Could this be caused by the battery being dead or bad battery cell.
It has been plugged in for several weeks now.
Ok, being the cynic I am on new power installations, let's start there and work forward. The reason for this, is we have seen TOO many times that an electrician wires the outlet for 240 volts and ruins many things. Your RV is only 120 volts.
Do you have a 50 amp (4 prongs on power cord) or 30 amp (3 prongs on power cord) RV, and did the electrician wire an outlet for same (50 or 30) or are you using an adapter?
Do you have a microwave in the RV, and if so are the lights on (clock, etc)?
If the electrician incorrectly wired your RV for 240 volts, it will almost always fry the converter...which is what powers your lights and other 12 volt things as well as recharges your battery. With a fried converter, your 12 volt stuff will still work directly off of the battery up until the point it is depleted....since there is no way to recharge with a fried converter. You may have had lights initially, but once the battery ran down, then they also quit working.
Until we ascertain that you have a correctly wired outlet, please do not attempt to turn on the air conditioner again as you will damage it, as well as anything else you plug into an outlet inside the trailer that works off of 120 volt AC power.
A 240 volt installation will usually always take out the converter, and more times than not, the microwave and televisions if equipped.
