squonk 43,775 #2 Posted August 3, 2022 Yes. The coil is only powered briefly per revolution. 2 Share this post Link to post Share on other sites

You'll probably also kill your battery if left that way for a long period. They'll only get hot if the points are closed. If you're lucky enough to stop with them OPEN, the coil won't get hot since there's no current flowing through it. 1 Share this post Link to post Share on other sites
41chevy 74 #5 Posted August 3, 2022 Thank you, I’d just finish rewiring everything and accidentally forgot to turn the key. 2 Share this post Link to post Share on other sites
