1934 car electronic

First -I do not have an old harness (all I have is six pieces of wire). I am happy to make my own loom for my car as it is rebuilt out of coloured wool that will be translated into coloured wire.

My questions are, does anyone have an original 1934 sports nine (4 seater)wiring diagram? What voltage regulator should I be using as opposed to what was in the car originally?

Thanks

You might want to look at Auto Sparks
http://www.autosparks.co.uk/product_inf ... ts_id=3656
This is for 1934 SLM at £252

The description states
Part # SR10c :
Harness Set to suit Nine Sports & Le Mans, 1934.
Horn Near Radiator
Braided Outer with Braided Cables.

They may be able to help for what you actually need.
Or what they make may be adaptable.

Thanks, yes I have been in contact with them and also other locals who have used their product. It appears the looms made here down under are vastly superior for about the same price. It was after having several discussions with them we reached the conclusion to do it the way I indicated. Unfortunately the local suppliers ( http://www.vinwire.com.au ) do not have a 1934 base diagram as a guide.

I will have to look, I know there is a diagram somewhere.

Can't find it...I know at one time it was on the web site...I found this ( http://www.singercars.com/restoration/w ... olors.html ) which wont help you very much but I will go through the backups and see if i can find the LM wiring diagram. I am guessing it got lost over the years as links changed.

I assume that you are discussing the wiring diagram which shows the voltage regulator conversion?

ThankYou Roly, that is the one I was thinking of. I know it was on the site at one time, now I feel bad for having lost it. But now that it is in the forum, it will stick around and be found in the future.

A while ago I harvested anything I could find about SLMs into a single file. I then kept adding any pics I came across from cars for sale. If anyone wants it here it is. It is 45mb as a PDF. As the word doc it's about 300mb! So be happy it's a PDF.

Thanks, the wiring diagram is exactly what I wanted.

So far I can't download the other file, I will try again later.

Nor me either!
I found a typo.
Try again.

I just checked it does work.

It's a bit slow at UK rural speed though!

downloads fine here at work (University with gigabit speeds

)

First 100 or so pages are right from this website and also my out-of-date personal site for my car, then all the good stuff. Pretty complete documentation on these cars.

By the way, good time to mention it...this forum is part of singercars.com but all of you do know that http://www.singercars.com has lots of information also right ? (I actually talked to a gentlemen 2 years ago who thought this forum was "the" website and didn't know about the actual site)

Hello
There was a link in this thread to a wiring diagram etc. that seems to have expired.
Does anyone know where I can get the diagram for a 1934 model year nine sports or similar.
It's the live feed through ignition switch / ammeter and to cut out CFR2 and three brush dynamo that I need.
Dynamo rebuilt and tests good at supplier but nothing on car. I think there is an 'historic' miss-wire that I've inherited!
Thanks
Neil

this was my mistake, when Roly posted the diagram I didn't notice it was a link to his website instead of a local file. I have e-mailed Roly asking for it and I will post it as a local file this time so it does not get lost again.

I don't know why it disappeared from my web site.....

I extracted the relevant part (from the 250 odd pages) and put it in place.

that was REALLY quick of Roly.

The wiring diagram above is on his site and so we don't lose it ever again, its here as a local file. Sorry for the duplicate but this way its here.

Thanks. Just what I need!
The reason I'm asking is very strange behavior of the charging circuit.
The car was off the road for over 30 years before I got it.
I had the dynamo - 3 brush - professionally rebuilt at a well renowned local specialist since it had lost a brush - shattered - and to avoid future problem.
When refitted it did not produce charge. I remove and took it for testing and it worked perfectly.
Fitted again and tried several ways of kick starting some charge at their suggestion.
I now have a dynamo / charge with the following symptoms;

Ign on - glow red and discharge about 2 Amps
Start and idle - no change
Increase revs and (especially if headlights on) the ign light goes out then as revs increase it comes on very bright!
Voltage on meter 45-50 measured on both dynamo connections.
No charge showing on ammeter.
If headlights on shows over 10A discharge.

I'm puzzled!
Thanks
Neil
