Trace Inverter AC-1 loss
I previously posted under “wierd electrical” as additional info
one of the relays in the shore power junction box has a red light. I tried swapping the relay next to it and it “buzzes”
** just found out why the buzz-one is 12v the other is 120v( could not see thru the marks a lot)**
I did check the ac line 1 at the inverter and indeed no voltage, but there is voltage in
the inverter breaker panel( on all legs) will post pictures of each panel.

UPDATE!Thanks to suggestion from Ed( Travelingman) I did a “whole coach -shutdown” and it solved the problem. The relay still has a red light ,so will try a new one when it arrives,

Jim,
This is the fan temp switch at my inverters Coach #632.
-
Located between inverters. This fan switch controls the temperature that the Marathon installed fans come on to push and pull air out of compartment. I added two more fans to keep inverters cool on hot days or when they are hot. Switch is set as marked in picture.
-
Mine is mounted up above the inverters and the snap disc was set a high temp, so for you Marathon guys, check the temp setting and lower it.

Update ( again) I replaced the relay that had the red light and new one did not light up. The relay is labeled “inverter loss”
While I was having trouble understanding why #1 inverter was carrying more load, and for the last couple weeks before they shut down, I was seeing battery voltage drop,
Now after the reboot, the load is higher on #2 inverter, but batteries remain at 13v &26v.
Thanks again for the replies.
Note– wrong picture, this was during “Bulk charge”
