Vital Signs

As of today, the major electrical work on the Davenport is finished.

This tiny locomotive now sports 12 NiCd batteries, an ELITE throttle by RCS, and a Phoenix P5 sound system, as well as a P5T interface board, and all of the requisite wiring to make them all work, under the tiny hood.

The power switch is under the rear frame of the locomotive, as is the radio receiver. The small speaker will fit in front, between the frames. The charging jack will go in the rear cab wall, and be disguised by a sand box / cab seat on the inside, and either a sand fill or a handbrake on the outside. I'll go more into the cosmetic details next time, when I have photos to show how they're progressing... the big news TODAY is that other than connecting the headlights, the electrical work on this locomotive is FINISHED!

The first trial fitting of the various components was not especially encouraging (and, I'm told led to indigestion in some quarters!) There seemed to be no way to fit everything in ... and more wire than a local telephone exchange!



I found the best way to overcome the "octopus" the project seemed to be swallowed by was to remove all of the extra wires from the Phoenix and P5T ... there are several extra wires pinned into the plugs that aren't needed for what I'm doing here. I also shortened up harnesses where possible, and then connected what was left in neat, organized bundles. With the battery pack modified from its standard 4-4-4 arrangement to a top row of 4, a middle row of 5, and a bottom row of 3 cells, I found I had room for all of the electronics on top (including the Phoenix P5 at the extreme rear of the hood, vertically,) and sufficient clearance for the worm and gears underneath. With the battery secured to the right hand side of the hood, there was a space along the left that accomodated the P5T, and all of the bundled wires, as well as the volume switch. With the "Octopus" gone, everything finally fit in a functional, if crowded, way.



Much better! The programming port can be removed by unplugging it from the board once the board has been programmed ... which I did (though not before taking the photo above, apparently.) All that was left was a full scale test ... and I'm happy to report everything started up and ran like a charm... both sound and motor. The speaker in the above photo is a full size Phoenix speaker, and I used it just for testing -- the actual speaker is much smaller and will fit between the front frames, and ahead of the power block.

Now to finish up, there's still lots of cosmetic work to do, as well as final re-assembly, and cleaning up all the debris and marks that a major surgery like this always leaves ...

But today, it's alive! ALLLIIIIVE!
