like this? I would imagine that you could use an inductive pickup
similar to the type found on a timing light placed around the
secondary lead. I could wind a coil if need be. Does anyone know if
this would be a viable procedure, and if so the details of the coil?
Thanks, Lenny


I would have though the usual fault was interlayer discharge within
the HV windings. You can do a simple comparative test with just a neon
and 100 Meg of resistance dropper. Strongest orange discharge glow ok
, poor or non existant glow , bad




I would think that oil would be an insulator.
It's probably defective coil construction or problem with the plastic
potting,like cracks admitting moisture.
Maybe aftermarket coils would last longer.



The easiest thing to do is swap the coils and see if the problem moves
with the coil. I agree with Jim, it is most likely a potting problem and
an aftermarket coil will resolve it.
