Thanks for your reply! Appreciate it!

Yesterday I already measured the H board and found one of the Fet's was faulty indeed. (fet for switching left motor winding)
Waiting for parts now, it's a p60nf10 FET and I will try my luck after replacing it. Other parts on H board measure okay (lso measured the cables to the motors and the windings).

Kind regards,
Eric
