condensors for Scintilla mags

What is the current best source for kg-7 bendix magneto condensors?

I don’t know if they are still available from Prefered Parts, but I still have some new ones in my shop. They are BE625- 10-79188-218578-55 (I have two) and 10-79188-219578-55 ( I have two of those also) I would like to keep 2 of the four for my restored and running KG7.

thanks for the generous offer, but before I take two of these valuable parts, let me continue a while longer to see if any more sources are found. I have a number of KF and KG Mercs and I would like to just replace condensors in all of them if I can.

if you know the uf value of the parts to replace you could install a modern capacitor … probably for pennies

see excellent articles by W.Mohat on capacitors in the last Outboarder edition or…. see condenser articles 1-2-3-4 at his link

.22uf is an all time favorite with some a bit bigger on older engines

update: by the looks of seakaye12’s above post that condenser seems… not very old after all

They can be made by using the proper value capacitor and installing into the current housing.

Give me a price and address of where to send the money. A bird in the hand is worht two in the bush, like thay say.

these are .22uf 630V … not 850v but should work if you stuff them in an old capacitor can (weld one end on the casing via a 1/16 hole in the bottom (see w.Mohat technique)

seal it up with epoxy

Have these caps been tested for durability? Such as running them for a few hours and then comparing their uF reading to their original reading before installing them? Just asking because all caps are not created equally and even though they have the same uF rating, some can’t handle the torture given out by magneto systems.

[crosbyman]

nope.. not tested yet planning to try a few next summer .I know mr. Mohat hinges more on 850V caps based on all the testing he did. Obviously 850 is better than 630

Ceramics seem a better option but the yellow ones (with 850v) seem to do good when stuffed in the tall cans

These 630v ones can be fitted in the small cans . They test 100 % good on the capacitor test box (mdl#1) I built is winter .

So…. the 630 v ones ” seem ” well capable of tackling the 250-300v oscillations as shown on the scope shots in the Outboarder’s latest issued but I agree… real life testing is the way to go. .

I am just going on the basis that if a $2 full wave rectifier rated 50amps will do the job just as well of a $50 OEM 15 amp rectifier modern capacitor design and material may very well do just as good work as a 1950’s capacitor design for pennies instead of 10-15$ a piece.

if anyone has had bad experience with capacitor rebuilds using similar 600+volt caps … please let us know 🙂

I don’t like rowing back to shore anyway !
