Weird indeed.
If you run a wire between the two in-tank level positions, then does the
light come on full and strong (and not fade over time)? I am guessing yes
from what you said about touching the wires earlier.
If yes then I think problems with the circuit board is eliminated and the
conductivity of the water you're using is in question. You could try
adding some salt.
I'm not sure exactly why off the top of my head (maybe David Beirl has an
opinion?), but I think the fading behavior you see is actually consistent
with a dearth of ions in in water. You can try an experiment with a
voltmeter and a glass of water. Set it to measure resistance and put the
probes in the glass. The resistance rises over time. Take out the probes
and replace them, the resistance is back where it was, but rises again.
I guess another possibility is that there are some conductivity problems at
various wire connections that are making things borderline, and then the
difference between your water conductivity and perfect conductivity is
enough to push it over the edge. So if adding salt fixes the problem, you
might find some connections you can clean so that the salt won't be
required.
