[amsat-bb] Re: Yaesu G5500 rotor trouble.

[w4upd]

I tried once, but the last reply never came through AMSAT-BB yet. So 
I'll answer yours directly which also answered a previous one on getting 
the parts. I believe your G5500 uses the same elevation (G500b) as my 
G5400 late model. Also it probably has limit switches in the rotator 
which will prevent the down from working until it went up a bit. Mine 
still has a bad motor (actually the armature due to my own fault). As 
long as it draws current and the lamps dim on the UP selection, the 
motor itself is probably still good.

********* RESEND  ********

I find this hard to believe unless its related to the G5500. I just got 
done ordering stuff from Yaesu for my G5400/G500b elevation rotator. 
Unfortunately, the IPB I had with my rotor was for the G500a and the 
parts were wrong and I had to send them back. They did give me credit 
for the returned parts as well. I have a bad motor and they one they 
sent was for the G500a and was $85.00 However, its size kept it from 
being close to being able to be used. When I checked the  G500b IPB and 
gave them  the part number, it was  $207.17!!! So I said forget it. I'd 
figure a way to fix it.

The cap you can get anywhere if that is all that is wrong. Mine had over 
a pint of water and as such rusted and dried and packed the grease 
keeping the motor from working. I suspect you have little choice but to 
take it apart and confirm the problem. Again, unless it is due to being 
a G5500, I had no problems getting parts from Yaesu as recently as last 
month.
