'54 C11G WIRE HARNESS
« on: November 04, 2020, 01:11:35 am »
Hello Folks -

Although I haven't yet started working on my (new to me) C11G, I am slowly familiarizing myself with it.  I had said that I was going to post a bunch of pictures and have you all point out what you could see... the bad and the good.  And I still plan on doing that.
But for now, I did jump my planned start just a bit.
The wiring harness has had quite a bit of amateurish dabbling through the years.
While poking around on eBay tonight, I found this replica wiring harness.

https://www.ebay.com/itm/new-WIRING-HARNESS-LOOM-for-BSA-C11G-alternator-coil-ignition-models-1954-56/124362407920?hash=item1cf493bff0:g:kZkAAOxyxU1Q8G6l

It clearly claims to be the correct harness for a 1954 C11G.  It also references the harness as being a replica of part # 82 and goes on to say that the buyer should verify the part # against the BSA Spare Parts Book.
Here's my dilemma (beyond the mess of wiring in the picture).  There's no wiring harness shown as a specific part in any of the schematics in my Spare Parts book.  Reading through the parts # listings doesn't show a part # 82 either.
So I need some guidance.  If I'm ever to see if this bike will ever start I'm going to have to establish spark and thus wanting proper wiring before moving on to the next thing.
Is this harness correct?  Are any of you familiar with the seller?  Should I pass and seek out an NOS OEM harness?
Thoughts would be appreciated.

Pete

That is a new replica harness, Pete, because of its terminals and shiny sheathing, so we have no way of knowing if it's correct or what it's intended for.

For about the same money, Draganfly can supply a C11G loom, they show to have plenty in stock, and these look more original, with their cotton-braided covering. I bought an old C11G several years ago and this came with a new Dragonfly loom, receipt included, that the previous owner had never fitted, although he'd removed a lot of the old one. This new loom fitted perfectly and was never any problem. The bike was left on the original, 6v electrical system but had a just new, solid state rectifier.

It's easy to check for a spark by connecting a slave battery direct to the coil live side, temporary low tension wire from coil to points and condenser and an earth wire to bike frame or engine. You don't need the loom or switch gear.

Good Advice Ray
Thank you.  Exactly what I was hoping for.
I agree that I can run temporary jumper wires to see if I can get a spark.  And when ready, I'll be posting.
The reason I zeroed in on this harness is b/c I knew I was going to need one and wasn't sure how difficult they'd be to get if I waited.
I'd much rather have one that is known to other collectors and is proven to closely match the original.
That said, can you provide me with the contact information for Dragonfly?  I'm assuming Dragonfly is a business whereas you said they have plenty in stock.  If it's an item they'll continue to be making/stocking I'll simply add the contact info. to my ever growing list of sources/vendors. If they're not going to be continuing with stocking them I won't wait - I'll purchase now even though I won't need it for quite awhile.

Dearer than one on ebay , but much more original and likely to be correct.

Thanks guys!
Much better than the one I had come across on eBay.
Appears to be a regularly stocked item so I'll add Draganfly to my list of sources for a future purchase.
In the interim. I'll pickup an inexpensive 6V battery so I can see if I can get spark.
I'll post about it/ask questions when I do.
Thanks again!!!

It's the same price within a very few pence, Graham, without the vat. I thought, maybe, vat wouldn't be charged if it's for somewhere other than the UK, or an EEC country at this very moment in time.

I know there's p & p on it and the other loom says carriage is free but I'd be surprised if they'd send it over the North Pole for nothing.

£17.95 carriage for the one on ebay, Draganfly dont give carraige price until you go through checkout and enter delivery address....probably be about the same :-\ Don't know which one will end up being cheapest, but the Draganfly one certainly looks more original.

 I wasn't expecting free postage to the US.  I also didn't pay much attention to any price difference.  The eBay one I had asked about converted pricing into American dollars.  The Draganfly reads
"£ 67.14 (£ 55.95 excl VAT) each"   ???   I stopped there.  If this were one of my clues that I needed to decipher in order to get out of an escape room I'd die in the room!  LOL
Whatever the cost ends up being I'll just be glad to have a properly fitting and looking harness.
Kidding aside, at a glance I'd guesstimate this to be roughly $90 American plus maybe another $20 - $30 shipping.
It does look as if I need to purchase additional end connectors, insulators, etc.  I'll sort that out prior to purchasing.

I'm pretty sure your chances of getting a good quality and accurate loom will be higher from Draganfly.
Most goods and services in the UK have 20% value added tax paid by the end consumer.
If you are vat "registered" business like a garage for example, then you would end up paying the pre vat prices for all materials used.
I hope the gets you out of the room Pete :D
