Perform the latch up corrections as previously detailed.
Disconnect the sensor wires from the back of the meter.
Reconnect the wind direction wires. If there is still a fault in the wind direction portion, then
the problem is in the wind direction sensor or the installed wire.

Connect a jumper wire (a paper clip will suffice)
between terminals #4 and #5
The instrument should indicate
"0" speed and "WSW" direction. If not,
the fault is in the instrument.
Remove the sensor from the roof and
connect it to the indicator with short
pieces of wire.
Rotate the vane slowly and observe the
lights. If it still does not operate properly,
then the fault is in the sensor. Otherwise
the fault is in the installed wire.
The unit will now perform the self test, all LEDS will light
for about 3 seconds. If you did not have time to check
that all LEDS light, repeat the procedure. This will cause
the self test to start again. If some or all of the LEDS do
not light, then the fault is in the instrument.
