Direct-Acting Solenoid Check Valve Animation

Here's the simplest way i can explain how a check valve works.Watch the switch close the circuit and operate the valve. I learned how pressure will activate the check valve in the system here.

Circuit boards 78 through 144 with weekly hours

Been working daily with the trusty Fluke multi-meter to determine faults in boards.

The most important thing I have learned is, no current flow no voltage drop, that applies to all these boards.

Basically I've learned a lot about shorts,h/r v/d's and open circuits.

What is a diode?

This is the video I think best describes a diode. It's simple way of explaining it helped me understand how they work. I learned that there are different sizes of diodes. And simply put its a one way valve for electricity.

Autoshop 101 Electrical Fundamentals Self Test

This was a small test that was about electrical current and flow. I got a few wrong but it let me see the correct answer so i was able to learn from my mistakes .

Circut Panels 1 through 77

There was lots of diagnosis that had to be done to get all these but i figured out how to use a light to find shorts and a multi meter to find open and h/r v/d ( high resistance voltage drop) panels. I thought this was going to be a lot harder than it was and i think i'm getting the hand of it .

Paccar Family Day

I took my family to the Paccar open house here's a few pictures from our fun day.

First day class assessment and circut panels 8 & 32

Basically was a questionnaire about where we stand in the class with what skill and knowledge we have so far .

Such as do we understand how to :

Read and interpret, electrical/electronic circuits using wiring diagrams.
Check applied voltages, circuit voltages, and voltage drops in electrical/electronic circuits using appropriate test equipment.
Check current flow in electrical/electronic circuits and components using digital multimeter or other appropriate test equipment. 
Check resistance in electrical/electronic circuits and components using appropriate test equipment.
Inspect and test fusible links, circuit breakers, relays, solenoids, and fuses; replace as needed. 

As well as others 


We checked circuit boards for faults and voltage draws
Learned how to use a multi meter and rule ot possibilities of where the draw comes from on different boards.I liked learning how to use this tool i know it will come in handy in my trade.
