Thomas Spagnoli: workshop approach for Moto Guzzi Breva 750 rear brake light stays on after pedal adjustment

Before buying anything for Moto Guzzi Breva 750 rear brake light stays on after pedal adjustment, I would build a small test path. The cheapest repair is often the one where you do not replace a good part.

1. Inspect the physical installation first: clamps, brackets, heat shields, routing, grounds, fuses, and connector strain.
2. Measure voltage drop under load on electrical faults; for exhaust faults, listen for leaks at the head and joints.
3. Do not ignore heat. Melted plastic, brown terminals, blue pipe sections, and cooked insulation are evidence.
4. After any repair, test hot and cold. Many electrical/exhaust issues behave differently once everything expands.

The best next step is the one that can prove something. A test that only creates another guess is just a more expensive guess.
