OK, I'll check that. The series 1N4148 on the battery line could also be open. I found the schematic. Had trouble downloading from github but finally got it. Thanks,

The SMD parts are assembled on a Panasonic pick and place. No chance of a reversed diode. What is, however, possible is that the DC connector, which is hand soldered, hasnt been soldered properly. Open up the box, unscrew the PCB and flow solder on the tabs of the DC connector from the component side. I covered this problem a while ago.
A video manual is in the works. I finished a few yesterday, I will start posting th3 videos over the weekend.

That would be nice. Mine works fine on the external power input but 6 brand new AA cells in the battery box (9.56V) wont even light it up. I did check and have the 9+ volts on the PCB terminals but without a manual and current schematic I don't want to take it apart. Not really a happy camper right now. Farhan take note I suspect an open or reversed diode but without a schematic I can trust, I don't want to destroy it accidentally.
This may not be going to the right group.
Is there a manual available for the Antuino? My unit arrived today.
I thought I joined the Antuino group but I see the last posting I received was on 8/17.
