Did you check the primary and secondary windings in the coil for resistance values. I believe #4 HT to #15 terminal should be around 5-8k, primary side should be less than 1 ohm. BTW, a coil can open under load and test OK with a VOM.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
