DougWhen working an RV, it is so important to make a proper capacitor tuning box complete with a good strong switch for each and every capacitor. The switches should be the kind that make a good positive connection, not expensive, but not you silent wall switch either.Lately, I have been using Chinese made 30 amp 12 volt dc toggle switches. They are not rated for 120/240 volts, but take one apart and see how it works.I think it is some kind of trade sanction, but they work for me, and do a good job, connecting, and disconnecting with nice brass contacts, and springs, separated with phenolic plastic.$ 2.00 each at Princess Automotive during their lost leader sales in Canada. Just rated for 12 volts you know, nudge, nudge, wink, wink.My caps, apart from my home made knife breaker switches, which have never failed, are 600 volt oil filled, that I have purchased on line, haunted surplus places dusty back shelves, and collected like the awful hoarder that I am, in the low value mf ranges, as these were harder to get for me. It is nice to have 1 and 2 mf oil filled caps, complete with the each and every one having its own switch. I place them in Pelican type waterproof tool boxes, with proper inline plugs and sockets coming out of the boxes, so the whole thing is light and portable as it can be. Duh! Label each switch value! I learned.If you dabble in RV or any free energy, you need this tool, an adjustable capacitor of good power and range.Cheers Warren

Hi Werner
OK sounds good - just get the motor going first with start cap to start it, and then much smaller uf run cap replacing the start cap when it gets up to speed.... and then play with run cap size some more to lower draw as low as possible,....then after that, try the series transformer experiment...
Do not switch in the big uf start cap while the motor runs with the small uf run cap connected at sinewave speed!!
This will cause extreme magnetic braking to rotor and the motor can lurch off bench or even possibly explode if going high rpms...
