My weather station has been fully functional for many years, but the
wind direction and velocity has stopped working. I suspect one or more
of the IR diodes and/or the photo transistors have failed. I have been
unable to locate replacement parts or to cross-reference the original
part numbers.
The diodes are TIL-32 and the transistors are TIL-78.
I would appreciate any information on where I might find these parts or
where I might cross- reference them to an available substitute.
Thanks in advance to anyone who responds to this request.


Joe -

There are active Heath WX station groups on the Internet.
This is a common part failure - IF you have had a nearby lightning strike -
not necessarily direct (surge alone).

The ID-5001 WX station is actually still made and supported by Forecast
