Can any of you give me any info to help with some basic troubleshooting of the rMS on my rEvo?
I bought it used last summer, but it took until 3 weeks ago to get my training to dive it.
The first 4 or 5 times I fired it up, rMS was working.
Then, I was my training and I had an issue with my HUD not calibrating. I tracked it down to a splitter that was allowing the HUD and the Predator Fischer cable monitor to share an O2 sensor. The Predator controller has its own 3 sensors and does not share any with the HUD or Predator monitor. I tossed the splitter and then the HUD calibrated just fine.
The point is that during that process to track that down, I did have the sensor tray lifted up out of the unit and was messing with the wires to those sensors. That SHOULD not have affected any of the wires to the sensors for the controller or the wires to or from the O2 sensor board (which is also the rMS board).
So, even though I don't think I did anything that would affect the rMS, after that the rMS for the inhale side (which is where the O2 sensors are) was no longer working. I could go into the Predator Scrubber+ screen and view scubber temps and it would show me a full set of temps for the exhale side, but none for the inhale side.
I tried swapping baskets. Still no inhale side.
A buddy brought over his scrubber baskets, which work fine in his unit. In mine, still no inhale side temps.
Tonight, I needed to replace a couple of O2 sensors with new ones anyway, so I had a look at it. I installed 2 new sensors for the controller. I unscrewed and lifted out the O2/rMS board (i.e. took it off the sensor tray). I disconnected the DiveCAN connector so that that O2 board was completely removed from the system. Then I put it all back together.
The controller sees and works fine with the new sensors. But now, not only am I not getting temps from the inhale side, I am also not getting temps from the exhale side.
During the process, I did swap scrubber baskets back and forth between the inhale and exhale sides, but I did not DO anything with the board on the exhale side.
Is it possible that I have a bad temperature probe and it has somehow managed to kill both rMS boards?
Is there some way to test the temperature probes to verify that they are okay?
Any suggestions are welcome! I would really rather not send my whole unit to Ocean Edge and pay them to diagnose it all and potentially tell me it needs new temp probes and new rMS boards. That looks like about a $1200 proposition, just in parts.
I was starting to think I just needed a new O2 board and was preparing myself to go ahead and spend the $300. But, now I am not at all sure that that is what I need or all that I need.
Thanks!!
