S-250 AN/TSM-183 New Project

[mil alta]

Have a S-250 AN/TSM-183 and looking for information as where to start.
Putting in a M-1102 hauled by my HMMWV
Can't find any info on the electrical system.
Looks like a 240 volt input down to 120 volt with an inverter to 12 or 24 volts.. Says it has a heater but I don't see it unless it's in the fan.
Any manuals around for this particular unit. Love to know what the item wired by the lower door. It's busted up on mine
What batteries are used in these?
You experts that can do this with your eyes close I'm sure are chuckling but I know the military doesn't follow common sense....wiring manuals good. lol

Have you looked in the TM forum? https://www.steelsoldiers.com/forums/misc-tms.122/

My experience with these shelters is that there are many, many configurations, each rigged for a specific purpose, and these myriad of variations are not laid out in the general manuals. There is likely documentation for each shelter setup, but that seems to rarely make it out to us.

The broken thing by your door may be the blackout switch - it either turns off the interior light when the door is opened, or switches to dim lighting. There seems to be a lot of variation in those too.

Cheers
