The biggest problem with making an interactive electrical cache is providing a reliable power source. But if you bring the battery, we both can have some fun!
Please note, this is a Multi cache. There is a gizmo hiding at the waypoint that will yield the co-ords of the cache when tickled the right ways with your nine volter. (Remember, you will need two numbers...) If you can't find the gizmo, or it won't work for you, the final cachebox hiding spot isn't hard to find. It's lurking in a 'Candy-Booted' sheltering spot quite nearby. No bush-bashing required! And it isn't hiding!

A WORD OF WARNING ABOUT 9 VOLT BATTERIES!: Don't allow the terminals to come into contact with metallic objects! This will short circuit the battery and flatten it. It will also create a fair amount of heat. So putting your battery in the glovebox or your pocket with things like keys or spare change is not a good idea.
I've left a pack of 3D printed 'keepers' in the cachebox that will save the day! Take ONE for your battery.
