Safe owner checks

Stop safely when the manual instructs or power is unreliable.
Do not touch a moving belt, hot components or damaged electrical parts.

Questions for a qualified technician

Does the vehicle use an alternator or DC-DC charging architecture?
Is the battery, charging supply, connection or an applicable ICCU campaign involved?

Common wrong turns

A battery-shaped lamp is not proof that a new battery fixes the problem.
Not every EV auxiliary system is a conventional 12V lead-acid system.

Confirm the repair

Verify charging performance with the correct vehicle/chemistry requirements.
