How to install a new unteli-power 9200 converter? The old magnetek converter has 3 wires in the back, black,white, and red on the new one there is no black wire so I disconnected from the source. I connected red to positive, white to negative. When the power was resumed all lights worked except converter began to buzz and lights dimmed and 12 volt
panel clicked rhytmically. What,s wrong? Removed all bulbs and turned off all appliances continued to click and buzz.
