No not for that short time. I would not leave it connected for "a minute" but you should be "flicking" it with your jumper anyhow. LOL current? I've never actually measured a coil current draw....2-5 A I'd guess
I am not getting a "fat" spark anywhere. Where's my error in wiring? Here's a picture of my bench setup and a diagram. Shouldn't the center "coil wire" fire to ground (negative) ?
