After a lot of investigations (HI !) I found that there is a contact beetween pins 3 and 5? (K3) but there is not any continuity beetween pin 3 and M1 and beetween pin 5 and M2. But continuity is 0K beetween M1, 2 ,3 and 4 which is logical.
I discovered also that Q70 was fried although I changed it recently...
