possible short in my circuit
I point to point soldered a circuit that I designed which contains two H bridges to drive two motors along with three servos.· Each servo's base is connected to an i/o pin of the BSII.· I think that I might have a short somewhere, or even a short across a transistor.· To test this, I programed the BSII with this.
do
pause 100
loop
When I put it into the circuit and hooked the battery in series with my multimeter, I got around 16 milliamps.· Is this just what the BSII is using to run itself or is there a short somewhere.· Also, is there a better way to find my short besides testing every single part of the circuit.

Could you perhaps post a schematic of the circuit in question??

Is going to do nothing...No I/O pins will be affected, the Stamp Module will just sit in an effectively endless PAUSE loop.· 16mA is no more current than 1 or 2 LEDs consumes.· I don't understand what the problem would be.· If you had a short, your current draw would be measured in A, not mA.· Plus you'd probably see pretty blue smoke, and maybe get burnt touching something.
