Bomag 120 ad 3 vibration issue

[omal1989]

Hey guys ! I have a bomag 120ad3 . And the electron end of the vibrating won’t engage .no power at solenoid. Button is working , then it’s down to the silver relay box . Is there a way to text the function of it ? . Can I easily just run a few feed from the battery to the button to the solenoid and bypass all the electronics on the roller . Thanks in advance ,

How about a complete machine serial number. Also need tom know the specific model number. Maybe post a picture of the serial plate. Is this unit an 120AC, AD, SL, -3,-4 -5, etc. Need those questions answered for accurate information gathering.

That is an old roller. Bomag does not publish a schematic for something that old. I sent you the closest one they have. It should be the same.

Did you check the F46 fuse?

there’s miscellaneous fuses and I’ve checked them all , all ok . It could be the relay , I’ll test it

If I am not mistaken, the relay you have pictured is actually a module, and that is controlled by a relay, which in turn is controlled by your switches. The schematics I sent should help you sort it out.
