David, My bet is on the power sliding door unit. It is powered by Fuse #7. Mine had a constant about 400 ma drain when the door closer started flaking out (your 70 ma sounds a little low to really be a problem). I had dead battery twice til I pulled the fuse – no drain. Now just need to wait til Eric posts a video telling us how to fix it. I don’t trust the other youtube folks to tell me about all the little things that you need to be aware of and tips to make it easier. Eric is the man.
