Re-Engineer your Iman: January 2010

The wiring project

Posted by Ma Zul at 7:25 AM

Last Thursday, 14 Jan, we have been delivered new task to be done in lab. The task is simple. Cut the wire insulator, crimping the other parts of the wire, twisted the wire, soldered it, cover that area with the tube insulator and shrink it with heater. But all the task must be done surely by follow the labsheet that have been given to us. Here is how we do it...

Both wire are twisted. Surely have to make it tight and grip well

Soldered onto its surface. To make this perfectly, one must heat the wire first and then soldered it.

The solder wire connection covered with shrinking tube. Then exposed onto the heater gun so that the shrinking tube shrink and grip nicely.

Where my skill is being tested..

Last week till Wednesday this week, we have workout on electrical lab. Our job is to reconstruct back the electrical panel, which has been abandoned for almost 20 years. This is what En. Zul told us. Likely to say, this job is really tough. Even though it is under my expertise in solving of the electronic equipment and troubleshooting, but this one needs the board become tidiness, good arrangement on wires, label on each wires and lacing the group of wires. This surely makes me become uneasy to tackle the time.

The board, shape as control box , have 4 panels. Each of them consists of navigation light, strobe light, DPDT switch,master switch, solenoid and circuit breaker. At first look, it's an easy task. We just placing the wire on the circuit board by followed the instruction on the lab sheet. But things sometimes worse when some of the wires ( which we have to, recycled it back from the trash- I mean still can be used) does not long enough to connect the circuit board. Surely, we have to find other wire, crimping it and placing onto the circuit. Furthermore, we have to figure out on how to make lacing with the wire applied on board. By this week, the problem solved.

Our next step is to make the functional test. The only reason is testing whether the circuit is functioning or vice versa. During the functional test, my circuit board doesn't functional as it should be. Why is that? I figured out and find that problem comes from the wire jumper that is not properly connected( wire does worn out), Emm...maybe I should care enough on this, especially when have the electrical repairing on aircraft next time.

The board that has been leftover for 20 yeras! All wiring is still can be used. That is why we recycled it back. surely, we have to check the wire connection first.

Re-construct back the circuit board.

Control box. Each panel for a person.

Done new connection,added by me!

When switch all the DPDT switch, all Nav light, Fan, strobe light will goes 'ON' state. When the push button press, the solenoid moves upward and backward.

Alhamdulillah, a lot of tools we know there...

On 4thJanuary 2010 4.30pm, Azlan, Amar and Ramzi and I had gone into the Tools Store, that situated in front of our class. Actually, the student are not allowed to enter the tools store. Student just allowed to ask and get their tools only. So, What we were doing there? Have talk over the staff in there? Well, I probably say no.

Actually, we were doing some helping hand for the staff in that tools store by bring the tools items that have been return by the students back into its toolbox , shelves and other compartments. Most of the items are screw drivers, wrench set, protector, tap and die set and various types of air tube,

Were we doing this just for fun?

No. We went there because we want to learn many basic tools that have been preserve for mechanical use. Also we, the fresh EASA students program doesn't know much about that item. So we take this advantage by learning as much as we can.

Maybe you will think that we work there under the circumstances. Yeah. That's right! And thanks to En Zul, the coordinator of EASA program, because he challenge us to work within that tools store. Without his challenge, maybe we were not able to get there..and find out the right tools to use on aircraft. Hehe....
