Tail chop performed, brake light doesn't work
Offhand, in most bikes, the tailight and the brake light are integrated in a single bulb with a common ground. This would translate then into a 3wire arrangement. The brighter of the filaments is for the brake while the dimmer of the two is for the park/running/tail light. To my knowledge, either the tail or brake lights do not use a relay, they are wired straightforward. Your described problem all points to a mis-connection, possibly the ground wire. The easiest approach would be to identify the ground wire. With ignition switch off, all light switches off, identify the ground wire with the use of a continuity tester (VOM/DVM). Disconnect the wires to the harness, on the harness, it would be the wire with nearly 0 resistance against any exposed metal or the chassis. On the wires going to the tailight assy, it wold be the wire that measures 0 ohms to the metal socket/housing of the bulb.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
