Hi everybody I'm a new member saying hello and introducing myself.  I will be asking for a bit of help frome time to time.  I have a few bikes at the moment, 1973 T65 BSA/Triumph,  1951 Sunbeam S8, Greeves (unknown) work in progress,  1980ish Honda 250 RS, 1989 Suzuki DR750 Big, and my latest one is a 1984 Suzuki GS1100G.  I will post some photos later. 

The one I'm having bother with is the T65.  The wiring loom is totally knackered.  In fact it's been a pain ever since I got it and the previous owner never used it for years which is why it's only done 8000 miles.  I found a wiring diagram and was going to make one but thought new would be a better way to go.  The only way to do that is to find the part number of the wiring loom.  That is in a BSA book 00-5735 which has been out of print for 38 years.  Does anyone have a copy of this book.

OK I'll attempt to add a photo.  It was re-badged as a Triumph Trophy at the factory but they left the BSA badge on the timing cover.

The "BSA" T65 Thunderbolt was a Triumph TR6P (with the earlier front drum brake) badged as a BSA but built at Meriden as far as I'm aware, not a BSA badged as a Triumph.

Therefore you'd probably need to get a '73 TR6/TR7/T120/T140 wiring harness.

It isn't as simple as that.  The 1972 TR6R is the closest but that had the flat headlamp and slightly different hand controls (mine are Norton).  That had more room under the tank for some connections but mine has the coffin tank so no room.  Because it was made to empty the BSA store room of unwanted parts it's a real pain to get bits. 

This is what Classic bike had to say a few years ago.  Although my words were heavily edited in the article.

It's not a 1972 model, therefore the 1973 switchgear, headlamp and wiring harness is different to the 1972 model.

Looks like the same bike with a disc front brake.  Never seen one before.  See that's why I came here, thanks.

I suggest you try to find a back copy of the July 1986 edition of Classic Bike, as it contains a short article about the BSA T65 story "The Factory Tribsa".

I think I may have a copy in the loft.  Been a regular reader for too long.

This is what the problem is.  Most of the wires broke in the loom at the steering head.



And my assistant is useless. 

[L.A.B.]

Those wires look more like they've been cut?

However no wiring lasts forever, although it appears some owners obviously think it should because wiring is usually the last thing on the list to be replaced!

Of course you could always make your own harness?

[statik]

That's what I'll end up doing.  I have the diagram.



Just got to find the time.  The big Suzuki is at the front of the queue at the moment only needing minor cosmetic work and an oil change. 

[L.A.B.]

That's the wrong wiring diagram. That is for the 71-72 models with the 4 position ignition switch.

You need the diagram on pdf page 190 (Section H19, Fig. H14 Wiring diagram)

Dead right well spotted, that diagram came from Burton bike bits.  Good job I didn't order it. 

It seems I have been fed a lot of s**t for a long time about this bike.  Thanks again for the good advise.
