Ignition Condenser (Capacitor) Values

I tried an internet search for this and didn’t find an answer. Does anyone know the values/specs of a good ignition condenser? I’ve seen comments saying anywhere from 0.01uF to 0.6uF. That’s a HUGE range and manufacturing tolerances are much tighter than that, typically ~20%. My application is the S-code, but I’d be interested in the values for the other engines, too, if they differ.

I’m replacing the points and know a lot of people automatically replace the condenser too, but the new ones are supposed to be crap compared to the old. I don’t see a need to replace an old part that’s good with a new part that’s more likely to go bad sooner. I did measure mine and it’s 0.20uF, so I know what it is, but don’t know what it’s supposed to be.

Thank you for any replies!

Factory Service Manual for 66 Mustang has the spec for ignition capacitor as 0.21 to 0.25 uF. I can’t imagine it would be different from year to year…

Thank you, Midlife. Looks like I should order one in then.

Anything under .5 mfd will be fine. All the condenser does is keep the points from burning. A failed condenser will show very low DC resistance.
