Hello John

I have two Davis systems. The first is the Weather monitor 2 that I have had
since 1998 - served me well and I use this for recording grass minimum
temperatures.

In 2005 I upgraded to a wireless Vantage pro 2 bought from Prodata and this
is my main system which has also given me good service.

However, I was using the weather monitor 2 as a check on my rainfall
readings against the VP2, but the rainfall readings have just stopped this
month - still gives 0.0 on the readout. Also this has always had a tendency
to under-read.

What is the obvious cause of failure on the rainfall sensor on the weather
monitor 2? My cables do not join anywhere outdoors

a.. I have checked and the tipping mechanism seems fine.
b.. After over 10 years would the most likely fault be the reed switch?
c.. What should I be looking for?
d.. What advice would you give me bearing in mind the Weather monitor 2
is not my main operational system.
e..
f..
g.. Any other suggestions welcomed

Almost certainly the reed switch Rob.
RS Part No. 229-3670

These are the ones I have used before, I think the part number is still
correct, anyone can confirm?
