Thomas Spagnoli: workshop approach for Aprilia Tuono 1000 main relay clicks but injector power is missing
My workshop rule for Aprilia Tuono 1000 main relay clicks but injector power is missing is simple: prove the basic condition first, then decide whether the clever part is actually needed.
If the result changes hot versus cold, or under load versus idle, write that down. Those conditions are not noise; they are clues.
If you are new to this, join the free Motorcycle Mechanics Course on the platform. I made it to explain the workshop logic behind cases like Aprilia Tuono 1000 main relay clicks but injector power is missing, not just to list random parts.
Bring one result at a time and the forum can narrow it down properly. That is how a thread becomes a real workshop note.
Small update from my side: I found one suspect connector and I am cleaning it before touching anything more expensive. I will post the exact result, even if the answer ends up being embarrassingly simple.
