I need a little help troubleshooting a Yaesu G800DXArotator. The rotator is
about 5 years old and has been working fineso far. It has been used for
turning astack of 6/2/432 yagis – pretty light load. The problem started when I
turned full CCW and it wouldn’t return. My initial suspicion was a limit
switch so Iordered a couple and waited for decent weather to remove the rotator
from thetower. I did that this past weekend.Bench testing seems to exonerate
the limit switches and theassociated diodes. The control unit issending +/- 29
VDC to the rotator eliminating the CU and the cable andconnectors. With the
cable connected tothe rotator I measure 29 VDC when the CCW switch is pushed,
but only 18 VDCwhen the CW switch is pushed. The motorbuzzes a little, but
will not turn with the 18 volts. The suspicious unit is the “filter unit”
between the limitswitches and the motor. The filter “looks”OK, but I have no
idea how to test it. BTW, no sign of water in the bottom of the housing.Has
anyone had experience with this type problem with
aG-800DXA/G-1000DXA/G-2800DXA? Regards,Dick N4RA
