Repairing the sound on a toy truck

A recent family road trip took us to the Virginia Safari Park in Natural Bridge, VA.  The kids had a great time, and on the way out, we purchased a small toy truck.  Unfortunately, after we were home and unpackaged the toy, the sound would not work.  We ordered the world's smallest batteries on Amazon (LR41s, as who keeps those on hand);  After replacing the batteries, things were still not working properly.


After removing and disassembling the box which appeared to be the sound source, a disconnected wire was found on the piezo speaker.

 

A second or two from a hot soldering iron put the wire back in place, and the sound was functional again.


The last trick was re-assembling the case.  Since the iron was already hot, I just melted the plastic a bit and that seemed to do the trick.



The box was snapped back onto the truck and returned to a very happy 3-year boy.
