Swapped batteries in the dripbox and it was just dead all of a sudden, tried another and still nothing. Looked inside and saw this:
I'm guessing this o-ring goes around the positive contact but not sure how to get it back on there. Tried pushing it back on with a knife handle but it just fell out. Any ideas what its there for?
Maybe you can try using a wooden skewer like you use for a shish kabob? They are pointy on one end, nice & long, I use them for all sorts of things. I'm thinking that o-ring is some kind of insulator for the battery contact?
