Happy to help, Neal!
Let’s start with question 6:
Which timer cam and contacts must be made for the washer motor to run in high speed mode?
You have to read the timer chart to find the answer to this question — if you’re not totally sure how to do that, you’ll want to review the videos in the previous two units. Both of those gave examples of using timer charts for troubleshooting.
If you want even more of a review on timing charts, you can check out the video in module 5, unit 5 of Fundamentals.
If you’re still not clear on how to answer this question after reviewing those videos, let me know exactly what’s confusing you, and I’ll clarify it best I can.
