I was using my outlet tester around the house and came across an open ground in the outlet under the kitchen sink for the dishwasher/disposal. The top half of the receptacle is controlled by the switch for the disposal.
The only missing link in the ground path is a direct splice between the switch and receptacle although the switch and receptacle are grounded to the two respective boxes, which are connected by metal flex conduit. I know on paper the switch and receptacle should be directly connected, but shouldn't the way this is set up be providing a grounding path? Since my tester reads open ground my inclination is to just run a grounding wire between the two wire nuts (picture).
Here's a picture to make things clearer.
