Or you could have just linked to that thread directly, mentioning that
the result being looked for is off-screen when you open the page. I
reckon a "Let Me Google That For You" reponse smacks of condescension
and is often totally unhelpful. Which is why I'll always link directly
to a solution, if I find or know of one. There's also no guarantee that
a Google search via
lmgtfy.com will come up with the same answer in
different countries.
The answer seems to be 240 ohms when full, and 30 when empty according
to that source, and it would have been almost as easy for you have just
typed that, with a URL for the whole thread.
Now, if I could figure out how to get the bingo light on mine working
again... It's never worked since I had a new tank fitted a while ago,
hopefully it's just a loose wire somewhere.
