This week we went deeper into diodes. We started exploring how a diode work and why it only travels in one direction. I have learned a lot on how the diode works internally and that has helped me to better understand what happens when they fail. Here is a video that helped me understand diodes.

This week I started back in class at school. I have started to learn about fuel injection pumps. I took apart a Bosch single-plunger fuel injection pump. I learned how simple these pumps can be and the many different types of pumps.
This week I learned about the pins that allow you to tilt the bucket on a Bobcat. The pins on the Bobcat are tapered. You fill behind it with grease and then pull tight with the bolt and that's what it pivots on.
