After receiving the new ufrc, and installing, all is well. I decided to open this thing up and see just what it's problem was.

It took some time to get this thing apart to this extent, and in the image above from what is evident you would think water contamination causing some bad connection from corrosion, etc.

A closer view gives you some idea how it's constucted, reminds me of telephone connections, solid copper wire stuffed in the terminals. The upper plate in first image keeps the wires separated while it's sandwiched together.

What's this bluish green stuff? Looks familiar.

Here's the problem, after tracing this through the ufrc, it is in the circuit supplying battery power to the PCM. The connection was at the tips of the sharp points where the wire is corroded away. Many other wires in this thing were the same. Some looked overheated like the one in the foreground of this image.

Another view tells the tale, this wire is being eaten by something, wait a minute, I know, this thing is mounted directly over the battery, now I know why the bluish green stuff looked familiar, battery acid! This thing is getting eaten by battery gases that probably fill the inside of this thing while the battery is charging.

Brilliant place to put it, huh? This thing will be the source of many intermittents, watch them.
