This looks like a very similar circuit to the one I am trying to
repair...

The component that has failed is one of those under the heatsink (far
left of the picture)....with the insulating pads underneath

Thanks

There is a very similar looking component right next to it, although it
has different markings.

The one I have removed was connected to the negative feed from the
battery, with one of the other pins connected to a resistor.

The other, similar one, has one pin connected to the positive battery
terminal (which is also shared with the positive feed to the motor),
and one of the other pins is connected to the negative feed to the
motor.


Sounds pretty likely, I'd expect there to be several MOSFETs in the
controller, is it in parallel with any other similar looking components?
