martyn wright Posted July 29, 2023 Report Share Posted July 29, 2023 (edited) Hi! I am now looking to change my Dynamo over to a Alternator! I have looked thro "Rimmers" (Too Expensive) "Canleys and James Paddocks" Is the any other online Stores etc I can look? I was looking at a 65Amp as I want to fit a Cassette/Radio, plus Fog and Reversing Lamps? Would this do the job? or a 18ACR 45Amp?

Paul H Posted July 29, 2023 Report Share Posted July 29, 2023 (edited) I fitted a Denso to my Vitesse and used existing fittings other than smaller fan belt . Working well Paul Edited July 29, 2023 by Paul H Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 29, 2023 Report Share Posted July 29, 2023 well 65 is 3 times more than the dynamo we used the exiting mount with some spacers to align the belts anf fitted an 85 amp unit you dont need anything special but will need to upgrade the charge wire , Link to comment Share on other sites More sharing options...
martyn wright Posted July 29, 2023 Author Report Share Posted July 29, 2023 Hi! So for all that I need 45Amp would do? Paddocks have them for £105.00 with Conversion Kit but doesn't state what the output amp is? Link to comment Share on other sites More sharing options...
Paul H Posted July 29, 2023 Report Share Posted July 29, 2023 I would check if the alternator is branded as there is some rubbish around . Paul Link to comment Share on other sites More sharing options...
johny Posted July 29, 2023 Report Share Posted July 29, 2023 The principal advantage of changing to an alternator isnt really the increase of the maximum output available as its unusual in a classic to install much extra demand (think heated screens and steering wheels, electric mirrors, seats and steering) but the power that can be generated at low revs. Especially if any extra lighting is LED 40amp will be plenty so why carry the unnecessary weight of anything bigger?

martyn wright Posted July 29, 2023 Author Report Share Posted July 29, 2023 Would in that case a Conversion kit fit all Alternators? And if only need say a 45Amp Unit then its not worth forking out extra if Im not going to use it! Link to comment Share on other sites More sharing options...
Paul H Posted July 29, 2023 Report Share Posted July 29, 2023 With a Denso £80 ish you don’t need a fitting kit other than new fan belt Paul Link to comment Share on other sites More sharing options...

Exactly plus the higher the alternator rating the bigger the wiring you have to put in just in case of the maximum current demand (for example supplying a discharged battery). I doubt any conversion kit is going to fit all alternators as they come in a myriad of different shapes however the Denso installation Paul did would be my preferred option....

martyn wright Posted July 29, 2023 Author Report Share Posted July 29, 2023 Hi Paul! there is one on for £81 and the other £91? The first states Not for a 1600/6 Vitesse? Link to comment Share on other sites More sharing options...

The Denso 16404 is designed to fit a Kubuto Digger !!! hence the small size and low output . So long as you get the correct model you will be ok . I have a mark 2 Vitesse so can’t see why it won’t fit a 1600 . The Dynamo I replaced was a C40L Good luck Paul Nb I paid £81 from memory just over a year ago so you are getting a good price Link to comment Share on other sites More sharing options...

Peter Truman Posted July 29, 2023 Report Share Posted July 29, 2023 (edited) I used the original dymno bracket too but lightened it with extra holes? as it was a heavy unit all ok but I fitted a new Lucas 15ACR brought very cheap off local eBay chap brought it for his Lotus but had wrong mounting flange! The daughters Mk2 Spit has a locally made NOS Lucas 15ACR for a Holden it’s a lot smaller sized unit compared to the UK Lucas variant brought very very cheap whilst on holiday in Tassie at a bric n brack shop $15 still going strong after 23 years on that I used the std cast ironTriumph Alt bracket which I had.

68vitesse Posted July 30, 2023 Report Share Posted July 30, 2023 When I converted my Vitesse 2L Mk1 to alternator I used the alternator bracket used on later four cylinder iron engines. As said above needed a different belt and upgraded the wiring. Regards Paul. Link to comment Share on other sites More sharing options...
Paul H Posted July 30, 2023 Report Share Posted July 30, 2023 Assuming you go the Denso route you will be pleasantly surprised how much access room there is Paul Link to comment Share on other sites More sharing options...
rogerguzzi Posted July 30, 2023 Report Share Posted July 30, 2023 Hello All I converted to a Denso Alternator on our Spitfire 1500 and Mk1 Vitesse I went for the 45amp I think they are and you can get at No1 plug now Plus the other reason is we tour in Spain etc and I could get one anywhere if needed!

johny Posted July 30, 2023 Report Share Posted July 30, 2023 Yes I believe apart from being used in diggers and industrial machinery on the continent Denso mini alternators are also used in those micro cars that, as they can be driven without a driving licence, are quite popular there...
