Greetings to all members of this blog. I am currently helping a friend with the electrical system of a JD excavator.Mod. 690D LC. Serial#. 526138. I had to repair all the wiring in the cabin but the board that monitors all the sensors has the first three diodes of the board D1,D2,D3 blown up. The problem is that I have not been able to find the schematic on the internet to identify the values. I would like to know if there is anyone who can help me in this matter.

I will be very grateful for any help you can give me.
