    dyna coils

    Howdy,
    Are there any external markings on dyna coils to tell me if they will work on my 11s
    There is a huge swap meet in Denver this weekend and I located three sets of the green twin plug coils.How do I test them and
    What would be the ohm values primary and secondary be with out wires?
    Thanks in advance

    Be careful they may be the MikesXS faulty green coils, I think the Dyna says Dyna on them. They should be about 3Ω between the small wires.

      Howdy RD- The coils say Dyna on the side, and on-top in white will state the impedance (DC-I's are 3 ohm). Bring a DMM with u and measure across the screws (3-3.3 ohms), and secondary resistance between the two plugs should be 13-15. K ohms. We have those swap meets in Michigan a lot. Never been, but the guys I've talked to said it's mostly dealers selling over-priced parts instead of your backyard guy selling off basement parts.

        Dyna colour code their coils. Green coils are always 3 ohm...

          Unless ur really an eager buyer and grab the green ones and did not notice they were single output coils versus dual, lol.
