Howdy, TowerTalkians --
I ran into a problem that's got me stumped. I've got a Yaesu G-800
rotator that doesn't seem to work. It was not tested prior to installation on
the
tower but I haven't ever had any infant mortality problems with Yaesus so maybe
it's something on our end.
I think I remember that Yaesu rotators changed voltage systems recently -
they went from ac to dc or vice versa - I don't remember which, but the
result is that instead of using 6 wires, now they only use 4. Which is fine
except
they don't tell you that in the instruction manual so you wind up soldering 4
extra wires (2 on each end) that aren't needed. And they're not the easiest
buggers to work with in the first place. :-(
Anyway, we got the 4 wires hooked up and it doesn't work - no rotation,
no indication, etc. We've got power and had to replace the little internal 3A
fuse but as Mark would say, no worky worky. We couldn't find any pin-out
measurements like you find with Hy-Gain rotors so we couldn't do any
measurements.
Can anyone give us any simple measurements/tests we can do? We haven't run a
cable continuity check but I haven't had that sort of problem before but I'm
not
ruling anything out.
Any help appreciated.
Cheers,
Steve K7LXC
