[amsat-bb] AlfaSpid issue

[kb2mjeff at att.net]

Here I go answering my own questions. I think I found part  of my problem. 
The buttons don't
line up in the case very well and caused the rotor to hung up turning in one 
direction. That was problem number two, I fixed problem number one the bad 
relay that started all of this.To fix this temporality  I have the board out 
of the case to test and what is now  happening is that I still can't turn 
CCW. All buttons work ok except for the CCW  button. I tried a reset 
thinking that I'm over some set location in the firmware that I cant go CCW, 
but the reset doesn't work. I replaced all 4 relays. With the rotor 
completely disconnected I can get a relay click for every rotational control 
button except CCW, it has to be a glitch in the firmware I can't clear, as I 
replaced all four relays.  And no I really don't want to spend the $900 for 
the green heron controller. Any other ideas?
Thanks for your help...

I’m back at my winter home in Florida and decided today, to work on my 
AlfaSpid rotor control box issue. I replaced two relays to fix the Elevation 
issue but in testing it before I replaced the other two relays I’m now 
having a problem with the azimuth that’s been working 100% until this point. 
When I turn on the rotor control the elevation now seems to work ok, but now 
the azimuth immediately goes into a clockwise rotation. No matter what I do 
to the controller, upon startup it starts turning CW, only way to stop is to 
power it down The azimuth was working fine this morning when a worked a 
couple of sat passes. Anyone have any ideas? Does anyone know where I can 
send this to have it fixed? I have no schematic, or even simple instructions 
on how to reset, etc.
