S1 Indicators
#21
Alan,
Looking at your picture, you seem to have something very similar to an MG midget indicator switch. These are available new for about ?25, however as with everything E type, a very similar component that is unique to the E, retails for anything between ?150 and ?200. This MAY explain why yours has the switch it has, though others might shed more light on it for you. I did a lot of research into these switches. Some of the Mk2 parts are interchangeable and much more conservatively priced.

Alan,
As I believe I mentioned before, both the C25254 and C25256 I obtained from Barratt have the metal fingers. On the C25256, the white plastic canceling ring is integral with the unit, which encircles the steering column, unlike the C25254. With the C25254, it must be a separate part, so you should ask Barratt about that.
Best regards,
Day

The car in question is a 1962 OTS if I read things correctly?
The part you need is Lucas #34361/A-37SA; Jaguar #C16069:


The 4.2 cars used Lucas #34791/D-85A.SA; Jaguar #C25254


With the introduction of the collapsible steering column Jaguar used Lucas #35531/B-131SA which is the one that uses the white nylon striker ring #11316.


These screen captures are from the 1962, 1965 and 1968 Lucas Jaguar catalogues. These along with the 1948 to 1962 and 1973 Lucas catalogues are available for download in the Forum KB.
So #C25256 is for the collapsible steering column with integrated cancelling ring, #C25254 is for the non collapsible column and uses the metal 'finger' for cancelling.
Original 3.8 indicator switch #C16069 supersedes to #C21710 and still available
Original 4.2 indicator switch #C25254 is still available
Original 4.2 collapsible column indicator switch #C25256 is still available
For the S1.5 and S2 cars with integral horn - Lucas #35876; Jaguar #C28489

Thanks for the clarification.
So I've ordered C25254, the later 4,2 version which to my mind is superior in operation to the earlier "plastic" unit I currently have.
It might not be for the purists but I'd rather have reliable self cancelling indicators than end up in danger of having an accident.
Thanks for bearing with me on this.
Cheers

Very interesting materials, David. My 67 OTS has the C25256 and a non-collapsible column, although it is certainly possible it is a replacement. So, if I'm understanding this correctly, for Alan's benefit, the part number C16451, number 30 in the diagram you posted, David, actually cancels unit C25254, without a plastic ring. For unit C25256, as on my car, part C16451 is simply what holds the white plastic ring in place and the white plastic ring turns with the inner column and contacts the metal diamond shaped pieces on the controller which cancels the unit. So, hopefully either C25254 or C25256, which is supposedly a design improvement on C25254, will fit Alan's car if his column looks like the one in David's diagram and has the C16451. Both C25254 and C25256, with metal canceling mechanisms, should be an improvement on the "plastic unit."

The S3 parts catalogue probably shows it best:

S2 = #C28489
S3 = #C33503 (different connectors)
In Alan's case I would recommend he buys the original 3.8 indicator switch #C16069 which now supersedes to #C21710. Somewhere at the back of my mind I seem to remember fitting later switches to early cars causes problems with the cowl. Worth checking parts numbers are all the same.

I've now received the self cancelling unit and you're right the terminals do end up hard against the rear of the cowl. But the original plastic unit does exactly the same. I'd forgotten that when I fitted it I had to line the cowl with insulating tape to prevent a short occurring.
I'm assuming that this wasn't the case when the car left the factory and it's only because I'm now using repro items that this is occurring.

Interesting. Having just joined the forum and new ser1 owner, my indicators do not self return .un knowingly I thought that was the way they are.
Little job to do over the winter now
A bit to learn !

Interestingly enough, my 65 coupe with thought to be very original from a mechanical perspective, cancels in one direction but not the other. Ane the direction it cancels in, must be subjected to a very tight turn or it doesn't cancel either.
Should I even bother? I've gotten sort of used to me canceling when necessary!

#30 Re: S1 Indicators
I am just trying to improve the operation of the indicators on S1 March 1966 car.
The issues are - wobbly indicator stalk in all directions and also LH turn indicator does not always engage and hold with steering wheel straight ahead.
Reading this thread shows me I have the later #35531/B-131SA unit not the 85SA unit as is quoted for a 4.2. This is similar to Day because the car does not have a collapsible column. Again my unit looks very original with a the stalk chrome quite pitted with rust.
Regarding the wobbly stalk, could anyone suggest if there is a way to 'tighten' it up. Here is a picture which shows a small threaded rod which seems to go through into the nylon where the stalk is located (however is does not seem to be a grub screw). I wondered if that was anything to do with it?

Regarding the the LH turn not 'holding' it is clear this is because the cancelling ring is not in the correct position relative to the teardrop pieces. You can just make out the lug on the ring which does the cancelling and it ought to be central between the two teardrops.
How can the ring be adjusted to make it correct, or is it because the steering column is not correctly centralised?

Any advice would be welcome.
Thanks
Steve

#31 Re: S1 Indicators
Day Krolik,
I just finished replacing the steering column bushings on my car (400 cars earlier than yours, 1E14988!) and while doing so, found the reason that my left turn cancelling never worked from the time that I bought the car in 2008. It turned out that one of the lugs on the cancelling ring was broken and by rotating the ring 180 degrees upon reassembly, it now works as it should. I understand that Marek is making a (upgraded?) replacement ring for at least the Series 1 cars. Maybe he will chime in?
