possible short circuit in schematic design?

at point A.. the output.. i get 001 at 2000m V on my multimeter. at point B i'm getting about 14v. something is obviously wrong. and the batteries are heating up. no wires are touching.. is it possible a switch is bad or somthing?

What is "001"?

If I understand the circuit correctly you have an open circuit when nothing is connected to the piezos. 2000mv (2V) could be normal. And, you can't reliably measure PWM with a digital multimeter.

at point B i'm getting about 14v.

That's a little low for two 9V batteries. Try breaking the circuit and measuring the current.

Also, make sure that C5 is not reversed.

Is the IC in a socket? If so, try removing it to see if the voltage goes up, and the current goes to zero.

What did you resolve for the last issue on this circuit?
