Thanks Ed,

Someone had bypassed the open coil in the shadowmeter years ago. They had used an 1100 ohm resistor. I am going to assume that with your help and Rons plus the resistor in the set that I will need to shoot for the 1100 ohm range. I did study the wire I pulled off the coil again under a lighted magnifying glass and it now appears to be smaller than 40 gauge. The smallest I have is 44 gauge. I will try it tomorrow evening and see what measurement I end up with.

Thnaks guys!!
Dave
