I have two new VESCs from DIY.
I set them both up via the BLDC tool.
One was fully connected to the motor, battery, and transmitter. It was working fine when tested.
Next, I connected the 2nd VESC via the XT90 parallel connector. At that point, both VESCs stopped working.
The lights now no longer go on for both VESCs. They don’t connect to the BLDC tool.
My battery is a 8s.
It check the wiring. It doesn’t seem to be reverse polarity since one VESC was working.
Any thoughts on what I should do now? If I buy new ones, I don’t want the same thing to happen.
Or maybe there is a simple repair.
I would appreciate any advice.
