Foster dog is recovering nicely. But I've been with her 24/7 since I got her back and I'm exhausted. I hope she can sleep alone tonight, because my own dogs miss me and I want to sleep in my own bed tonight.
The battery bolts came in the mail yesterday and... they fit! I need to get some pipe cleaners tomorrow and clean out the bolt holes, though - looks like mud daubers had set up shop in them some time ago and they are full of dirt.
I'll also try to play with some floor plans for a dome tomorrow and see what I can come up with.
Update: To help alleviate some confusion (mostly mine), click here to see what my batteries are. Please note where it says "Terminal Type I2-Thread lead alloy recessed terminal to accept M6 bolt"
I will try to take a close-up picture of one when I get to cleaning them.
Update 2: Ok, here's a pic of my batteries.
The one on the right is exactly how they came to me. The one on the left, I have inserted the bolts I bought. There seems to be a "stop" inside the socket, so there's a gap between the hex nut and the face. This begs the question, do the cables I use for the parallel connection go under the hex nut, or between the hex nut and the wing nut, or does it matter?
