Yep, I killed a brand new http://www.powertechnology.com/ppm.asp?model=PPM
Anyone familiar with this circuit? I accidently shorted across the R18 resistor while adusting the power output and now I get nothing at all. The TEC fan runs but the laser "off" light doesn't come on and there's no laser light coming out.
I'd like to find out if I killed the controller or if the diode blew up.
