Combines lexion electrical plugs

We are running a 465 with a little over a 1000 hours on it. So far we have not had any electrical problems. The printer fell apart about 400 hours but that was mechanical, not electrical. I have wondered about dirt and dust buildup around the base of the electrical cabinet (next to the cab). So far blowing it out with a leaf blower has kept it fairly clean. If you find the fault I would like to know so we can take some preventative actions.

might not be the actual board, seemingly after a few days the hydraulic cylinder for moving the chopper can lose a small amount of pressure and this then tells the computer that the chopper is stopped, but only on a few combines seemingly, just hold down the chopper engage button to pump up the pressure again and that would sort it. May also be the speed sensor gap setting is wrong.
