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.
