Re: Capacitance Meter

Mumbles,
You took the thoughts out of my head!! Magnetos run very high voltage thru the caps & to load bank not static test is the only accurate way to test for any voltage leakage. It’s like testing a tire sitting stopped in comparison to load testing at full load & speed rating. A mercotronic or Stevens load tests the cap.
At MCM electronics I bought a cap & resistance meter for 40 bucks, non load testing . Make sure the cap is suited for the high voltage encountered with magneto use or it will fail in short order as well.
You can buy many coil & core type caps from automotive use & measure cap mfd rating & use a match like Garry posted a few posts back is one way but then again if it is new old stock may already have leakage from the age of the shelf still new in the box. The high voltage magneto type caps are expensive to manufacture & such a small market such as R.F. transmisson
Look under Vishay brand MKP18394884 HQ for good magneto metalised caps for replacements or specs for dielectric values to rate. Went a little over with the specs, sorry it’s hard to explain half an reply.
