  • Johnson 25HP Rectifier wiring.

    I purchased an aftermarket rectifier to replace blown original on a Johnson 25HP. (J25TESNF)
    Its a four wire rectifier. The original had red plus 3 yellow leads and each of the yellow leads had a different colour code on them in the form of a small coloured stripe.
    Problem is the aftermarket part MES 581778 has no such codes and all the yellow wires appear to be the same. Anyone come across this problem or is it safe to connect any yellow to any other yellow on the engine.
    Thanks for any help as dont want another blown rectifier.

    So, your new one has 3 yellow? Forget the stripes, does not matter.

      Thought that might be the case but thank you for confirming the fact.
      The last think I need is another blown rectifier.
