I don’t think this is right. Look at the photos in the eBay listing and you can see they have hooked up: 1. Power supply (battery) to “+” and “-“. Disconnect the battery from everything else. 2. Connect “+ load” and “- load” where the battery used to connect. It might not hurt to put an inline 20A fuse in the + line between battery and meter. Just in case.
