Scooby Jim Posted October 20, 2012 Share Posted October 20, 2012 Hi I currently have a Lucas 18ACR alternator on my Series V8, and I'm after something that can do a bit more than 45amps. As I want to eventually fit a winch and spot lamps / flood lamps. What can I directly fit in the place of the 18ACR, obviously not concerned with upgrading the cabling, as I'm going to do that anyway. Just surprised its such a large alternator and produces only 45amps, I have had one 1/3 the size that produced more. Quote Link to comment Share on other sites More sharing options...
Scooby Jim Posted October 21, 2012 Author Share Posted October 21, 2012 Failing an upgrade, can anyone confirm what these connectors do? Obviously the larger is the main charge, but what are the other two?? The only replacement connector I can seem to find are two large connectors, one small.

western Posted October 21, 2012 Share Posted October 21, 2012 the diagram in http://forums.lr4x4....showtopic=44909 should explain a Lucas 17ACR 65amp unit might fit, but you'll have to upgrade the main battery feed & starter cables.

I'll have a look for that alternator. Only thing that bothers me about the diagram is that it shows two large connections, marked as +ve and one small. Mine has One large and two small, which may sound like splitting hairs, but I just want to make sure its right. I've a Bosch 120amp alternator from a Vauxhall in my garage and was going to see if that would fit as its only a main thick cable and a battery warning light, and I've the Vauxhall cabling here, but it won't fit the bracket.

dave88sw Posted October 21, 2012 Share Posted October 21, 2012 I can't see it very well but i think that mount would accept any lucas a127 alternator, of which many amp ratings are available, i had an 85 amp one from a classic rangie on mine Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted October 21, 2012 Share Posted October 21, 2012 I would go with the A127 flavour. Quote Link to comment Share on other sites More sharing options...
western Posted October 21, 2012 Share Posted October 21, 2012 http://www.mgb-stuff....uk/altplug.htm the 7th & 8th photo's might help, one will be the charge waning light & other will be the feed to battery/starter. Quote Link to comment Share on other sites More sharing options...

Interesting if you look further down you can see the same alternator as mine and its correct plug. Looks like its a "battery sensing" model???

dave88sw Posted October 22, 2012 Share Posted October 22, 2012 that bracket will definitely take an a127, it was used on a large range of vehicles, tdi's, v8, 2.5 petrol etc. occassionally the mounting lugs are opposite but this can be changed, you simply take the through bolts out and rotate the front housing without pulling it apart then replace the through bolts.

Cool will have a look. Where can I get hold of the correct terminal for the alternator?? Quote Link to comment Share on other sites More sharing options...
western Posted October 22, 2012 Share Posted October 22, 2012 any auto electrical suplier should be able to get you a new plug kit, Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted October 22, 2012 Share Posted October 22, 2012 If you go above 55amps on A127 models they would normally be bolted connections for the wires. Quote Link to comment Share on other sites More sharing options...

Scooby Jim Posted December 2, 2012 Author Share Posted December 2, 2012 May have tracked down a LRA604 which should do the job. Can anyone say if there is any reason this would not fit?? Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted December 2, 2012 Share Posted December 2, 2012 Whats an LRA604? Quote Link to comment Share on other sites More sharing options...
Scooby Jim Posted December 2, 2012 Author Share Posted December 2, 2012 Its a 70amp Lucas alternator, supposed to be fitted to a Ford but has been on other things. Looks like this. Quote Link to comment Share on other sites More sharing options...
