| Component part | Description |
|---|---|
| Alternator (IC voltage regulator) | IC voltage regulator controls the power generation voltage by the target power generation voltage based on the received power generation command signal. When there is no power generation command signal, the alternator performs the normal power generation according to the characteristic of the IC voltage regulator. |
| Battery current sensor | Battery current sensor is installed to the battery cable at the negative terminal, and it detects the charging/discharging current of the battery and sends the voltage signal to ECM according to the current value. |
| Combination meter (Charge warning lamp) | Combination meter indicates charge warning lamp judged by battery warning request signal. |
| ECM | Battery current sensor detects the charging/discharging current of the battery. ECM judges the battery condition based on this signal. ECM transmits battery warning request signal to combination meter. Refer to Component Description . |
