      Hi Joe,

      Your course access is still active, so all you have to do is log into your account and you can see the new units that were added to the course.

      Let me know if you have any other questions!

        Hi Rigo – it looks like you figured it out. You just needed to mark those new units as “completed”

          Sorry to hear that! I’m getting my notifications. Have you checked your spam folder?

            We’re happy to help. The techs I need to confer with are all on the road right now, but we’ll reply ASAP.

              In the first unit of the Motors module?

                I’m looking into this for you…

                  This was in the Core course, correct? No, you don’t need a reset. You already earned your Certification in that course.

                    Hi Davon,

                    Here are two quotes from the unit on Natural Gas:

                    1. When the gas reaches a customer’s meter, it passes through another regulator to reduce its pressure to under 7″ wc, if this is necessary.

                    2. Most household appliances that burn natural gas operate on 3 to 5″ WC pressure and have their own pressure regulator.

                    These are not talking about the same regulator. Quote 1 is referring to a regulator in the meter.

                    And here’s the quiz question:

                    Question #34 – Gas appliances that use natural gas have their own regulator which regulates the gas pressure to

                    So the quiz question is asking about the info in quote number 2.

                      Hi Davon,

                      Unfortunately this Forum software doesn’t make it easy to attach an image. Please email it to me (susan at mastersamuraitech.com) OR tell me the approximate time stamp in which particular video.

                        You’ll have access to your courses until your enrollment ends. It will only end in December if you don’t continue with the monthly subscription.

                        You can either update your payment method (at the bottom of your My Courses page) and just let the system bill you monthly, or if you would rather pay in blocks, then just get in touch with me in December and I can send you an invoice for how every many months you want to pay for.

                          As you’ve seen, we occasionally use a test as a learning tool itself, and not just testing exactly what we’ve already taught explicitly. This type of experience stretches a student and helps things to click more firmly after the struggle to figure it out.

                          As you go along, you’ll expand your schematic diagram “vocabulary” – in other words, recognizing what symbols and phrases mean.

                          Sometimes you just have to pore over the schematic, reading notes. For example…

                          Underneath the schematic they say, “Note – Bk(J) denotes black jumper wire on each radiant element between terminals 4 and S.”

                          So, that tells you what BK(J) is, and then you might notice that they indicate wire colors. For example, the LF burner that we focused on in this exercise has a Yellow wire to the left of the light. Up near H1 where the 3 jumpers come up, the 3rd notation says “Y+BK” which indicates where the LF light is tied in.

                          That H1 circuit is just shown once, but there would be 3 of those for the three single elements.

                          Then, the RF Blue wire comes in at the other Jumper, that is part of a dual-element burner. (You’ll see that over on the wiring diagram, too.)

                          Does that all make sense?

                          This is a diagram that takes some noodling over. We get asked about it a lot. But, it’s a great teaching tool!

                          Once you’ve completed the courses, you can continue getting exposure to schematics by watching our webinar recordings over at Appliantology!

                              Hi Davon,
                              They need an AC power source, not DC. Review the material in the Variable Frequency Drives unit if that doesn’t make sense.

                                That’s from whatever is beyond left field! I’d have to learn that stuff all over again. It’s been 35 years, give or take. Plus, there are places like Khan Academy that have lots of math instruction online.

                                  I ran this by the Samurai. He said that you sometimes have to wiggle the probes around to get good contact with the metal inside the slots of the receptacle. You should read near 120vac if you have one probe in the hot slot and one probe in the neutral slot (the longer slot).

                                  If you still are getting strangely low numbers, maybe someone could film you doing the measurements, showing the meter and its settings, and you could email that to me and we’ll take a look.
