We have 3 PM1s, one on each model B, two have issues. One does not have fully functional buttons. I am wary of disassembling it, but am wondering if the connection is just dirty or something. Another has a very dark screen, but still displays an accurate pace.
We have 3 PM2s, one on each model C. One is missing the pickup (I think that's the right term), that wires into the PM from the flywheel. Another is completely shattered (need to buy a new one
). The third is very inaccurate - sometimes it displays the correct pace, sometimes it's showing one hundred something SPM and completely incorrect paces. All of the PM3s work fine. Two on D's and one on a C.
If you have any suggestions about how to fix the problems I have listed, please let me know. If you have extra monitors (or ergs) laying around - let me know even faster! When you have fifty kids needing to learn to row or increase fitness in the offseason, it's hard to cycle them all through on the ergs. And who knows what they're really doing if we send them running. Keep them on the pain machine I say
You can take the IC board and clean it is distilled water and then dry it in something like a vegetable dehyrator. You can do that with the whole thing for that matter. But you need to make sure that immediately after the rinse you put the thing in the dryer to prevent corrosion and ensure the thing is really dry. It could be in general the inside is corroded. Do they show evidence of battery leakage? If so this quite often makes the beyond repair vs buying a used one.
