1st & 3rd string of Christmas lights in a chain work but 2nd doesn't

I have a fake Christmas tree that came pre-strung with Christmas lights that my family has been using for several years. The tree comes in 3 sections (bottom, middle, and top) with 2-4 strings of lights wrapped on each section.

"If it is wired in series, which it sounds like it is, one bad bulb will stop it. Use the working string and pull on bulb. Now use that to test the bulbs on the bad strings.
