TurboTom:
Congratulations -- this is great news. Obviously, the "advanced" diagnostic capabilities introduced with signature analysis had their pitfalls: The neccessisty to be able to disconnect the data bus by a jumper block provides a new point of failure / contact problems which apparently caused the majority of the observed problems. Well done spotting that!

You may consider replacing the individual jumpers (which often only provide a single contact surface) with a female 1/10" 8x2 header with the neighboring contact pairs bent over and soldered short. From my experience, these provide much more reliable continuity.

 Thanks TurboTom!

I know right? It's weird that they opted to go with such an assembly for that obviously important link. Only thing I can figure, is that if you really know what you're doing in this circuit, you could remove specific jumpers in the stack to aid in isolating a problem. Who knows? At any rate, I think the connector has been restored to at least as good as it was out of the box.

I'll be starting the re-assembly process soon, and I'll post up with a final sound off on this thread when I get 'er back together. Meanwhile, see the attached screen shots.

Outstanding - The great thing about getting this working, apart from the feeling of getting it working, is that you now have a signature analyzer you can use on other gear  ;D

Congrats on seeing it through.

You're right Tony_G,
Much satisfaction, much future utility.

Always appreciate your contributions! :-+

One final post up with this thing hopefully. I feel like I should outline a couple key points to finish up, that should show up on a Google search if some other poor fool is working on one of these. :)

NP - Always happy to offer whatever, even minimal, help I can.

You should do a post on how to use the 308 to read a signature - Just to flex those signature analysis muscles...
