It fixed the issue. I think it was the solder joints of the Bullet connectors and the massive wires out of the NEU.
I did try the previous failed MMM and it is still not responding.

I think the issue is that lead free solder that just needs so much heat to flow.

Thanks to all of you guys that chimed in.

Did you re-solder the castle pre-assembled bullets also?

I read in another thread a guy who had a cold solder joint on one of the castle fitted 6.5mm male bullets.
Just wondering if faulty solder joints are to blame for some of the MMM failures?

Cold solder joint on the motor side causing the speed control to over heat and letting the smoke out??

Cold solder joint on battery side causing some BEC issues???

I know it wouldn't explain all failures but could it be contributing???
