Well, if I were to take a guess at it, I'd first make sure that neither
lead had any sort of continuity to ground or any other power or signal
lead. If it's an EL panel, there's basically no resistive characteristic
to it; it's purely capacitive. If a few tests bear that out (curve
tracer?), I'd go ahead and try applying a moderate (~90 v) AC voltage to
it ballasted through about a megohm and see if anything lights up.
