?

              Thanks, Tubs.

              What about those surplus coils being sold on the internet? They are two terminal secondary. Maybe I can adapt them.
              I appreciate your help and will let you know what I learn.

                I think the surplus coils you mention would be perfect. Let us know how you make out.

                      In the process of adopting the surplus coils (Big Rich) to my Speedifour laminations. I think I will leave the lamination bar in the surplus coil and fasten to my Speedifour lamination. I’ll keep ypu informed.
