The fan and the steering power is a result of the External BEC. It sounds like it's "dirty" power. The pulsing is probably coming from there.

You said the internal BEC would do nothing when the external BEC was removed. Hmmmmmm...........we need to get to the bottom of what's wrong with the internal BEC.

Had the red wire been removed or cut from the ESC plug that goes to the receiver?

If the internal BEC has not been disabled, then the internal BEC is dead.

This also means your MM Brain Board is running off the external BEC.

When you run an external BEC, you MUST disable the internal BEC by removing the red wire from the Receiver plug.

Otherwise, you have one BEC fighting against the other, especially when one's output voltage is different than the other.

Check the status of the red receiver wire for the internal BEC.

Let me know.
