Tesla Gen3 charger modules wont communicate

Post by arber333 »

Hi Forum members

I recently got an EU Tesla Gen3 charger to torture. I followed the steps from Damien to light it up.
Then i butchered the control board contacts as per video... After i soldered wires correctly i tested connections by applying 12V and 5V to logic.
Next i connected 3V to enable and active lines on the boards AND i got CAN bus response.

However here is the problem... i only got CAN comms from the rightmost module. I only get two LEDs lit on the first module. Both other modules are silent with only enable LED lit.

I received next IDs from one module:
0x20B, 0x21B, 0x22B, 0x23B, 0x24B, 0x32B, 0x34B, 0x35B, 0x36B, 0x37B, 0x46B, x53B and 0x71B
I actually got that module to charge 3A to my battery.-

Can anyone comment why both other modules wont respond even though i bring them HV or AC?

tnx for your help
