The battery voltage may fluctuate when viewing this information on the DIC. This is normal.
If there is a problem with the battery charging system, the charging system light illuminates and/or the DIC displays a message.
See Charging System Light, Battery Voltage and Charging Messages and Battery Load Management for more information.
