Air Conditioner leaking inside...questions

ok after following that link which I did not see until after my first reply...it says to remove that evaporator cover which I was tempted to do each time but was afraid of shock...so I may get up there again. it has a warning on unit that even if turned off you can still be shocked...I assume unplugging the whole RV from elec would avoid this from happening...it is a bit difficult doing this with only one person as it might be helpful to have it turned on once the shroud is off and evaporator cover off to see where the water is coming out...I do not want to have it running while I take the shroud off...hum challenging!;)

oh yes and it has nothing to do with the rain
