HWH control boards - LEDs

I'm digging into another issue and I was hoping someone my have some answers. 

I have 2 red LEDs that won't go off (my pic shows a red and amber, but now they are both red).  Each board seems to have (up to) 10 relays, each with a fuse, a red LED, and an amber LED.  What's the best way to find out which board controls what, and what do the LEDs mean?

I assume each slide probably has a relay for inflate, deflate, extend, and retract?  Then more relays for each airbag?  Relays for tag as well...?

On the inside of my cover there is a schematic of LEDs and operation
You need to determine which system your coach has. HWH HAS online manuals and once you find the manual for your coach they are very helpful.

I don't have schematics, but the underside of the control box has a sticker showing model AP34263.  I hit the Googles and came across  this pic.  Tag Travel Contact and Travel Contact.

However... after the whole charging process and removing power from the aux compressor (not sure if either are related), I'm now able to get into Travel mode.  I brought her home today to winterize (we're expecting a freeze in Galveston County early next week).  While checking on this issue again, I notice both LEDs are now off.  Doesn't necessarily make me comfortable though.

Anyone know the function of the coil and contact?
