Reply To: Caps for John

Well FWIW my experience with Digikey capacitors has not been that good.  In short when installed bare they did not fit on the mag plate well.  I used Digikey part BC2609-ND , Vishay MKP1839-HQ 220 n +-5%, 850V.  I suspect the capacitor failed when running because I had bent the light wire excessively.  Before the motor ran very well but skipped when the wire eventually broke.   Motor is a 1956 Johnson 15 HP.

Had another failure with a 1956 Evinrude 15 HP.  In short I was messing with the motor using starting fluid and got a large backfire.  Bent even the linkage that rotates the mag plate.  The cap was hit by the flywheel and torn away.  I think the points fired when the capacitor was hit.  I assume capacitor had shifted position as the motor had previously run ok.

Maybe someone can suggest an improvement in how I mounted the capacitor?  The motors did run well with these caps.

Here is a photo of the caps installed on the mag plate.   Ignore the 1st attachment.  For some reason I can not edit it out
