Hello everyone. I'm new to the forum and I've come here seeking assistance in repairing a Gemmy Halloween prop I have. Its series name is "Grave Ravers" I'm sure you've all heard of it before somewhere. They're these small animated skeletons that dance and sing when the button on their base is pressed. I've had mine since about 2005, it sings "The Groove Line." However, it was put into storage in about 2009, and I recently uncovered it after all of these years. After examining it, I noticed a few things about it. The battery compartment has been corroded with battery acid (Taken care of), the left arm had been taken off of its gear, I'm assuming the glue gave way in the shoulder, and there is no movement whatsoever. Whenever I turn it on, it lights up and sings, but no movement at all. I can hear the motor or something whirring, but nothing is happening. Is there any way I can find the definite problem with it to get it moving again? Thank you.
