[CA11] ST60 wind, tested voltage
I have a ST60 wind instrument that is not working, I'm not sure if it is the wind vane or the instrument (gauge). It will not show direction of wind and will not linearize.
I jumped out the instrument and but left the R wire which has 8 volts going to mast top, from Blue to shield I have 7.62 volts and on Green I have 7.40 volts. I understand the voltage should be between 2 and 6 volts.
I'm assuming this test indicates that mast head unit is the problem, since I have correct voltage going up but, out of spec. readings coming down to instrument, is that a correct assumption?
Thank for any help
Jim
