Junction Boxes F and R

These junction boxes are located on crane modules. They sensor inputs and control hydraulic valves on the crane modules.

The circuitry layout of the F and R boxes is identical.

Key:
A	ECU supply voltage LEDs (green). LED3, UE, is lit continuously when the the SMARTlift system is operational. LED4, D+, is only lit when the green button (horn) on the Hetronic radio remote is pressed.
B	Fuse LEDs (red). For LED1, Angle Sensor Ground, and LED2, ECU UE, a lit LED indicates that the fuse is blown.
