I recently did the capacitor replacement repair on a PLM that had failed. It did not work initially because I just did the Restore Modem operation without having power cycled the ISY because I did not realize that was required. I have relied on the User's Guide document as my primary reference, but it provided no guidance. Finally I found this thread, then it worked.
Why doesn't it describe the PLM replacement procedure? It doesn't even explain the Restore Modem command.
Better yet, why doesn't Restore Modem cause the ISY to go read the PLM ID first?
