Jeremy,
With a piece of high voltage wire (20 KV Test wire of Neon HV Wire) see
if you caan draw equally long hot arcs from the transfomer case (center
tap) to each HV output, one at a time. Oftentimes, only one of the two
windings will be defective - 2 properly connected 1/2 good neons can be
made to "look" like 1 good one if you're desperate.
Safe coilin' to you!
