Yes, fitted on a D3-110.
There is a rubber push button under the Valeo that you can hold pushing trying to start.
The push button make a manual contact between both big wires. If your engine starts when you make a manual contact, the solenoid has a problem.
You can remove it and open it (remove the two small screws and after remove the plastic cap) You can adjust the contact (there is a nut between two springs).
I did that last week.
The solenoid is under the 12 v alternator
