Had a little quality time with the machine again last night so I was able to finish up half the lights.
The process of wiring the harness is rather slow and to give you some insight in the process, here goes:
|1) Starting the process.|
I first start by going from the top-most (i.e closest to the player) hardware that needs wiring, and then roughly aligning the cable until it reaches the end of the board (i.e top of playfield).
I then fix the ends with cable clamps.
|2) Measuring and roughly estimating groups.|
Going from the bottom and up, I group hardware into sections to ease the actual routing of cables. In this case I was using flat-cables so I divided the cable in appropriate groups along the way.
Care is taken to not obstruct any hardware or hinder serviceability, while still maintaining slight esthetics.
This process alone took a good hour to complete.
|3) Cutting to length and fixing.|
Once that's done, I do another sweep and cut the cable groups in correct lengths and strip them, fasten and solder them in place.
There went 1.5-2 hours worth of time...
I also realized I completely missed the upper level lights so I had to route the cables for them as well. Luckily I had cables to spare (both lights and switches) so it was just a minute or two setback.
|4) Tidying up.|
Once everything is soldered, I sweep over the playfield once more to tidy things up. I believe I used 30-40 zip-ties for the left side alone during this session.
It's also during this I notice if anything needs to be changed to flow better, such as the cables around the servo on the bracket, for instance.
|5) Admire your hard work.|
The left side is now complete, with the exception of the flasher. I have not routed +12V on the playfield yet. It's routed to the playfield, just not around and on it.
The whole process took around 4 hours to complete, which is not bad considering I made the harness design on the fly.
I'll probably design it beforehand 'the next time (tm)'...
Having the hardware completed in the next couple of weeks seems entirely plausible now!
