Trailer manuals typically are real generic and tend to not offer any usable info.
For your vintage I would be doubtful that you are going to find New Old Stock of the manual and even used copies are going to be as scarce as hens teeth.
Your brake/turn/running lights are actually rather simple.
The Brake/Turn shares one wire the running lights is one wire and each fixture will have a ground wire going to the frame.
Some trailers have a small fuse box up near the tongue of the trailer which will have fuses for these functions.
I would suggest removing the lens on the offending tail light and remove the bulb and clean the socket. Bulb sockets often corrode and corrosion will prevent the bulb from lighting.
Check the connector on the cable going from the trailer to your vehicle for badly corroded connections. These connectors often get badly corroded and sometimes the blades will have corroded so bad it is gone.
Additionally you need to check to see if the connector is wired correctly. Over the years there has been several different ways the wires have been connected and some folks have even wired the connectors any way they felt like it..
Do a search for 7 pin RV/trailer wiring diagram.
Check the wires going into the fixture, make sure the wires have not corroded.
If none of that works then you can try temporarily running some wires from the tongue junction box to the offending light and see if the lights work. Try a temporary ground wire from the fixture to the frame also..
