Gotta love creative thinking. There is a market for transistor testers, which are an order of magnitude more complex. This could be accomplished, even with the variance in terminal layout and design. I was a little disappointed in the way Dan Sulllivan's idea of the LoadPro crashed and burned. In that case I think it was because it was marketed in such a way they didn't emphasize the basic thinking we all use when diagnosing circuits. He didn't show how simple the design was, perhaps because he didn't want anybody to build their own. In the end, the black box approach he encouraged isn't compatible with the kind of diagnostic thinking we need to work out problems. The thing I'd really want when diagnosing a relay is to be sure the power side is not confused with the signal side, so that the chance of frying something by jumping power to the wrong side is reduced to zero.
