Ok I have got the polarity light to turn off it was the auxiliary cord I was using. I think the female end. Now here is the next part of this deal on the panel there is a L120 and R120 prior to changing the R120 would shine bright the L120 would be dim or flicker. So the question is what does the L120 And R120 mean since I am plugged into 110volt,15 amp.
Those lights are notorious for dimming and flickering or just going out especially if the voltage is even a little low. The adapter cable is designed to direct the 120 volts to both 120 volt legs in the coach or else 1/2 of the circuits would be dead. However, you are still limited to the max current of the circuit you are plugged into.
Mine are labeled L1 and L2, if your are labeled R120 and L120, I would presume that would mean Left and Right.
