Hi Chris,

Do you have a schematic of your setup? If not, we could draw one up I suppose. It would be good to get everything labeled out for ease of discussion.

Any particulars regarding the scope would be good too - like timebase setting, AC or DC coupling, X1 or X10 etc.

I like the capacitance switch - very handy. At most of the places I've worked in my younger years we had resistor, capacitor and inductor 'decade boxes' that made things easy.

If Pin3 goes to the relay coil, isn't that the bottom trace in both pics?

So the top trace is . . . the output with or without the diode?

It would be interesting to see the primary vs. the secondary.

Cheers!
