What cap. do I need? Answered
I was looking at this instructable ignition coil and I built it without a capacitor, it worked fine except the coil gets hot after even very short run-times. So he confirmed that I needed a capacitor to stop the overheating. So I added one. I used the kind he told us to use (film) and I tried multiple ones, but none worked. He told us not use the metal can type so I didn't at first, but later I got a really big one and tried it. It was the only one I got to work, but then it exploded, so now I don't know what to do. He hasn't gotten back to me, although it hasn't been very long so I don't accuse him, I would just like to know. The capacitors are storing a charge, its just not running the coil for some reason.
