Hi quick yes or no question. I have a 2204t that is being worked on and the mechanic wants to know if the 12v is always on or is it controlled by the black switch? Thanks!

The 12V supply to the interior lights, water pump, furnace, fan(s), etc., is controlled by the 3-position Master Switch near the Raise/Lower switch. I don't know what color yours is.

The master switch placed in the middle position kills 12v to everything except the refer (when in the DC position). On mine the carbon monoxide and smoke detector are 9v batteries, not 12v. Hope this gets to you fast enough.
