Electrolytics usually have burst membranes intended to prevent them from exploding when they evolve gas and they usually work on low-voltage ones. They often work on high-voltage caps too, but other times you can get a nice bang. Big motor starter capacitors can be fun that way. -- John Hasler jhas...@newsguy.com Elmwood, WI USA
