So i’m having some issues with both of my FOCBOX’s. I had a small spark inside my XT60 when plugging the FOCBOX to my battery, however all leads seem to be wired correctly and its a 42V 18650 battery pack that seems to be at an acceptable voltage. When i plug my battery in i get 5v out of all 5v pins but no lights and nothing out of the 3.3v pin. I had read that i can do a continuity check with my multimeter over the c25 capacitor to test if the 5v had been shorted to ground, which it appears it has.
Does this suggest theres an internal short over the CAN transceiver (u401)? And if so, Is there anything i can do to fix this, and can anyone suggest how this might have occurred? here are some photos of my setup…
