The only wires I see do not seem to lead to a visible sensor. The battery has a molded together red, black and blue wire as well as a red wire that leads directly to the controller. The larger single orange wire leads to the Try Me button on the left hand. There is a single orange wire and white wire coming out of the controller that is then plugged in to what looks like something that splits
into a white/orange wires which I'm assuming go to each eye.
OK, there it is in the side pic. The silver disc with a hole in it is an electret mic. The prop is sound activated. With the switch in the ON position, try clapping right next to that mic. If it doesn't trigger, something is wrong with the controller or the wiring to the mic.Front and side of controller
I will try to take it apart. Yes it worked last year. I do recall it got wet in the rain though.Sometimes you will have to disassemble a prop a bit more to see exactly were everything is going. It is really difficult to diagnose something like this because you want to turn it visually but can't. Can you disconnect the try me button? I have had props where I had to remove it before sound/motion worked. Did it work before?
Activating when the switch is turned on is typical in some of those type of props.I tried clapping but nothing happens. I guess I will have to take it apart to look inside. So, the fact I can turn the switch on and it will activate doesn't tell you anything?
