Member Jonathan Kay Posted July 22, 2014 Member Share Posted July 22, 2014 I think that says "Rover" "54022458". That comes up in several parts suppliers. It looks as if it's also known as "A127", as deduced by Mankee. eg Rimmer Bros. Jonathan Edited by - Jonathan Kay on 22 Jul 2014 09:24:36 Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted July 22, 2014 Member Share Posted July 22, 2014 You're right, sorry. But once you know it's "A127"... A few on eBay UK. Jonathan Edited by - Jonathan Kay on 22 Jul 2014 09:32:10 Link to comment Share on other sites More sharing options...
Big Bad Baz Posted July 22, 2014 Author Share Posted July 22, 2014 Thanks again for the replies chaps. I've gone for the cheaper option and ordered a new regulator. If that doesn't work, at least I know where to go for a new alternator - and even they're not as pricey as I expected! Link to comment Share on other sites More sharing options...
Big Bad Baz Posted August 7, 2014 Author Share Posted August 7, 2014 Right. Finally received and got round to fitting the new regulator. After charging the battery, I fired her up and guess what? The ignition light is still staying on. However, it does noticeably dim when revs are raised to about 3000 - but never actually goes out. The belt is as tight as it should be - should I now be ordering a new alternator? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 7, 2014 Member Share Posted August 7, 2014 Voltage at rest, idle and 3,000 rpm? Jonathan Link to comment Share on other sites More sharing options...
Big Bad Baz Posted August 7, 2014 Author Share Posted August 7, 2014 I don't have any means of testing the voltage Link to comment Share on other sites More sharing options...
Leadership Team Mcalvert Posted August 7, 2014 Leadership Team Share Posted August 7, 2014 Without wanting to state the obvious, buy yourself a multi meter. Easy to use & not expensive and I can pretty much guarantee that this this will not be the only time it will come in useful! Something like this here Also worth looking for alternator reconditioning places (see Yellow Pages) - they will normally test a unit to diagnose the problem for free and repair is cheaper than new....

Big Bad Baz Posted August 7, 2014 Author Share Posted August 7, 2014 The annoying thing is that I did have a really good one that my Dad gave me, but it either got lost in the move here or stolen in a burglary at my old place ☹️ Link to comment Share on other sites More sharing options...
Big Bad Baz Posted August 13, 2014 Author Share Posted August 13, 2014 Right, new alternator received: http://i22.photobucket.com/albums/b337/Sciroccology/Sciroccology008/DSC_0831_12835_zpsd0dab73b.jpg I take it you just undo the pulley thing and replace it with the grooved one from the original?

Tony Whitley Posted August 13, 2014 Share Posted August 13, 2014 Yes and now the fun starts. An air impact wrench is the recommended tool to remove the nut. I don't have one and really struggled. Link to comment Share on other sites More sharing options...
Mankee Posted August 13, 2014 Share Posted August 13, 2014 Echo the impact wrench comment. I have a cordless electric impact gun and it was effortless to swap the pulleys over. You just need to be careful that the belt runs perfectly straight once you've refitted the old pulley, otherwise it will wear out prematurely or get thrown off. I swapped the old shielded fan over as well, as I didn't fancy the risk of debris getting into the alternator. Also marked the nut and thread so that I could see quickly if the nut was beginning to back off. Link to comment Share on other sites More sharing options...
Big Bad Baz Posted August 23, 2014 Author Share Posted August 23, 2014 Right. Pulley replaced (a local garage did it for a fiver!), new alternator fitted (I swear I could remove one blindfolded now) and guess what? My ignition light has gone out and "Napoleon" is back on the road. A good blat to work last night to (literally) blow away the cobwebs. All gauges AOK, no horrible surprises from the enforced time off. As always, thanks for the advice, POB. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 23, 2014 Member Share Posted August 23, 2014 Well done. Please could you tell us what sort of alternator and where you bought it. Thanks Jonathan Edited by - Jonathan Kay on 23 Aug 2014 08:23:55 Link to comment Share on other sites More sharing options...

Mankee Posted August 23, 2014 Share Posted August 23, 2014 Glad you got it sorted. Mine decided to play silly buggers earlier on in the week when I ran the engine up to temperature prior to dumping all fluids and removing the box and engine.
