The IPC provides a charging system gauge to inform the driver of current battery charge and charging system status. The IPC utilizes the B+ voltage input to generate a charging system gauge indication. When the voltage level is equal to or less than 8 volts, the charging system gauge displays in the low range. When the voltage is between 9.6 volts and 16.9 volts, the gauge displays in the normal range. When the voltage is greater than or equal to 18 volts, the gauge displays in the high range.
