Put two extra-bright LEDs wired in parallel, one LED reversed
from the other, in series with the output of the frequency
generator. Connect the frequency generator, through the LEDs,
into the base of the Tesla secondary.

Dial around on the frequency generator. When both LEDs light, the
frequency generator output frequency is matched to the secondary
coil resonate frequency.
