Section 4 – Troubleshooting Information Electrical System
4.2-30 No Platform Rotate Left from Platform Control Console
1. Loose or broken wire #08 from platform terminal
block to platform rotate switch S11.
Check continuity. Replace if defective.
2. Defective platform rotate switch S11. Check continuity through switch while activating
rotate left function between wires #08 and #36.
3. Loose or broken wire #36 from platform rotate
switch S11 to platform terminal block.
Check continuity. Replace if defective.
4. Open or defective diode D36-1. Check diode. Replace if defective.
5. Loose or broken wire #36A from platform
terminal block to valve driver pin #17.
Check for 12 volts at pin #17. 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 #36 or #02 from platform
terminal block to rotate left valve 4H-36.
Check continuity. Replace if defective.
8. Defective rotate left valve coil 4H-36. Check continuity and resistance through coil.
Replace if defective.
4.2-31 No Platform Rotate Right from Platform Control Console
1. Loose or broken wire #08 from platform terminal
block to platform rotate switch S11.
Check continuity. Replace if defective.
2. Defective platform rotate switch S11. Check continuity through switch while activating
rotate right function between wires #08 and #37.
3. Loose or broken wire #37 from platform rotate
switch S11 to platform terminal block.
Check continuity. Replace if defective.
4. Open or defective diode D37-1. Check diode. Replace if defective.
5. Loose or broken wire #36A from platform
terminal block to valve driver pin #17.
Check for 12 volts at pin #17. 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 #37 or #02 from platform
terminal block to rotate right valve 4H-37.
Check continuity. Replace if defective.
8. Defective rotate right valve coil 4H-37. Check continuity and resistance through coil.
Replace if defective.
