tested the GLP

Repaired the green laser pointer. Well. Repaired is not the right word. Verified... When I opened it, I found the batteries inserted the wrong way (positive toward the emitter). I checked the voltage of the alkalines: both very good at over 1.5 volts. Verified the button was actuating the switch inside. Inserted the batteries. Fired it up. Bright green beam.



Made a new sticker, to show the polarity.
