    First... the 1st 3 3 responders could be slapped! the only reason to be so rude and unfavourable is to make oneself sense important at somebody else's cost. sure, you made some blunders and you already be attentive to that. So... once you get sparks and warmth it ability something is shorted. In different words, you have have been given 2 or extra products of metallic touching one yet another that should not be touching. perchance some solder have been given into places this is going to no longer be or maybe the unique capability surge melted insulation and allowed the touching. once you're particular you basically see sparks around the capacitor you basically replaced, my first wager could be solder overlap or perchance you place the capacitor leads contained in the incorrect holes. As responder 4 stated, look for burned or melted insulation (varnish in coils, rubber/plastic on wires) and look for wires, solder or different bits and products that should not be touching. additionally, ensure which you place the hot capacitor wires of their desirable places. issues like capacitors, transistors, diodes, etc. have polarities (variety of like a front and decrease back) and can be orientated good. look for the advantageous lead mark (or learn the previous one and tournament the hot one to it) and confirm it is going contained in the advantageous place, which ability the comparable hollow the previous one replaced into in. As for the guy who mentioned capability factors are deadly...it somewhat is purely actual in the event that they're plugged in or...and that's amazingly important!... if there's a capacitor that continues to be keeping a cost sufficiently vast to harm you. Capacitors are electric powered storage gadgets and could, like a battery, carry a cost for a protracted time (even whilst the capability is grew to become off) till they're discharged. are not getting your physique areas contained in the way of that discharge. Now, as responder 4 mentioned, get your magnifying glass and learn those areas and connections.
