hi y'all,
Yesterday I was trying to diagnose a dead sink water pump, and in the
process happened to discover that the water in my Westy holding tank always
has a voltage of +0.3 volts, even when all systems are
off.  Ummmmm!!!!!????  Is this normal?  I am wondering if the water level
LED "meter" thingy is malfunctioning.  No schematic handy.  The meter does
work fine and turning it on makes the voltage of the water go up to
+1.5volts.  This is an '84 Westy.

In the interest of science if anybody could stick a multimeter probe in
their water tank and see if there's voltage when everything's off, I'd be
grateful.

thanks,
