Fried Keya Motor, what happened?

Hello!
I have been running a Phidget 24v for a few months and now decided to upgrade to a Keya motor. I removed the 12v>24v converter and then removed the Cytron as well as reflashing the Teensy.

When I ran it for the first time it worked well but when I tried to grab the wheel to se if it would disengage with the “Current Turn Sensor” set to 39% the 10a fuse popped.

I replaced it and since then the Keya motor has not turned once. After trying everything I could think of I decided to open the Keya motor and this is what I saw:

I have checked the pins multiple times.
Pin1: 14v (tractor running)
Pin2: 0v (GND)
Pin3,4,5: 0V
Pin6: 2.7v
Pin7: 2.15v

The manuals tells me 10a fuse should not be too much. It’s also saying that it should be fitted with overcurrent and overvoltage protection.

Does anyone have an idea to what might have caused this? I’m thinking of ordering a new one or repairing this but it’s wasted if this happens again and I have no clue as to what caused it.

Have you posted this on the keya telegram chat.
Think there is someone from keya themselves regularly on there helping people

Exactly how did you wire it to the AIO board?

Pin 6 on the Keya to pin 16 on the ampseal and Pin 7 on the Keya to pin 17 on the ampseal.

Pin 1 has its own 12v power supply directly from the tractor and Pin 2 has its own GND as well. None of them are sharing wires with the AIO board.

If it happen the first day then I would say it’s a material defect. I guess Keya would replace it :thinking:

@Hammaren, did you end up finding out the cause of the burnout on your keya wheel?
