20201220_ProjectShadow51.jpg

I was offered a Black Shadow project in 2013. I purchased the project and immediately started work on it.
Took the cylinders and heads to local Vincent machinist only 3 hrs away.
Crankshaft had been completed ,prior to my purchase, by a Canadian expert and also the tank was painted and done by "Bones".
Then, another Vincent project came up, Then a buddy stopped by and said" Go buy a BMW and lets travel the USA".
Then I got a wild hair and wanted to do the Trans America Trail (TAT). So I purchased a Husqvarna 701E and proceeded to farkle it out for the off road journey. So the Shadow was boxed up for another day.

All that behind, I am now focused on this Shadow project.
The pic above shows the big stuff with a thousand other pieces and projects in boxes.

My goal is a street friendly Black Shadow to ride on a semi daily basis, couple times a week.

I will stand corrected BUT

That is a H4 aka 'modern' sealed beam unit. I would be VERY surprised if it was an original Vincent works item. They all used 6V pre-focus bulbs.

Hi Marty, Please stand to be surprised, These Miller sealed beams were standard items on most, if not all USA sold Vincent, after Phil's visit to the USA and meeting with Indian Sales Company in about 1949.
H4 style bulbs were mandatory on all USA sold new 1940 automobiles , so as early as 1940 these bulbs were being manufactured and supplied.

I believe Indian and Harley Davidson had also complied with this USA sealed beam law in 1940 and because of Vincent being marketed thru Indian, the sealed beam compliance was passed on to USA Vincents.

The alignment glass tits on USA headlight bulbs came into law in 1957-58, two years after USA autos introduced 12volts as the new voltage standard. So titless headlight bulbs, now 2020, for restoration on pre 1958 are at a premium.

This change to sealed beam/no park light turned the Miller switch fourth position into instruments/taillight only. So Miller switch for headlight OFF-OFF-Headlight-OFF.

I also see the change in the handlebar dip switch from the outdated S157 baklite Miller dip switch to a more substantial Miller D/2 dip switch on the USA sealed beam head lamp harness. I believe this change for USA sold Vincents was a direct result of the Indian Sales Company meetings.

Received the wire supplies today, had the sheathing in stock.
Pulled the four wires thru the sheathing to get a start on the Shadow sealed beam wire harness or loom.
Keep an original harness near by for reference.
The speedo light wire is the original single wire out of the headlamp with a crudely spliced in pair of wires for lights.
I am still searching for a suitable triple cable to use for the dip switch.
.
The harness sheathing is British Wiring C712 by the meter.
The wire is Coventry Spares CS-5552 by the 10 foot lengths.

just as shown here, an 11" single wire leaves bucket (terminal #7) with 8" outside, then two wires (4" & 5") are spliced to the end with solder and wrapped with what appears to be heat shrink electric tape.

However i am looking at Chantland (original Black Shadow) photos and see two individual wires going back into the bucket.

What was the original dip switch wire like, I use old rubber 3 core flex, old pond pump cable is often a good source as it's very soft and obviously for outdoor use and not over thick wires.
The dip switch triple cable is very soft and flexible with about 0.270" OD and it is unlike a wrinkly vinyl sheath. Also dull finish like rubber, not shiny like vinyl,

Where do you find old pond pump cable? Please get me some details to allow purchase.

Ordered some special uninsulated ring terminals to suit me on this harness, to use in the headlamp bucket.

Not much progress, but did make up some tabs for ground and battery attach.

Craig, I have no idea where you would be able to buy the cable, I've cut mine off old failed pumps over the years, I will have a look what I have, measure some and if it looks suitable I will PM you and send some.

Fine multi stranded cable sheaved then connected to relays in the head lamp. Many years ago I bought a Britax did switch & horn button. Had no end of trouble with it as the contacts use to arc & burn up. When I understood what relays did I applied then and then with LED I used a lot of telephone wiring doubly sheaved but big wires for the main power supplies.

I’m told Rhode Island Wiring Service was given a NOS Miller loom to use as a pattern for making new sets. They list the dimmer part separately.

www.riwire.com

I had RIW duplicate the main harness as I had a NOS Miller wiring harness. As far as I know, Miller did not sell the dipswitch wiring with the harness. It was a separate item to be purchased. Thus, we had to guess about the dip switch harness, but it was consistent with the main harness.

The main harness replica is quite good with all the details done correctly to the original, except, RIW could not duplicate the odd-shaped ground tab. The wire lengths were copied from the original. They have a good inventory of vintage wiring supplies, but special items that have odd shapes were not produced by them. There were no PR38s in the harness kit.

The correct Miller sealed beam bulb connector is a Cole Hersee part with number No.3028 for a pair. Still found on eBay and elswhere. They do sell them pre wired, but if you want a heavier wire for 6V, you need the plain connector to allow your wire gauge choice.


20210213_ColeConn2.jpg20210213_ColeConn1.jpg

The connections do not require solder, simply strip back the insulation (about 1/2"), insert and peel back the wire over the metal and slide into slot. Be careful these metal inserts do not come back out with ease.

Looking foot rests and finding they are both off . They look okay on the bench, but mounted not so good .
What is the best method to straighten these?

KTB - heating to dull red and using moderate force.
Seems I always refer to KTB and find answer after asking dumb questions.
I don't keep KTB in the shop as I don't want to get it dirty!

Hi David, Are there any pictures of these wire harnesses please? Either NOS Miller or RIW ?
Thank you
Craig
