ID-1290 Weather Station

[John Campbell]

I think you will find you will find that the problem is being caused by a
shorted reed switch. Measure across each switch while slowly rotating the
wind direction magnet, and you should be able to tell which switches are
opening and closing properly. I also have an ID-1290 and this is a common
problem. The biggest problem nowadays would be to find a source for the reed
switches. Anybody else out there have any ideas??
                                Thanks.......John   <w8jnc>
