Thank you both for clarifying:
1) The indicator light does NOT indicate that "ELEC" is operating...and...
2) There is no control board on the RM2601.

When on shore power AC, is it required to have a 12v battery on the tongue? (I thought the AC/DC converter would provide the 12v to this appliance? All DC fuses in bedroom fuse panel are good, and so far, all other DC electronics are working without problems).
What is powered by the fused line from the 12v battery?
Thanks in advance!! I am always rushing to do as much as I can when I have time to go work on the cleaning, restoration, and renovation (bedroom needs a new floor)....so that leaves little time for manually tracing wires. :(
