Hi All.
I am having a problem with traction with a EV-100 chopper controller;

the problem still remains after;
1- Card changed (very same type)
2- I've changed the REC-2 as wel as Rec5
3- I pull in 1-a and a directional contactor and motor operate fine, power section has been discarded.
4- voltage at TB-1 3.7 VCD, 2,3,4 36.5 VCD
5- Rec-1 tested and looks fine.
6- Cap. has been verified and operates well.

Any other sugestion to follow it up?

Regards,

Luis
