peak voltage adapter.

One comment:
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.

Subject: peak voltage adapter.

I bought a  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

On searching a little more a guy suggested a mod which makes sense.  He added a resister to limit current.

So does this look like it will work?  It don't have to give a real accurate reading, the  tolerances are large.
