A test light has a nice sharp tip & a graound with a small lamp in the handle. You can hunt voltage on a wire down the length of the wire. You can trace the wire that goes to the turn signal, between the flasher unit 7 the lamp socket 7 SEE if there is a pulsing voltage on the wire. If so, you trace the wire toward the lamp socket. Lets say you could actually get your hands on the whole length of wire & that there were several connections on the wire, down the length. You go to the end, NO Desired Voltage, then, go to the source, IF you have the desired output at the source( turn signal flasher unit) then, go half way toward the lamp & check, No signal? Go half way back toward the source, signal> Go back 1/2 wat the other way, called the half split method, it makes tracing a loss of signal somewhat more scientific & supposedly, less hair pullingly frustrating. Make sure your test lamp has a long enough lead(5 feet is good stuff, 3 is okay), a good ground clamp, not some pukey little "Roach Clip" looking piece O poo, and a good sharp probe.
