2013 Touring with about 90K miles. About a month ago, after sitting in the garage for a week, the lights would come on, but not enough juice to turn over the engine. Charged it and everything is fine for a couple more weeks until... once again... couldn't turn her over. So I charged it up yesterday and did the parasitic drain test today. I'm getting about .04 amps draw with the multimeter bridging the negative battery terminal to the disconnected negative cable and everything off. Then I reconnected the battery and tested voltage across several fuses and found that fuse #23... "Backup" ... was giving me a voltage reading. So I pulled that fuse and again disconnected the negative terminal and amperage draw is zero. So I know that something connected to #23 is the issue. Now I'm here asking if anyone is aware of any common issues related to this circuit that I might look at before I bring it in and cough up the cash to have the Honda guys take a look.
