Dash lights will not turn off!! 72 dart

Got a weird 1, been having lots of issues with oriellys alternators been through 4 because they are junk the last 1 jumped up to 18.2 volts at 1 point on my voltage gauge and maxed out the alternator gauge on the dash, switched over to autozone alternators no problem so far but now my dash lights will not turn off on my 72 dart after that alternator did that, it's intermittent but it's been draining the battery and not sure where to look, I tried the headlight switch because thats what caused them to turn off before playing with the dial but I reached in the dash and un plugged the switch and they stayed on, ive looked over the basics so far making sure i got no melted wires or pinched together wires and so far have not seen anything, have not pulled the instrument cluster it's self out yet, I have a car show tommorow so I just disconnected the battery cable for tonight, included a pic of the back of the instrument panel I can access without pulling it, since I haven't got to that yet and the voltage i saw on my voltage gauge, i also replaced the voltage regulator with the alternator and everything has been fine since then other then the dash lights problem
