To make sure your camera will even function with a new battery, before you solder these connections, test your 4.5v source with the camera.
Cock the shutter. With something covering the electric eye, push the shutter button and hold it. You should hear a single click. Wait a second or two, and remove your finger from the eye. If you hear a second click soon after, the camera is working. If you only hear 2 very fast clicks no matter what you do, the power is not reaching the circuits.
One click is the shutter opening, the second is it closing. Test different lighting situations and listen for the differences in timing. Bright light should make the clicks closer together than a dark place.
If everything works well, move on.
Solder the white wire to positive, the black wire to negative. Just for cleanliness sake, use some hot glue to seal the connections.
To get the holder to fit, remove extraneous plastic from inside the compartment.
Depending on your model the holder may or may not fit easily. But trust me, I have not run into a compartment you couldn't somehow fit a 3xAAA holder!
