Since it is the board revision and you can see the different quality, specs, etc. of the board level components, I think I would photograph the boards
and differences, take them into something like Photoshop and put big yellow arrows on them showing exactly the different revision numbers, identify
the part differences, etc. and send them to Eaton's engineering department and prove to them that you know there is different revisions and that ALL
your failures keep coming up the same Revision #2 boards and that you want to know what the difference is, and/or you want replacements with later
revisions (not Rev. #2) or you will start contacting other users on the issue. It might push them to get you the boards that work, or acknowledge
there is a common failure point, even if they don't do a recall. They should remove all Revision #2 boards from their inventory.
This isn't on topic, but I had a problem with a mfg. truck that air bags failed on in crashes. My friend worked at a collision repair shop and when
they took apart my truck, they had every step on video and showed the failure of the air bags, which turned out to be a clock-spring in the steering
column that separated by the thousandth's in the collision failing to trigger the air bag. But, the mfg. denied there was a problem. After sending
said video to the mfg and the NHTSA, there was a major recall of a couple different lines to correct the issue.
It sounds to me like you have a mfg. that is in denial as you say and they need to see that the people dealing with these problems are FULLY aware and
have proof in hand. The photos and a nice letter might be the factor to force them to admit a problem, or more likely to magically discover a problem
with the Revision #2 boards and offer replacement cards. Once they are called to task and they know that you know, it becomes a problem for them to
later claim they had no knowledge of it in a court case. Their lawyers would probably advise them to quietly appease any clients with bad boards. Just
a thought. I would probably do something like that. You could go further, putting pics out on the net in forums that their clients are likely
discussing your industry issues at, and maybe there will be some collaborative effort with other clients that are having the same problems as you are
to get their attention. They probably haven't really had anyone call them out with photographs before. From what you say, the board revision does make
value changes in the component level parts. Someone, in their engineering office made those changes. They probably are used to what we always called
'parts changers' going out changing boards and not actual E.T.'s or Engineers analyzing the component level. And, the people you order from or
communicate with may not know there are revised boards. It wouldn't be the first time a big corporation didn't tell the tech support and order people
what was going on in the shop.
