Grounding IS always the Very First line of troubleshoot..as well as corrosion Control and proper bonding...Clean the sockets from corrosion, as well as the socket pads the lamp rests on, and inspect spring preload....be sure the ground sides are properly bonded to a CLEAN, Burnished , Hard ground, and use a proper star washer and lock washer. Sometimes we assume (because it automatic to us ) That it has always been checked first..and overlook posting that as a first step!
It may also be that what he has done (depending on the type Bulb he has in the tail Turn/ Brake lamp bucket) He has wired the wrong filaments..and has brake lamp / turn to the Lower (less bright filament) and tails to the upper (more brighter) filaments..He needs to check that..
Be sure the flasher unit is a 6 Volt flasher (not 12 volt, although it normally would not work or just hang on..stranger things have happened..)
How are the brake lamps? are they bright? that may be a clue as to the filament selection.
