Schneider XW6848+ Cleanup

Thanks, but that link doesn't seem to work. It asks me to choose a region/language, then dumps me to the Schneider home page.

I see what happened. I had posted the link in a reply earlier in this thread, but when I copied the URL from there to post it again above, it copied the shortened version shown on the screen rather than the full URL.

Thanks for sharing the XW maintenance manual, I have XW Pro but I think they are similar.

I ran the generator for 1.5 hour. The input voltage was oscillating between 228.9 and 231.9V, but was mostly stable at that upper value. Was charging (80% max charge rate) at around 110amps until absorption was reached. I've not had a single FET1 over temperature warning. So cleaning the filter likely fixed the issue. Thanks folks for your help, much appreciated!

For what it is worth: 1) heat sink paste ( on cpus & almost all power elex heat sinks) do dry out after many years.
2) on an outback Radian, I was getting very high Temps ( xfmr and thyristors). Found one of the 2 fans had failed. The second fan was rubbing and about to fail. Replaced both and then found the 12vdc power supply for one was dead. I used an AUX 12vdc until I could get the circuit board repaired.
