What Causes the Generator Indicator Light Not to Illuminate?
1 Answers
The reasons why the generator indicator light does not illuminate include a short circuit or poor contact in the charging indicator circuit, a faulty charging relay, or issues with the alternator and voltage regulator. Short circuit or poor contact in the charging indicator circuit: This could be due to a short in the power line of the charging indicator, a burnt-out bulb, a blown fuse, or a loose plug. Solution: Replace the bulb or fuse, and securely reconnect the plug. Faulty charging relay: The closing voltage of the charging indicator relay contacts may be adjusted too high, making it difficult for the electromagnetic force generated by the coil to close the contacts; the charging indicator relay coil or neutral point line may be open, leaving no voltage across the relay coil and preventing the contacts from closing; the charging indicator relay contacts may be burnt, oxidized, or dirty, leading to poor contact. In this case, the alternator may still generate electricity at a certain speed, but the output current will be insufficient due to the low excitation current. Solution: Seek repair at a service center as soon as possible. Faulty alternator and voltage regulator: The voltage regulator contacts may be burnt, oxidized, or have poor contact. Solution: Seek repair at a service center as soon as possible.
