Let's wedge this hot potato out of this place!

Hhhhhhhmmmmmmmmmmmm...

Canon had done a very good job insulating the circuit on the top half.

The wires lead to solder joints on the board, which are exposed.

You could take voltage measures from here, but I didn't really get any reading from the multimeter. It reads 12.7V, if I remember correctly.

Perhaps the different lights require different voltages and this one is more docile. or ... perhaps the circuit is only charged when a flash is imminent
