Is my VESC toast? ABS Over current

ESK8 Electronics
#1

Edit: Caused by a poor bullet connector solder. Beneath the shrink wrap, one of the bullet connectors attached to the vesc must have become disconnected or had a poor connection. Eventually i pulled it off completely which revealed the issue

My vesc cannot do FOC or BDLC Motor detection. I have a 12S5P 30Q Battery with a 80A BMS Inside from eskating.eu. I cannot see any physical signs on the PCB that would indicate things have gone wrong, when comparing the VESC to a working 6.6 I have.

Vesc settings: MOTOR: http://prntscr.com/lef9nq

With no other vesc plugged in, motor detection will spin the motor for 1 microsecond and stop instantly, such that it makes a blip then spins off whatever speed it had. This is on a testbench with no belts on the motor at all. the vesc does this with both motors i have tested.

I think there is a chance that the phase wires may have touched during an earlier test. Could this fry the VESC? Is there anything I can do to have this repaired?

VESC Error: The following faults were registered since start:

Fault : FAULT_CODE_ABS_OVER_CURRENT Current : 34.7 Current filtered : 154.9 Voltage : 47.00 Duty : 0.011 RPM : 184.3 Tacho : 16 Cycles running : 6598 TIM duty : 554 TIM val samp : 277 TIM current samp : 24859 TIM top : 49165 Comm step : 1 Temperature : 28.40

Is produced by running a motor detection or pushing the trigger in any way on the testbench.

Yes, this can kill an esc. @Martinsp may be able to help

run it with no motor plugged in, if it faults then its definitely fried.

#6

No faults when pushing the trigger and running BDLC tests with no motors plugged in.

What was the outcome of this? I have exact same thing on one of my 4.12 maytech

Under one of my bullet connectors shrinkwraps, the connection had come off. Nearly completely so effectively it wasnt connected
