    Default mounting a supermag transformer

    I have seem to have found a diffrence in opinions. in the directions from mallory it says to mount the transformer with the high tension lead pointing down to keep it submerged in oil and keep it cool. on fuel injections enterprises website (they now own the supermag and sprintmag line of magnetos) it says the best way to mount the transformer is with the terminals up and the high tension lead out the side. second best is with the high tension lead pointing down. and do not ever mount it with the high tension lead pointing up... So does someone have and experiance with this matter that could shed some light on the situation? Thanks dj

    High tension lead either one the LOW side, or down, never up!!
    If FIE says side, then that's probably how I would do it. I have heard a lot of people do, I always faced the high tension down per Mallory's recommendation.
    I NOW believe the coil is more prone to internally breaking loose if the high tension terminal Is facing down. Not sure there is a benefit to the heat generation/submerged in oil from it being on the side. But I think the coil may be slightly well suited to the pounding of a boat with it on the side.

    Part of the confusion comes from the Voltmaster battery type coil that looks similar was always high tension lead UP, or on the side. But the primary terminals on those were on the same side as the high tension lead.

    Nope, just change the gap. .018-.020 should be fine.
