8ntruck 6,875 #2 Posted August 31, 2023 Kind of sounds like a coil problem to me. Have you checked the resistance across the primary on the coil? Maybe check for continuity from the secondary to the case of the coil - there should not be any there. Good luck. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,921 #3 Posted September 1, 2023 If you have points the wire from the coil to the points should have power when the points are open and 0 volts when the points are closed. If this is not happening clean the point contacts. They are not making an electrical connection when closed. 2 Share this post Link to post Share on other sites
pacer 3,160 #4 Posted September 1, 2023 @gwest_ca probably has it -- points can get a ...glaze? on them or just simply get dirty. Run some fine grit paper through them..... Share this post Link to post Share on other sites
