Section 4 – Troubleshooting Information Electrical System
6. Voltage out of range at valve driver pin #14. Check voltage while operating jib down. Voltage
should be 4.83 volts. Refer to toggle switch voltage
reference worksheet in section 5 if out of range.
7. No output on pin #23 of the valve driver to wire
#20A.
Check pin #23 for proportional voltage. This
voltage varies with the A3 boom speed control. If
no voltage present with foot on footswitch check
section 5 for OCM pin voltage reference.
8. No output on pin #7 of the valve driver to wire
#34 at the platform terminal block.
Check pin #7 for 12 volts. If no voltage present with
foot on footswitch check section 5 for OCM pin
voltage reference.
9. Loose or broken wire #34 or #02 from platform
terminal block to jib down valve 4H-34.
Check continuity. Replace if defective.
10. Defective jib down valve coil 4H-34. Check continuity and resistance through coil.
Replace if defective.
4.2-34 No Jib Rotate Left from Platform Control Console
1. Loose or broken wire #08 from platform terminal
block to jib rotate switch S10.
Check continuity. Replace if defective.
2. Defective jib rotate switch S10. Check continuity through switch while activating
rotate left function between wires #08 and #42.
3. Loose or broken wire #42 from jib rotate switch
S10 to platform terminal block.
Check continuity. Replace if defective.
4. Open or defective diode D42-1. Check diode. Replace if defective.
5. Loose or broken wire #42A from platform
terminal block to valve driver pin #15.
Check for 12 volts at pin #15. Check continuity.
Replace if defective.
6. No output on pin #23 of the valve driver to wire
#20A.
Check pin #23 for proportional voltage. This
voltage varies with the A3 boom speed control. If
no voltage present with foot on footswitch check
section 5 for OCM pin voltage reference.
7. Loose or broken wire #42 or #02 from platform
terminal block to rotate left valve 4H-42.
Check continuity. Replace if defective.
8. Defective rotate left valve coil 4H-42. Check continuity and resistance through coil.
Replace if defective.
