I completely agree with you on this tactic. I started my working life as a bench technician with Systron Donner testing new and customer instruments. There would always be that odd "dog" unit that you couldn't fix. Hey ho, put on one side for a couple of days and get on with the others. 99 times out of a 100 when you came back to it the fault was literally staring you in the face. Happy days!

Hi It's amazing how often the key element in any troubleshooting procedure is - stop, put everything down, take a deep breath, get a cup of coffee, think about it for a while. I've seen people go for weeks without executing this very important step.

Bill, Yes, +5v.... but I was doing it incorrectly (bad hookup wire on both units). I haven't checked the second "bad" unit, but it will probably work now too. Sometimes I have to hit the "send" button before I find my errors.
