Bart, there was one time that I ran the coil without the ground
connection. I did this to show another person that there is no
electricity connected to the secondary coil through the ground wire,
and that the energy transfer takes place through electromagnetic
induction. It's likely this is when the problem started.. I will try
without the inside loops and see if that prevents the problem. The
burn mark sanded off easy enough. I have looked through Home Depot
for PVC end caps and have yet to find them. Still trying to find a
thicker piece of plastic that can be cut into two end caps. The
previous end cap, made with the plant pot water catch plate, was not
thick enough.
