SS650 Switches and Lghts

Posted by wilf_pyne at November 10. 2017

Ive just bought a 1967 SS650 which is in a pretty odd state. It has many  new parts

including a wiring loom which is not connected. It has a headlamp shell with

Ampmeter and a small hole, It has the metal Speedo / Revcounter bracket with instruments but no switches or lamps. could someone tell me what switches I

need, with Lucas? numbers, and what the three small holes are for (lamps I assume)

But what for and in what order.

Cheers Wilf.

Helo Now for your year these Norton 650ss had been upgraded to 12volts  so you need the SA88 lighting switch and a barrel switch for the ignition  best placed in the back of the tool tray  out of the way of eyesight the very small hole in the middle of headlamp is for a Lucas badge with its chrome bezel see Norton owners parts for these items  and you need to follow the Haynes Norton Twins wiring guide  for 12volt and coil ignition as the Atlas was   the same, as 650ss for the same year   , yours   Anna J Dixon

For what it's worth, I bought a 650ss brand new e reg early/mid 1967 and it was fitted with a k2fc magneto - my mate bought  an f reg atlas, which was fitted with the tin can type distributed, so both types were fitted in 1967

I didn't think that I was disputing that fact, merely pointing out that both ignition systems were used in 1967.

Hi Wilf,

If you wish to PM me I can send you the Norton spares book & the Lucas spares book to assist with your project.

In the lists, it shows your bike would have had the 5966A headlamp, which had the 36296A ammeter in the center, with one warning lamp to the right & one warning light to the left of the ammeter The hole below the ammeter was the 34289A light switch.

here are some pics of it:

Lucas Headlamp Assembly BSA/Triumph/Norton

Where it gets tough, is many of these numbers were updated over time, and different numbers are used now. As an example, the ammeter is now called a 36043 & is currently offered by Lucas.

 

The '67 650ss had a Lucas K2F magneto 42453A & the 650ss never had a distributor. In '67 the P11 was the only Norton twin with a dist., but in '68 the Atlas, P-11, and Commando came with distributors.

 

 

All the best,

Hi skip, you probably are right about the 650ss not having a distributor  in 1967, the dealer that I bought the bike off and proddy raced sold me a 650 engine from an insurance write off (I paid £25.00 for it t the time!) but that would be in 1970, so possibly from a mercury, but it did have a distributor fitted, which ended up on a racing outfit. I cannot remember the engine No.

My mates 1967 atlas (early f tag'd)  I am sure was fitted with a distributer which was changed for a mag when we both went proddy racing in 1968, (apparently developing a high rev misfire with the distributor).

Always good to get your constructive comments!

Terry

Just to be pedantic!, the only 650 to get a dissy was the early 650 std and 650 DL  which had the same as the 88/99DL. The twin points unit was fitted to the late Atlas ,Mercury etc fired twin coils so cannot be described as a dissy, We all know this of course but newcomers to the game may get confused.

Morning Robert, you are quite fight to point that out, I don't know the technical name for the coil ignition unit with twin point set up that I called a distributed! I am sure someone will enlighten me shortly!!

(I did have a 1960 99 which was originally fitted with the distributor)

Thanks. Terry

Hello All,  I think that I can offer a solution to this disagreement.  Some people call the points-holder on the later twins a distributor - when it clearly is not.  They call it this because, on the later 600/500 Dommies they did have a distributor - to distribute the spark from the single coil to each cylinder via a rotor arm in the distributor cap.  This distributor also held the single set of points and was 6 Volts.  The later system fitted on 12V 650s and Atlass (including Matchless/ AJS hybrids)  used a small alloy housing to s support a shaft running in proper ball bearings.  This housing held two sets of points to fire two coils and the advance/retard mechanism. So there was no need for a distributor.  People often replaced both systems with magnetos.  Usually because they had problems with the electrickery.  Cheers, Howard
