earth cable

[Graeme77]

This is my wiring so far.
I would have put pics up earlier but there is a size limit and ive only just worked out how to change size.

From that photo the rectifier loom plug does seem to have a green... confused.

Just found this pic for the K series... luckily my earth strap correct. Wouldn't have thought the F would be different.

I appreciate the following is not a lot of help.... I was looking through the F1 difference wrt your rectifier earthing... but it's says nothing... implying the set up is the same???

Anyways,

Still confused Graeme.

In your photo you've the fuse holder connector lowermost, and above it the rectifier connector. In the wiring diagram (my last post) these two connectors are reversed, ie the rectifier is lowermost. And it has a green wire.... (+ 3x Yellow + Red/White) which presumably is connecting into the bikes loom, and thence an earthing point somewhere?

At the mo can't think of what your spare 5" heavy duty cable might be, but by the eyelet sizes am wondering whether the PO connected the battery earth to a nearer point on the frame rather than the standard engine hanger bolt?

...just checked the DSS website... His reg / rectifier is a combined aftermarket part... same # for both 750 K & F series. Notably this part has the standard loom connector with included green earth wire.

So, I'm confused... and will have to bow out on this one!

Oh... that 5" strap??? its shape looks awfully like it connected the batt -ve to the forward most R battery cradle mount in your pic!

Battery to battery box mount is what I thought. My main earth is good though so ill leave the extra one out.
that drawing helps too. Ive put the multi connectors in the wrong holders. They fell easier that way as I ran the wiring behind the fuse box.
Its not right, but neat enough and should all work.
Thanks for the help

Here is my F1, used a star washer on rectifier mount plus extra earth

Where did you run the extra earth to? Was there a problem before you did this?

The extra earth runs to negative on battery and another extra earth to one by coil mounting.

Its covered with black sheath and crimped non insulated 6mm ring terminals with a piece of heat shrink to tidy up, so is unobtrusive.

My concern was to make sure the rubber mounted battery/rectifier bracket was fully earthed.

Mainly a precaution based on previouse experience of earthing problems, which can be a pain.

The black and white photo, Simon posted, shows the bare braided K0  earth cable. These are mega rare now NOS and the Yamiya repro, although cheap enough is sh*te. Second hand ones are always tarnished or totally sha**ed.  I have done an 'anatomy' of the original (hundreds of tiny tinned copper wires inside a braided tinned copper sheath) and I am having some brass, then tin plated,  terminals laser cut to make a  proper repro of this part. Will be a few weeks yet before I have a sample. The later cables are made from the typical PVC sleeved, high current,  cable, common to earlier Hondas. I have made a test setup to check the integrity of the soldering of the hundreds of wire cores. This consists of passing a calibrated  100A DC pulse down the finished cable and measuring the voltage drop (mV).

...put me down for one Ash... funds up front if you want 'em.

Yep me too Ash...
