I have just completed my build and I am running a 6364 190 kv motor 12s1p 8ah set up. With a Maytech 4.12 VESC.(PPM) Every thing was running fine for the first twenty minutes. Then upon taking it to test. I rode it a few blocks to have it just die, and seemed to lose power. The RX was not lighting up while the VESC had a light on. So I walk home unplug it and try and sort it out. Only to get it working momentarily. Which point it stopped with some flashing red lights. So I unplugged it all, and let it sit. went to plug it in and nothing. no lights anywhere. And when I connect it to the battery I got a slight “ringing” noise. So I unpluged it and today I have it with my trying to sort the issue. So I connected it to the power and it worked okay. for a few minutes while I spun it up on the PC. 5 minutes tops and it just dies, no power, only fault I got in the tool was Status: Serial port error: The I/O operation has been aborted because of either a thread exit or an application request. Looking a the board it looks to be in fine condition. But I was hoping someone could help me work in the right direction, as I really don’t want to buy another VESC.
I don’t have an answer for you but I have read about running the motor without load on the workbench is not recommended because it can reach max erpm. Apprently, the vesc can be damaged if there is no set limit for max erpm.
I was barely running it up to 30% throttle. with out any load or weight on the board. But my issue seems to be power going through the board, as I had it working just fine, then all the lights went off, and it died. unplugged it for a bit, and it came back to life, only to die again, tried it again and it was alive shortly, but now I just get this humming like noise, and nothing. If I unplug the PPM the noise get louder. but no lights which makes me think there is a short somewhere on the board. which I am not able to determine.
Do you have an anit-spark switch in there? Maybe it’s faulty anti-spark?
I do not, I am getting 37 volts at the connection point to the VESC, just not getting any lights but a loud humming whistling noise that makes me believe something has blown on the board.
Is there any burnt smell coming from the vesc? Does the DRV chip look physically intact (e.g. no tiny pit holes on the chip, no charred marks on the pins, etc…)?
The only thing I can see on the DRV chip is what appears to be a finger print in some from of glue that was on it when they put it together. But I am not seeing anything burnt or smelling burnt, there as no pop noise, just running running, dead, complete lose of power, no lights just the noise.
So here is some pictures. But I get a ringing noise when I power it up. Like ding ding ding ding, etc very high pitch.
Got a charger on my batteries and got them back to full, and that seemed to get the VESC back on, but I ran it a little and got a few faults.

What did you set your battery max to on the esc? The battery leads look like they melted the solder on the vesc.
I have the max amps set to 40, with the max volts 57. The battery cutoff is at 30v absolute minimum 28volts. as I said not sure what issue if any I am experiencing as it seems to be in working order currently.
