<font size="+1"><font face="Comic Sans MS">It's the output from the
magneto stator ignition, so it depends on how hard you pull the
starter cord. When the engine is running (2K + rpm?) it might
be higher than 60 hertz, but it probably don't get that high
with manual start.<br>

<div>At what frequency does it operate? The circuits
below probably assume 60Hz. If you are running at a
much different frequency, the cap value may need to be
adjusted.</div>

Johnson 9.9 outboard on Craigslist. It don't have a
spark. I've run through all the Ohm meter tests and
all seems OK. The manual has tests were you use a
special meter to measure peak voltage from the
stator coils. I figured you could make an adapter
so you could read peak with the DC setting on a
VOM. MY first search on the web gave me this
circuit<br>
<br>
On searching a little more a guy suggested a mod
which makes sense. He added a resister to limit
current.<br>
<br>
So does this look like it will work? It don't have
to give a real accurate reading, the tolerances are
large.<br>
