Reverse Polarity

This past week was alot of fun being able to use what i know and create a circuit that took alot of thinking, brainstorming, and testing. Using a switch, 2 relays, and a "door lock type motor" we were able to reverse polarity to get the motor to operate properly. We didint have a 2 way rocker switch so we ended up burning up a couple fuses in the process but were were able to find out just how to connect all of the components in correct sequence. Exciting...

DC Motor Video

Below is a video i found about DC motors that explained well how the brushed DC motor works.

One think I for some reason was confused with is the brushes. I wasnt aware polarity was changed as the rotor turned. It makes sense now...

Week 1

Getting back into class was pretty exciting for me after spending the summer learning about Anaerobic Digesters and working.

This week we dove back into electricity in a few different ways. I spent alot of time on the Truck Lightening system learn boards and was able to connect the lights in correct circuits to work. A few more things need to be connected to get it working fully which is something I will do in the following week.

I also spent some time creating a relay circuit with a bulb, 9V battery and test leads. Being able to create a circuit from scratch is something that seems somewhat basic but can really help in diagnosing or chasing down electrical problems. Trying not to get lost in the web of a wireing harness by getting back to the basics of a circuit will cut down on diagnosing time and frustration/confusion.

Run off the digester!

Transmission removal and clutch

This week we took the transmission off one I the floor display motors. We r/r the clutch and flywheel along with the pilot bearing. We also made needed inspection to the run out and play in the flywheel and housing.

Paying for my education!

Work today:
We switched things up from the trailer and continued working on the Vicwest panels. It's been months of work for the company (good news for me!) These panels are made to be a seamless wall... Finished product will be pretty sweet looking! Constructing involves bending the panels, cutting the extrusion to length, and aluminum welding. Hope it's counting for hours ;)

LAST 2 WEEKS

Having been very busy the past 2 weeks i have neglected to blog everything i have done. In class I have bee working on alighnments and as of recently looking to the stearing gear. I also did a flow test on the freightliner which i will put pictures up for.

I have been able to tie in some hours at work this weekend building a trap shooting trailer for a customer. It consisted of lots of different things. Sheet metal, welding, electrical, ect... PRETTY SWEET! I learned something somewhat valuable in building this trailer. WE have two 6 volt batteries we are going to run the thing off of rather then a 12 volt. For some reason its better because having two 6 volts, the batteries recover faster, stay maintained, and hold a charge better? or so i was told from a guy at the battery store.

hmmm...
