Just installed a MultiPlus II 12/3000/ 120-50 in my RV. When the charger ramps up into bulk mode its unbelievably loud. I loosened up the cover screws and it helps but still unbearable. This Multiplus is located directly under my bed. I have looked back at noisy MultiPlus posts and I don't see an answer. Can someone help? It is installed horizontally if that matters. I am sure the cover making the noise.
