Battery & Brake Light Stays On

If the charge light is on when the engine is running it means that the battery is not being charged by the alternator. You can put an ammeter in series with the positive terminal of the battery to see if indeed the alternator is putting out current. Otherwise, go get an electrical system test and they'll likely find that the alternator is not working. The brake light being on simultaneously with the charge warning light is an artifact of the warning light circuitry on many Japanese cars. Get the charging circuit working and the brake light will go out too. Good luck. Al

The alternator needs replacing.
