Day One:

Absent.

Day Two:

Absent.

Day Three:

The next step of the project was to do the ground wires. with the new design, the whole charging system has a common ground. There were a couple of options for how to do this. A fastener and lug nut could be used like they were for the power wires, but this would be quite tricky and impractical since there are eight or so wires that need to be connected. As mentioned previously, another option would be an aluminum grounding strip, but since this strip would be mounted to an aluminum frame, the frame itself would become the ground which, when using DC is not a great idea. Therefore, if I wanted to use a grounding strip, I would have to figure out a way to insulate the aluminum strip from whatever I mount it to on the project. In the end, it was decided that I would connect all the ground wires to the ground ports of the fuse block. I also worked some more today and organizing the wires and I used some cable ties to move the monitor cables to the side of the project so they were not dangling down over everything.

Day Four:

I continue to clean up the wires on the project. I removed the old wires that went to the amp since they do not do anything anymore. Mr. Harlow says that I had the right idea with the cable tie I used previously, but that I should switch it out for one that screws on instead of using adhesive. I worked some more on the grounding wires. I connected the wires from the fuse blocks to the grounding wires on the charger. Then I started working on the wires that will go between the grounds of the battery and the fuse blocks. These wires take some time because the metal piece that goes into the connector needs to be soldered on as opposed to crimping.

Day Five:

As of the end of today, I have completed and installed six of the eight ground wires. I also removed the old wires that went to the amp which did not do anything. I spent some more time organizing the wires and discussed with Mr. Harlow the idea of making acrylic plates to mount things on that would make the wiring more organized and look nicer. Once I finish the next two ground wires, I will be done with the wiring for the battery charging system. A lot of testing and checking will still need to be done before the new batteries are actually installed. I (as well as Mr. Harlow for some parts) recheck the schematic, check that my wiring matches the schematic, and then use a multimeter to perform continuity tests to make sure all of the connections and all of the wires actually work.
