Many Thanks - I thoroughly recommend J J Cables - a very helpful guy - I was thinking about making all my cables myself, but after talking to the guy it just wasn't worth my time.
All cables ordered with confidence - thanks Ray T.

Thanks Julian, as I said I have measured them and quite confident of the lengths, I was just looking for re-assurance in case I have made a 'school boy' error with the routing etc.
I will probably get in touch with the 'cable guys' who attend Kempton Auto Jumble and ask there advice prior to ordering.
(anyone got a the phone number for the Cable Guys who attend Kempton AutoJumble?)
Again thanks Ray T

Twins / A65 - Ace Bars - cable lengths
« on: 05 June, 2017, 19:14:46 »
1966 A65 Lightning.
I’m fitting Ace Bars to a 1966 A65 Lightning.
I have early Amal 930 carbs with a twin cable twist throttle (no splitter, 2 cables required).
The clutch is early side entry to the clutch operating lever
The Choke operating lever is single cable, requiring a splitter for the other carb.
The Front brake is a full width hub (I know its the wrong one!).
Can someone please tell me the outer cable lengths for the following:
1)   The Throttle cable(s)
2)   The Choke cable (including the splitter box)
3)   The Clutch cable
4)   The Front Brake cable
I have measured the ‘cable runs’ but I would like confirmation/reassurance prior to ordering
Many thanks - Ray T.

I must admit this diagram is much simpler and easier to follow, my only problem is I have bought a new 1966 wiring diagram so really need to stick to original diagram as much as possible, but for clarity & understanding I can use this - many thanks - I also agree about 'forgeting the rectifier lead to light switch' as 'all'  output from the Alt. will be going straight to the new Reg/Rec box.- ray t

I now have another concern.....................please see attachment.
My concern is the output from the Alt. will be A.C. to the Rec. - from the left hand post of the REC., a wire pegs off and goes to 'post' no. 7 on the lighting switch, surely this 'current' will still be A.C.?
Anyone have an explanation ? - ray t

Just returned from Kempton - feet ache ! - Really good turn out with a fantastic Classic Bike Show under the main Grandstand.
Anyway, common sense finally took over and I decided NOT to buy a new Alt. (stator & rotor (the price alone made me reconsider)).
I spoke to Paul Goff (nice man - but quite expensive) who assured me a new Reg/Rec box was a good place to start and discard old Rec and Zenor Diode, Heat sink etc.(priced at £35 - could have got one for £28 elsewhere bit his advice/knowledge was worth the extra couple of quid).
I will setup with my 'old' Alt. (Stator & Rotor), wire in the new REG/REC box and cross my fingers - if its no good then a new Stator & Rotor will be purchased.
The new REG/REC box came with easy fitting instruction along with instruction regarding the 2/3 wire issue, which I now know to be a very simple fix, i.e.  join 2 of the wires together and feed reg/rec with just 2 wires. 
Just for info Stator £82.95, Rotor £84.95, REG/REC box £34.95 = £202.85

Again thanks for prompt response. So am I right in saying "single phase fully encapsulated alts. have 2 wires - my harness is expecting 3 - I guess it the wire to the lighting switch is the one we go without - is this correct? - ray t

Cheers guys - so pleased you are happy to share your knowledge - point taken regarding 3 phase Alternator and I'll be staying with the single phase option, as i plan NOT to fit either an electric start or extra spotlights (it did make me laugh! - its an old beezer for god sake!).
Also, Chris Goldby has been kind enough to email me, again in great depth, commenting especially on 'the 3rd wire' which caused me my original concerns. I have pasted it below as you just cant have enough info:
Hi Ray,
Ive been reading your posts on the forum and would like to get my twopennorth before you go and spend unnecessary amounts of cash at Kempton on Saturday.
Firstly, the alternator has nothing to do with being 6v or 12v. Its the power output that matters. All alternators had 3 wires up until about 1968, when Lucas used the zenor diode as the regulator.
The reason they were originally 3 wire was all the wires went to the switch, which acted as a 'regulator' when running day-time with no lights, it would allow power from one wire through to the rectifier. When you turned the pilot and rear lamp on, (running on sidelights) it would switch another one through, when you turned the headlight on all would be switched through.(each one is connected to 2 of the 6 coils in the alternator) This was to stop the battery boiling. When the Zenor, which is a regulator, came into use all three are connected and when the voltage gets to 14v, the Zenor kicks in and converts any extra to heat.
I have fitted many 3 wire into 2 wires in the wiring all you do is connect 2 of the three, colour immaterial, into one lead that goes to the rectifier, and the one left over, into the other rectifier lead. All the coils in the alternator then pump out all the power all the time, which is what you want. If you did what someone suggested and leave one of them out, you will only get 2/3 of the power which isnt enough.
Most spares suppliers do a Rectifier Regulator unit for about £30. Look on feked.com for their part ref fkreg123w. I have used a few of these and they do the job and last. If you use the £5 rectifier that you have bought, then they too are very reliable, although the terminals are a bit weak and when forcing the spade connector on they can snap off(dont ask how I know etc). However, you will then need to use a Zenor diode and heat sink to do the regulating.  A new Zenor can cost up to £30 and the Heatsink on top, makes the solid state one look far more economical.

I will study all the above, it all looks pretty straight forward - I do have a 'fully encapsulated' 6 coil Alt, complete with stator but I'm not sure of its condition, so I might just use what I've got and only buy new if needed - so I might wait for the next Kempton before spending hundreds of pounds.
Again many thanks for everyones input and I'm sure I now have enough info to take my project further - many thanks Ray T

As Saturday is looming fast, i will probably speak to Paul Goff. - At The moment I'm contemplating a 3 phase Alt, with an A REG 3 Rectifier/Regulator - cost is looking v. expensive though - £188 Alternator with Stator, Reg/rec another £40!. My only concern is the wire from the Reg/Rec unit back to the lighting switch - I'm sure he'll advise - ray t

Many thanks for the reply - I have attached a PDF of the wiring diagram I found and plan to follow.
I'm going to Kempton on Saturday and was going to bite the bullet and get new alternator & stator; as I have a new wiring diagram which expects 3 wire input I was going to opt for the 3 wire Alternator. As for the rectifier, I have purchased a £5 solid state of ebay, (seemed worth a punt at a fiver), which I have been told eliminates the zenner diode. (i do have the original rectifier and z/diode).
As I said before I'm note an electrician by any means so any advice is most welcome.

I think I found the answer a three phase alternator, but please correct me if I'm wrong - I'm certainly not 'lecky' minded!

Twins / A65 6v - 12v Alternator
« on: 13 May, 2017, 14:21:20 »
Hi, please help………….
I’m currently building an A65 Lightning to look something like a Clubman. I have a Lightning Clubman Headlight shell which has a Central Ammeter, the Key Switch left of centre and the Light Switch to the right. I have since bought the correct wiring harness and all looks good except……..the wiring harness appears (and also my wiring diagram) appears to be 6 volt.
You can tell this by the 3 wires present in the harness for the Alternator i.e.
1) Green/Yellow
2) Black/Green
3) White/Green
A 12v Alternator on has 2 wire output.
I planned to build the bike with 12v Electrics, having bought a 12v Boyer Ignition, 6v Coils & 12v Rectifier and now find my wiring diagram ‘not very useful’ as 12v Alternators only have 2 leads off of them.
Can you clever people out there please advise on this 6v / 12v alternator issue, better still recommend a 12v wiring diagram that includes the 2 headlight switches & ammeter, along with the 2 wire output from the alternator – many thanks Ray T.
