I just bought a cc120 Dynapac Roller and the vibratory is not working. The past owner said that it worked before. Give me a coupe ideas of why it is not working ? When I took apart the console to see if there was any loose wires it seemed to be ok just dirty. The fuse box or board what ever you call it had only 4 fuses in it and the rest were missing.
Mechanic: Dan, Technician replied 1 month ago
There should be two switches inside the console box that activate between forward and reverse of the forward and reverse lever that depending on the position of the forward and reverse lever will depend on the intensity of the vibration and also the engagement as those cams on the micro switches get close or further apart which will ensure vibration is engaged at the same speed and both forward and reverse. That would be for automatic mode and on the forward and reverse lever itself there should be a thumb switch on the end of the lever to manually engage your vibration. If not working I would do a continuity check with your own meter to test for any open circuits in the switches and wiring harness. Look for any damage or corrosion in the wiring or connector pins and test the switches for continuity both open and closed positions. Also check your relays and the connections for the relays as well as run a fuse test to be sure there are no blown fuses. If the electrical test good on the control side and the fuses and relays then move on to your solenoid to verify power at the solenoid valve to engage that function. Let me know the results and if we need to dig deeper into this as we can follow up as needed on here.
