Test for Power. Remove the screws on the switch cover plate, and pull off the cover plate to expose the switch wiring. Without touching any wires, test each wire in the electrical box with a non-contact voltage tester. Also, test each of the side terminals on the switch by touching it with the tip of the tester.
Step 1: Locate the fuse in the box, usually found under the hood. Step 2: Grounding the test light correctly. Step 3: Connecting the test light’s probe to a positive power source. Step 4: Ensure that your test light is functioning as it should. Step 5: And finally, the actual testing of the fuses. We will delve into each of these steps in Ray-triangle intersection. Condition 1: point is on ray. Condition 2: point is on plane. Condition 3: point is on the inside of all three edges. First solve 1&2 (ray–plane intersection) substitute and solve for t: Ray-triangle intersection. • In plane, triangle is the intersection of 3 half spaces.
