[QUOTE="Magnetoman, post: 39640, member: 2806"] This is a "fix" that is sometimes mentioned, and I know you said you've done it, but it doesn't work for quite fundamental electrical reasons. A failing condenser is analogous to a leaky dam, and attaching a good capacitor in parallel to a bad one is analogous to trying to fix the leak by building a solid dam at the top of the hill overlooking the creek -- it doesn't matter how good that additional dam is, it can't stop the water leaking through the original dam. It's not just that I can cite the fundamental reason this "fix" won't work. I've done a full set of experiments placing a good capacitor in parallel with Lucas condensers in various stages of failure, and the measurements confirm that it does not work. I've done this with an impedance bridge, to collect quantitative data, as well as with one of my magneto testers, where I can watch the increased sparking across the points. [/QUOTE]
