Capacitor on MM

It's been a few years since I have been in a physics class (ok, only like 4, but that is long enough) but I think that should be fine. I am 99% sure the voltage issue wouldn't matter (as long as your cap is rated higher then your source) aka even if the cap is capable of holding 50v, it should only be able to charge as high as the power supply connected to it. As for the uf, I think 3300 is a little overkill (bigger the number, the more capacity it can store), but it should still work again, I don't think there is any drawback to a larger number here (other then more weight).
(disclaimer) As my engineering background is chemical, not electrical, I can honestly say I didn't study that section of physics to heavily so my statement, if it agrees with the other would be good for a consensus, not as fact on its own.

I have a feeling that it will be fine, as long as you drive it David.

Being that you are canadian, and the capcitor is also canadian, you will be fine. If someone who is not canadian (me for instance) would drive the vehicle, there may be a compatibility issue. I only say this as I purchased a few products that were made in mexico (and I am not mexican) and they did not work. I work fine with chinese and taiwanese products, but am not either nationality, so my theory may not hold true?!
