VALMET 921C Breakdown

#431666 Dear All,

I have got a skogmaskiner VALMET 921.C
Yesterday she stopped and still it's not possible to restart it.
If I shunt electrical relay, it is possible to restart but the header can't work in those conditions.

Have you got idea of problem or the failure?

Thanks in advance for your help.

#431676 Hi,
Do you mean bypass the start relay?
Often there are more than one relay in series that makes a serie of conditionals for the machine to start. Maybe you have another relay or fuse that does not work, e.g shut-down relay in case of fire?

Best of luck!
