• (97-683) The K51 readiness indicator lamp and the K52 battery charge indicator lamp above the 12.5 V indicator should light.
• load the battery on a battery tester with a current consumption of no more than 110 A. When the battery is discharged, the green LED K52 should light up first, then the yellow LED K53, and finally the red LED K54. Already at a battery voltage of 12 V, the red LED should light up.
