triumphs

[L.A.B.]

hi guys thanks for the response, I have found the engine number prefix "5TA" then the H20809 so that makes the original bike a 'Speed Twin" is that correct?

Yes, that should make it a Speed Twin.

there are three wires coming out the bottom of the engine, seems to be located between gearbox and clutch housing these I assume to be from the alternator,

Very likely, what are the colours of those wires?

they would go to the rectifier/regulator unit hey can anyone tell me which terminals the wires connect to, I assume two would be the ac input to the rectifier but the third I don't know, but there again am I correct about two being the rectifier ac input?

There should be a rectifier, and two alternator wires go to it, assuming the three wires you have found are light Green, mid Green and dark Green?

The light and dark green wires can connect to either one of the rectifier outer terminals (3 terminals?).

However, this is where it gets a little complicated, as those early 6V alternator systems used the ignition and lighting switches to regulate output, by switching in the extra alternator (mid Green) wire for lighting, which according to the wiring diagram I have, mid Green goes to terminal 16 of the PRS8 combined ignition & lighting switch.

is there a "best' workshop manual for this model  triumph, I just don't want to buy one and find I could have got better when I'm so far away from the UK
thanks and cheers everyone I'll be waiting!!  

I  couldn't really say for sure if one would be better for you than another? As they all seem to leave out some pretty vital pieces of information at times!

Maybe the Haynes would be the better option for you as they show things step-by-step with photos (sometimes not very good photos) although the Haynes manuals often try to cover too many model types in the same book, which can sometimes be confusing.

The original factory manuals were really meant as reference books for motorcycle dealer workshops, rather than to be used private owners, as is more common these days, so tend to be written in a way that assumes the person reading it has had a certain amount of experience and training.

There's also the American Clymer manuals, and these are normally very good for the enthusiast.
The particular manual you require covers many different models of British bikes, and I have no idea how much of that manual space is devoted to the 5TA model. And it's really meant for 63-on unit 500 models.

However the Owners' Instruction Manuals of that period are somewhat of a mini-manual in themselves, so can be useful.

The Haynes manuals are pretty good for wiring diagrams etc. although if the bike is to be ridden regularly it may be a good move to uprate the electrics to 12volt and perhaps (dare I say it?) electronic ignition.

can anyone please help me with the 1961 engine triumph alternator output wiring identification, 3 wires exiting engine where/to what terminals on rectify/regulator do I conect them do I need to identify each wire? is the unit three or single phase thanks

can anyone please help me with the 1961 engine triumph alternator output wiring identification,

I have already given that information? If what you have doesn't match that, then please could you say why it doesn't match?

3 wires exiting engine where/to what terminals on rectify/regulator do I conect them do I need to identify each wire?

Again, I have already given that information? If you've found something is different then please can you say why it is different? Yes, you do need to identify each wire.

is the unit three or single phase thanks

The original 1961 alternator would have been single phase, with two output wires going to the rectifier and a third separate output wire going to the ignition/lighting switch.
There were no actual three-phase Lucas alternators until 1976 (RM24).
Just because there are three wires that doesn't necessarily make it three phase.

However it must be understood that anything on that particular machine could have been changed over the last 47 years.

Beesa, I think you really need to get a manual. Your questions would be answerable instantly if you had the info in front of you.

hi everybody

anyone help me with this problem or give me some pointers please
Triumph Trident 1969 engine number:- C02753t150t

when it was running centre cylinder exhaust pipe was cool to cold, left unit not too hot right extremely hot, the bike was then given to 'someone' for service work including tappet adjustment, oil/filter change, carbs cleaned and I think an attempt at checking the timing was carried out (not too sure there) anyway the bike refuses to start now and I've been asked to look at it (for a friend)

can anyone give me a few pointers, as I've said before I'm an enthusiast with a mechanical background, but nothing about tridents, twins ok tridents zero

thanks everybody

regards sidecar

Sorry, but from what you said, I'm not sure if you've actually looked at the bike yet, as you said you have been "asked to look at it", so may not have actually done so yet? Were those symptoms described to you, or did you mean that you have actually looked at it?

It's a bit difficult to say what the problem (or problems) could be, other than it could be either an ignition, carbs or engine problem?

I can only suggest that you have a look at it and check the normal things like plugs, ignition timing, tappet adjustment and carbs etc.?

And then come back here once you have more of a rough idea what the problem could possibly be, or at least be able to tell us what things you have found it not to be? And what modifications have been made, for instance, has an electronic ignition system been fitted (if so, what type?) etc..

  

[beesa]

thanks L.A.B.
as you wrote, the symptoms have only been described to me and I have not seen the bike yet, the bike should be with me tomorrow then I will be able to get a look at it.
I will check out the items you have suggested then come back to you, thanks for those pointers
Will be back in touch as soon as I can

Beesa, maybe I can help with electric diagrams, done a A65T OIF while ago, very similar. Curently buzy with a Triumph T110 pre-unit. Regards, Barend

[beesa]

hey Barend

thanks for the message, any information on the "OIF" models would be much appreciated, wiring diagrams especially, do you have any pictures/photos of the bike in it's original form, the one I have is in several cardboard boxes at the moment, but here's the engine  and model number HG 60917 T120 5 speed

regards beesa

Hi Beesa,

I did a rebuild of the '71 A65T, started with no knowledge of British bikes, previously only done Japanese. Usefull was a parts manual for the bike, and a Haynes workshop manual. Build up a library of pictures from bikes that gets advertised on e-bay, normally the seller would place a number of photos from different angles, became very usefull in getting detail during the rebuild. Drop me an e-mail at barendj@lantic.net, based in Richards Bay, South Africa. Regards, Barend
