Another sad Aussie coil story!



Original poster: "Mr Gregory Peters by way of Terry Fritz <twftesla-at-qwest-dot-net>" <s371034-at-student.uq.edu.au>

Well, the new SRSG was working quite well, and the coil as making about
7-8 foot worth of sparks. Then the secondary decided to short a few
turns and burn up. Murphy's law had to apply, meaning this happened ONLY
on the side that I could not see from my position (otherwise, power
would have been removed immediately). The coil was running in the dark
outside and the only sign that anything was wrong was the sudden
appearance of large clouds of smoke! I think the coil must have been
overcoupled, as there are burns in several positions up the secondary (I
should have listened to you Paul :)). The damage looks too bad to
repair. Oh well, time to make a new secondary. Believe me, I wasn't this
calm when it happened, that secondary cost lots of money! A word of
advice to others: Never run a new coil by yourself without others
present looking at the parts of the coil you can't see.!
