I've been puzzling over the same question as I've been fighting with my
new temp gauge(s). There were suggestions from members of the list that
one of them was for an idiot light, and one was for the gauge. If one
is for an idiot light, it's aptly named because this idiot can't seem to
locate it. While trying to track the wires I ended up getting confusing
signals from the two because I seemed to get continuity between the two
when the upper gauge was connected. Of course the wires disappear into
a harness that emerges some 20 feet away in the helmstation, so it's a
bear to try and track. They look identical except one has a screw
connector and one has a spade connector. I know that they do not feed
the two different gauges now, as I had to replace both gauges to get
them to read the same, although now they both read about 20deg low. I
might have to change the sender(s), but don't know if I need to replace
one or both.
I found these two articles on the Faria site which deals with
troubleshooting temp gauges, which you might have a look at. As for
your particular problem, I'd be looking for a poor connection or broken
wire on the 12v, ground or signal wires, which is breaking the
connection intermittently, and causing it to drop to zero.
