It's the fan. No doubt about it, it's the fan in the back of the RX02
causing the RL02 to fault.
I disconnected the fan and the RL02 no longer faults upon spinup. The moment
I put the molex back on the fan of the RX02 - the RL02 immediately faults.
I decided to take a closer look at this fan in the back of the RX02, so I
took out the 4 screws and pulled off the plastic "wedge shaped" housing. The
fan in there is one of those older odd-looking ones. Not sure how to
describe it. Instead of your "normal" muffin fan where the windings are hard
to see and they are around the hub... this is the kind where the fan hub
sits on one side of a large rectangular hunk of iron? Steel? I dunno... big
chunk of heavy metal :)
Betcha if I replace that fan with the more normal kind I don't have such a
problem. The current fan isn't noisy, works good... but I'm betting the huge
coil on it is a problem.
