I have a new to me 2014 CS-S, and been trying to fire up the ALDE (analog control) on shore power alone. Like others have said, there is a 120V side to power up the heat coils, but there is also a 12v line that comes from the converter box. (which I assume is for the control circuitry.) As a new owner, on a trailer that did not come with a manual, or labeled Circuit breakers and fuses, I have been "ringing it out" to find out and label which fuse or breaker controls what. In the process, I disconnected the ALDE 12v power connector from the circuit board (between the 2 small fuses) and connected to the multimeter. I went through fuse by fuse looking for the magic one that controlled the Alde. to my surprise, there was no fuse in the main electrical box that disconnected control power to the ALDE. I did notice when the 20A fuse was removed the voltage dropped by a couple tenths but remained steady. the only fuse that caused power to drop to the ALDE control wires was the 30A Main fuse which killed all the 12V. Is it possible that the ALDE 12v supply is wired directly to an unfused output from the power supply? if that is the case, then the ALDE unit gets inconsistent 12v every power cycle as the converter comes up. I am contemplating adding a 2 pole switch on the wires leading to the ALDE control card so power can be completely killed. this would allow for the power converter to wake up before I connected power to the ALDE. Does this make Sense? Can anyone agree or disagree with this theory? Can anyone confirm or deny that the ALDE 12v control wire does NOT have a breaker upstream at the panel? And if you have a 2014 I would love to know what you have discovered or the factory has said about main panel lay-out and labeling. (what fuse controls what) Thanks!
