Excellent diagnostic work; the thermal images in particular are quite enlightening. I have a question about the condenser ratings that you have given. They may be correct, and from my experience the engine will probably run fine at those values. However, they are about 10 times the value of commercially available units. I have found that most current condensers are in the .20 to .40 microfarad (µF) range (the original Mallory "Trash Cans" were rated at .36µF). That both of the ones you tested are a factor of 10 larger is curious. Are you using the proper scale on the multimeter? This is in no way a criticism of what you have done, but I want to make sure we are talking about the same thing, as in my position I need to know as much about these things as I can.

BTW, the uf symbol is the same as the fancy µF.
