Title: My 'Home Made' Alternator Sub Harness - Sandcast /K0
Post by: ashimotok0 on January 07, 2011, 05:15:19 pm

Here is a link to a pic of my K0 'home made Alternator sub-harness, Can anyone tell me if the sleeving on the neutral switch looks correct for Sandcast/early K0. It's different to the Yamiya one but I reckon the Yamiya one is not faithful to the original. ChrisR kindly sent me a picture of a used early one. This has taken me almost a month of research to find the correct materials. I could not use the multi way connector supplied By Vintage Honda Connections because they were different to the originals, so I ultrasonically cleaned an old one which has not 'scrubbed up' too badly. His crimps supplied with the multi way were correct though and fitted perfectly into a genuine shell. the outer sheathing is rubber and the braided sleeving (two sizes) is silicone impregnated woven glass. The sleeving ends are covered with clear 3-1 ratio heatshrink tubing (tape on the original I think) and the neutral switch eyelet is covered in a Raychem heat shrinkable, adhesive lined  coupling sleeve.

Watch this space for a correct 'home made' replica braided battery earth lead. The Yamiya one is definitely incorrect and a very poor copy, in my view. The correct cable has soldered lugs and a braided outer - multi strand inner

This one looks correct though:

Ash
The harness looks great! Here's a shot of the harness from 576. Yours looks very close with the exception of the 576 harness having a spade type terminal on the neutral safety line.
