Hmm, I said that you could inspect the brushes of the spindle
motor. Get an AM radio and listen to the interference (if it
is audible). As to why Allison doesn't seem to have this problem,
she probably does not have the RFI source you have in the RX02
:-) Perhaps your RX02 is only missing a simple wire to connect
"something" to the frame of the RX02 to ground whatever ...

You have to be kidding me. I have that
arrangement and it's solid.
The
RX02
bottom is well shielded as it the top of the RL02 logic.
Not only am I not kidding, but I can PROVE that RFI/EMI is
the problem.
I took off the side panel of the H960 cabinet so I could
access the RX02 and
RL02 from the side, without disturbing any cables whatsoever.
I slid a metal sheet inbetween the RX02 and RL02, both of
which were fully retracted inside the cabinet.
I powered up everything and then hit load on the RL02. It
loaded fine with no fault.
From the side, I could pull the metal sheet
between the two
out towards
the
side. After sliding it out a few inches
the ready light would
start flashing... the further I pulled it out the faster the
RL02 ready light would flash. If I pulled it out all the way,
the RL02 would fault. Problem proven :)
I'm not saying that ANY RL02/RX02 combo will have this issue,
but mine clearly does. And it isn't cables. I do have to
disagree with you on one point, the top of the RL02 logic
sure doesn't appear well shielded to me.
With regards to the RX02 - the left drive works fine, the
right drive has never worked. I will try Tony's suggestion
tomorrow and see if that confirms the diagnosis. But when I
can move a metal sheet between the drives and cause/fix the
problem, I'm pretty sure I know what is causing it. So if
Alison has this same set up and it's "solid" for her, why is
it not for me?
