A Blown motivator????

This is'nt to do with R2 but I went to pick up Skye from school in her Toylander, no problems. Then on the way home we went to go gently up a kerb and - no power and a electrical burning smell. That was it power off push up the kerb and see if it would reset.
No such luck so lift the back by the rear suspension and a 600m carry home!!

Closer inspection reveals this -




Spot the burnt out resistors!!!! - 3rd repair job on this motor controller.
