Graeme Robinson Posted March 22, 2014 Report Share Posted March 22, 2014 Can anyone tell me when the position of the regulator changed from horizontal to vertical mounting. My car is a 59 model and has the fixing holes positioned horizontally. Bill Piggots book states that later cars had them positioned vertically but I'm not sure when this occurred. I'm fairly certain that my bulkhead has been changed at some point & so I cant trust the location of the holes that are presnt. I'd just like the positioning to be correct for the year of manufacture. Many thanks Graeme Quote Link to post Share on other sites
Lebro Posted March 22, 2014 Report Share Posted March 22, 2014 Hi Graeme. After a trawl throng P.B's "original Triumph TR" book, the only clue I could find is that from TS6001 (Oct 59) new bodyshell tooling was introduced, & also a new loom using spade push-on connectors. Good chance this was the point at which the new spade type regulator was fitted, & at the new angle ? Bob. Quote Link to post Share on other sites

foster461 Posted March 22, 2014 Report Share Posted March 22, 2014 Hi Graeme ~ My 3A is a 1960 post 60,000 model (TS 70470 O) and the regulator is horizontal and the loom is fitted with spade connectors. Tom. I also have a post 60k car built in Jan 1960 and it has a vertically mounted regulator box with spade terminals. Stan Quote Link to post Share on other sites

Graeme Robinson Posted March 22, 2014 Author Report Share Posted March 22, 2014 Mine is TS58872 Aug 59, as mentioned I can't be at all sure that my bulked is original, Graeme Quote Link to post Share on other sites
Lebro Posted March 23, 2014 Report Share Posted March 23, 2014 From all the above I would go for horizontal as being correct, as it is pre 60K, & it would seem that even some post 60k ers are also horizontal. Bob. Quote Link to post Share on other sites
Kiwifrog Posted March 23, 2014 Report Share Posted March 23, 2014 I also have a post 60k car built in Jan 1960 and it has a vertically mounted regulator box with spade terminals. Stan Mine as well built in 1961 Quote Link to post Share on other sites
Don Elliott Posted March 23, 2014 Report Share Posted March 23, 2014 Here is the photo of my control box (regulator) as it cam new on my black 1958 TR3A. TS 27489 LO. The screws for the wires are horizontal. On a late green TR3A I restored (TS 81551 L) the spade fittings on the control box are vertical. It's confusing above what several of you define as horizontal or vertical control box. Don Elliott, Original Owner, 1958 TR3A Quote Link to post Share on other sites
Lebro Posted March 23, 2014 Report Share Posted March 23, 2014 I define horizontal as having the terminals horizontal as in the left hand photo above. This was correct for TR2 / 3, & earlier TR3A's The exact change point is (so far) unknown, but it would seem to be sometime after the 60K changes. Bob. Quote Link to post Share on other sites
Rodbr Posted March 23, 2014 Report Share Posted March 23, 2014 November 1959 Tr3a and TS 615?? Original as far as I can be sure. Quote Link to post Share on other sites
Graeme Robinson Posted March 23, 2014 Author Report Share Posted March 23, 2014 I agree Bob, by horizontal I meant the terminals running horizontally as per Dons L/H photo - Well it's fitted now in this location so thanks for all your comments/ photos, much appreciated.

Ian Vincent Posted March 23, 2014 Report Share Posted March 23, 2014 Here is a photo of my TR3a (TS63xxx L) built on 12th Dec 1959 and taken at the start of its rebuild. I have no reason to suspect that the bulkhead isn't completely original at this point. Rgds Ian Quote Link to post Share on other sites
Lebro Posted March 24, 2014 Report Share Posted March 24, 2014 As a later TR3A TS63xxx that would support all the above ) Quote Link to post Share on other sites
