Found a pic of the capacitor. Looks to be the electrolytic type if I'm not mistaken. Scroll down the page to see it: http://www.weather-watch.com/smf/index. ... 90.30.html
Looking at the info in your link, makes the likely circuit design clearer. It's not an ordinary capacitor, it's a "super capacitor", one designed to store electrons like a rechargeable battery. It's also very, very likely you have the capacitance value wrong. It's likely 10 Farads not 10 micro Farads. There is a big, big difference, one million in fact. You need to verify the value. Also measure the length and diameter of the capacitor. I should be able to find a suitable replacement, perhaps even an upgrade.
