Hey Paul,
Stop/turn signal light functions typically use the same wire and the running lights are on their own. You'll want to go to the passenger side and check the running light wire for power with a multimeter # PT89ZR. If you aren't receiving power at the light then you'll trace that wire back to the power source looking for damage and checking for power until you find where it stops.
With this being a boat trailer I would typically just rip out the old wiring and start with new wiring # A30WB because a lot of the time the casing for the wires melts inside the frame and then the exposed wire shorts to the frame. You typically can't find the issue until you really rip it all out and with wishbone wiring harnesses being so cheap it's worth it to just replace it instead of wasting your time.
