hi,again, OK got the wall down and the converter out and disconected, 13.7 volts with no load for 20 mins. good. Reconnected turn on same lights as last night, w/o batteries, and it goes form 12.7 to 14.8, back and forth, hard to read DVM so fast, and the converter is clicking like mad. Since WFCO is not the best, should I replace with the same, 90 percent of the time we have shore power when we park. Seeing we are on the road, in so. ca. right now, any suggestions for where to get a converter arround here. Thanks, Dan
