: Anyone have any theories on why 4 new ignition coils have failed within last 6 months on a '64 jd 1010 RUS?
Ignition coils can fail if the polarity is wrong. The 1010 should be a 12volt positive ground (unless it has been converted). In either case the terminal connected to the distributor should be the same polarity as the battery ground. Good luck.
