Davemate Posted March 6, 2016 Share Posted March 6, 2016 What alternator do I ask for at my local car spares, looking at pictures it looks like an ACR but which one 15-16-17 or 18 Quote Link to comment Share on other sites More sharing options...
Dogsbody47uk Posted March 6, 2016 Share Posted March 6, 2016 As far as I know the only difference is the amps output. How many do you need? Mine gives 36 amps. I think it's a 17 Acr, but I'm not sure. Cheers, Dave. Quote Link to comment Share on other sites More sharing options...
Davemate Posted March 6, 2016 Author Share Posted March 6, 2016 Will it fit a 2.5 with HS6 carbs, not sure if I'd read that a "A" type won't fit, quite happy to be wrong Quote Link to comment Share on other sites More sharing options...
Matt George Posted March 7, 2016 Share Posted March 7, 2016 I've got an 'A' type fitted to my 2500 on HS6s. From memory the clearance is tight between the battery and alternator, but it does clear. May be due to the fact that the battery is quite a big one.My unit is an uprated 65amp one for a Stag. Something like this…http://www.ebay.co.uk/itm/NEW-.....MH5l-1Fv09Qb-eG0jQKgCheers,Matt Quote Link to comment Share on other sites More sharing options...
piman Posted March 7, 2016 Share Posted March 7, 2016 Hello Dave, The 17ACr is known as an LRA100 in the market place I believe?Alec Quote Link to comment Share on other sites More sharing options...
RobPearce Posted March 7, 2016 Share Posted March 7, 2016 Quoted from piman The 17ACr is known as an LRA100 in the market place I believe? Almost. The 17ACR is an original fitment / brand new Lucas part, where the LRA100 is (or certainly used to be) a reconditioned one. It's meant to be compatible but may not match identically.

Davemate Posted March 7, 2016 Author Share Posted March 7, 2016 Thanks chaps,my local car spares gaff is quite large and they normally go by your reg but I don't want a dynamo Quote Link to comment Share on other sites More sharing options...
piman Posted March 7, 2016 Share Posted March 7, 2016 Hello Rob, whenever I wanted an alternator and asked for an ACR17, the LRA100 is what I was given, it looked brand new and I didn't put my old unit in?Alec Quote Link to comment Share on other sites More sharing options...
RobPearce Posted March 8, 2016 Share Posted March 8, 2016 Quite likely, Alec. I suspect the distinction faded out rather as the ACR17 became obsolete - some time in the 1980s. Quote Link to comment Share on other sites More sharing options...
piman Posted March 8, 2016 Share Posted March 8, 2016 Hello Rob, " some time in the 1980s"That's fine, my cars a 1968 and so is my mentality.Alec Quote Link to comment Share on other sites More sharing options...
Davemate Posted March 12, 2016 Author Share Posted March 12, 2016 New alternator fitted so now on idle no more red light coming on 🙂 Quote Link to comment Share on other sites More sharing options...
TedTaylor Posted March 14, 2016 Share Posted March 14, 2016 From the early 1990s when Steph and I used to Autojumble as sellers and buyers I acquired a couple of genuine Lucas alternator conversion kits. Filled the May 1965 kit into the July 1964 Mk1, quite a faff to fit but kept things in period.MUT Quote Link to comment Share on other sites More sharing options...
Davemate Posted March 15, 2016 Author Share Posted March 15, 2016 Quoted from Spitfire6 Hi Davemate,Nice one.What alternator did you end up buying to fix the problem? What do you think was the problem on the old one?Cheers,Iain. I'll have a look at the box tomorrow to see what I bought !Anything under about 900 revs and the ignition light came on.Now the alternator is fitted I've noticed a few things Indicators flash quicker even on tickover and the indicator lights on the dash seem brighter Headlights seem a touch better Quote Link to comment Share on other sites More sharing options...
