[RE-wrenches] Trimetric with Outback

[Dan Fink]

Bill -- I have "cooperatively attached" 2 different shunt monitoring
devices to the same main (DC net -) shunt with no issues, for similar
reasons (kitchen where client wanted a simple display is too far from
shunts and Mate). The phrase is from the Midnite Whizbang Jr. manual, they
supply a couple aluminum spacers for the other company's shunt sense wires
so they don't short the WBJ board (the WBJ electronics mount on the shunt).

As long as the ring terminals for the Trimetric sense wires can still lay
flat while stacked on the FNDC sense ring terminals, you should be fine. I
don't see why you couldn't use conductive spacers if the ring terminal
barrels interfere with each other and won't lay flat. In my client's case,
a second Mate for the kitchen was over twice the cost of a Trimetric
without shunt, AND he can read the Trimetric from across the room because
of the good ol' LEDs, not so with a Mate 3s.
