(OP)
Does anyone know the correct pin config. for the transistor, PN2222, My specsheet has two conflicting configs.
Also is there a way to test cbe on this part with a simple volt meter.
Thanks,

The other thing you can look at with a voltmeter is the leakage current and breakdown voltage across the two junctions. Standard vertical transistors use a degenerately doped emitter, which usually means that the emitter base junction will have higher leakage as well as a lower reverse breakdown voltage. The collector-base junction is usually lightly doped on both sides, thereby resulting in lower leakage currents as well as higher breakdown voltages.

actually i think Sencore (among others) makes a low cost curve tracer that would help if you're trying to check reverse breakdown voltage and leakage current.
in the short term, look at the manufacturer's data sheet and trust it; once you've confirmed where the base pin is.
