1) 10 Position Connector at the 302 - Everyone always suspects
connectors so lets look at this first. Generally speaking this type
of connector (what is it's proper name?) is a pretty robust animal.
As long as the original wiring connections were properly made in the
first place then I doubt that it would give up the ghost.

I know it as a Weidmuller BL3.5/10. (See http://docs-europe.electrocompo
nents.com/webdocs/0029/0900766b8002900d.pdf)

Does the voltage reading on the 302 change (or the unit power off) if
you hold the case and connector of the 302 steady and wiggling the
wires leading into it? The connections are made by tightening small
screws. Unscrew each one and check each connection and wire. There
are many strands to each wire - are they all in their proper place? I
strongly suggest that the strands be twisted together and then
soldering ("tinned") into a single "wire". That gives something solid
for the screw to bite into.

Not a good idea in my opinion. Once you tin the ends of a flexible cable
into a single wire, it is no longer flexible and you provide a fulcrum
which can cause a break in time.

A crimp terminal pin is a better idea where the insulation is held.
