I am trying to narrow down the cause of my broken vesc, version 4.10
I assumed it first stopped working after braking at slow speed after only being powered on for 1 minute. The motor just started twitching, and it refused to connect via usb, but it may have happened earlier and i hadn’t noticed.
I put it away for fews weeks came back It did briefly connect via USB. Whilst watching real time data, I ran motor detection, the motor twitched and i briefly saw the word ‘drv’ in the fault section, the vesc then disconnected and will no longer connect via USB. Now when powered on i just have a single solid blue light.
Motor confirmed fine as it operates perfectly with my other vesc. No visible damage Power to transmitter is normal at 5v Resistance between all motor wires on the good vesc is 82k. However, Resistance between red and yellow wires in bad vesc is 82k, but is only 36k between blue and the other two motor wires. Resistance from negative battery input to red yellow motor wires is 35k but only 1omh to the blue motor wire.
Does anyone know any other tests i can do to pin down the cause, before i blindly attempt to replace the drv.
