Hi

This truck will not start up after keyswitch on , if i pull the fuse 15A on the top of the black controlbox on the rear left side many times out and in the contactor comes in and everything works oke. If i set keyswitch out the display goes off and couple of time later i set the keyswitch on ,the same problem.

I think a capicitor fault in the box?

On the right side on the rear i have a grey box.

Truck give not a fault for this problem
