2 sets of fully charged batteries.

No blue light with carto. no blue light without carto.
I've tightened the cap screw, I've loosened the cap screw.
I've looked inside for loose connection. I tightened screw inside cap.
I've cleaned, I've tried new cartos, I've tried all combinations of switching the batteries.
I've smoked a cigerette
HELLLLLLLLLLLLLLLLLLLLLLP
