Refer to Figure 158 to identify each individual fuse and its correct amperage.
The fuses have the following functions.
F1-1 (15 A): Protects starter circuit power supply.
F1-2 (10 A): Protects main power supply.
F1-3 (10 A): Protects power supply for headlights.
F1-4 (10 A): Protects power supply for power point.
F2-1 (7.5 A): Protects power supply for TEC outputs.
F2-2 (7.5 A): Protects power supply for TEC outputs.
F2-3 (7.5 A): Protects power supply for TEC outputs.
F2-4 (20 A) (if equipped): Protects power supply for the optional air ride operator
