Battery Packs Not Registering any Voltage


#1

Just went to test the DB-25 connector.

All batteries are fully charged and show 3.7V on multimeter, but no voltage at all showing on the DB-25's end. Even when I just test the two battery wires no V is registering on multimeter

Is there something fundamental I could be missing, checked instructions and all soldered and wired exact...?

Thanks in advance!

have you checked that the wires in the tubes are not just holding the batteries away from the terminals?
Happend to me...

Solved: Used multimeter to test battery tube to db-25 and found wires soldered on wrong pin
