can't seem to isolate the problem. It seems where ever the

it influences the whole board. Is there a technique or

it needs the whole setup to run and it is far away in a

place. Any helpful ideas out there for me. Thanks

What's wrong with the boards? A DMM with a diode check
function is
probably the best tool for the job, just test all the
transistors,
they're the most likely fault in a machine like that which
drives
motors or lmps.
