I recently found an old Nikon SB-16 at my mom's house. When I went to put some batteries in it to test it I noticed that there was no metal on the battery door (see pic below).
How can I test to see if this thing will still fire? Do I just need to metal on the contacts of the battery to complete the circuit?
I apologize if this is a really stupid question. bit I would really like to get this thing working as a secondary flash if possible.
