Polar 78X main motor will not start

Hi all,

Polar 78X main motor will not start. All other functions work. No error codes except normal "clamp interruption" message when pressing cut switches.
Any ideas where to start?

Thanks

 

Ok found it

After checking with the night shift crew I received a lot more valid information and checked the "Q3" breaker ... bingo. Problem solved.
Now all I have to do is order a new pair of clutch handles ... don't ask!
