Ha ha, yeah, I have plenty of duh moments; but this isn’t one of them…..The Mercotronic was set on 500 and the little ES (Mercury) DVA meter was set on its max of 400. Interestingly, this same neighbor also has a 1989 70 Johnson. Just this past Sunday, he couldn’t start it after sitting all winter. NO spark. That was a charge coil, failed open and my meters worked perfectly to find that problem quickly. He had a spare engine, we robbed the stator off it and the 70 is now running fine. I even tested the output of the second stator, when I put it on and it was around 280ish, just what I would have expected.
I don’t know for a fact, what the charge coil output is supposed to be on this 150 model….and since the motor was actually running on the stbd. bank, my output was not cranking voltage but RUNNING voltage….However, I have still never seen that much on anybody’s brand of outboard.
I do know I could swap packs but my concern is that the charge coil’s high output might have ruined the non-firing pack…..and I don’t want to keep messing around until I smoke the other one…..
I seem to get more than my share of weird problems. I can’t imagine how the two separate coils could somehow have shorted so that they are working in phase to produce double the peak voltage they are supposed too…???? I wish I had another stator laying around to try; but they are not cheap.
Long live American manufacturing!
