I'm not sure, but is it possible the lever is turning the redstone conduit off in your picture, so no energy is making it through?
Of course, if you aren't using the lever anymore, I don't know what to tell you. Without seeing the entire setup it is hard to judge. I'd come see myself but I'm actually busy at work today, if you can fucking believe it!
On a side note, if anyone needs wand recharging, I've got a setup at my new base (right next to the old one, south of spawn if you aren't aware). Just please don't use the low level wands in it, as those won't save 1 of each aspect and might burn out some nodes. But anyone is more than welcome to use it at any time. I'll grab a few more in the future to make it even easier if multiple people use it.
