Are you sure you're in tune?  Make sure all your components are good.  
Make sure your cap is good, make sure your xfmr is good, and make sure 
your wireing is good.  I'm assuming you mean 10KV not 10 KVA.  It should 
cross a gap of about 1/4 of an inch, so make sure you're gap isn't to 
wide.  I don't recall ever seeing a diagram w/ the cap grounded at one 
end.  You're primary capacitance may be to low to allow you're coil to 
be tuned.
