I have the 2SD1071s and the correct diode 1N6303s in my 1965 33hp with tiller steering I picked up last season. I have to put a new impeller in it and check to make sure carb is clean but I fired it up yesterday 2 times and rev’d it up a bit modules stayed alive and it sounded good. It has the original purple colored OMC coils in it and I thought it would be a good candidate to test these particular modules in since it has its original coils and it is a low hour even the magneto area was clean as a whistle.
What I do like about these coils is everything wires up as normal the way I am building my modules so I don’t have to reverse the small wires to the coil by extending the ground small wire a bit so it can go to the screw on points where the positive wire normally goes I then ground it but the purple coils don’t require that see pic. The brown and green wire are wrapped together and soldered to the other side of the diode opposite of the grounded side and go to leg E of 2SD1071
I am going to refrain from using silicone on this modules so I can inspect them after like 20 hours of run time.
