    1985 Johnson 120 Goes WOT then falls on face

    The brown wires give me 0v, at all times, and are the wires the have 589 Ω. And if those 2 yellow wires are connected to the rectifier, with the key on, they read 12v between them. This suggesting the rectifier is bad? I will redo the tests when then storm passes just to make sure.

    This would be for mine. Don't know if that changes anything.

    The diagram does not seem to match my motor. The wires def. Appeae to be yellow and yellow and white, and I only have 1 power pack. . .

    Ok, so its hard to tell what the actual color of the wires are, but look like orange/white line (O/W) and like a pink or off white with black like (W\B) then there is yellow/white (YW) and yellow (Y) YW touched to Y has 2.1 Ohms O/W touched to W/B has 586 ohms When I attempt to do the peak test...

    Black wire on bolt for power pack is solid, will sand and reconnect.

    I unscrewed the 2 yellow wires (one yellow with white line) and motor did not start, then i reconnected them and now am still left with no spark. That's the 2 wires, one side to stator one side to plastic block tired to rectifier. I removed them at the screw on the block.

    Had a change of plans this morning, will try and get on the water on Sunday morning. What kind if results should I expect when I disconnect the yellow wires? And then where to go from there? Would like get all possible testing done while I have it on the water. Thank you

    Well to look at the coils, the back "gel" filled area was degraded and soft. Not sure of your experience with them, but have also had coils throw intermittent spark on my yamahas, they heat up and start fail. Which would suggest they were wearing out, not flat out failing, as you would say. 36...

    Something else to add that had me questioning the rectifier before, I noticed on 2 or 3 occasions that the tach (new tach- didn't trust the old one as rpm change in tach and sound in motor did not always change together) would drop to 0 for a second and then jump back up. This does not...

    Ok, and what should results be? If it doesn't fall on its face is it the stator or the rectifier?

    1985 Johnson 120 Goes WOT then falls on face

    And your suggesting I disconnect all the wires from the rectifier (5 or so) and then run motor?

    How do you suggest testing rectifier? What do you mean i have no slow?

    When we mimic this at the house on muffs, the plugs always seem wet. That's why I replaced plugs, wires, and coils. Along with why I have a power pack om the way. Not to mention a lot of those are tune up/ ware parts that haven't been changed in years. So If I don't have spark or i have...
