Loose Cannon 582 Posted May 3, 2012 Report Share Posted May 3, 2012 My alternator gave up the ghost last night, struggling to see the part number without removing it (I need it mobile just to manouvre in/out the garage) Does anyone have the part number to hand for a Valeo 90A? I have read about uprated Bosch units but it looks such a tight squeeze I'm reluctant to experiment with different sized units. ThanksOK scratch that, little camera got it; Ref 2518035 14V 90A A366 Quote In the garage no-one can hear you scream Link to post Share on other sites
Vulcan Grey 251 Posted May 3, 2012 Report Share Posted May 3, 2012 This BOSCH alternator can fit. http://lotusracer.home.mchsi.com/lotustipspage3.htm I had my Valeo rebuilt by a local shop, so it must not be too rare or difficult.

Loose Cannon 582 Posted May 3, 2012 Author Report Share Posted May 3, 2012 Surprisingly difficult to find a parts place or specialist to locate a brand new Valeo unit, however a local outfit has said it can be refurbished for £80 which sounds fair enough.

mr.oogieboogie 121 Posted May 4, 2012 Report Share Posted May 4, 2012 I took my valeo unit to be re-done but it was cheaper to buy a different alternator, think I still have the old vaelo unit though Quote It's Oogies turn to boogie Link to post Share on other sites
GT Andy 0 Posted December 7, 2014 Report Share Posted December 7, 2014 Altenator on my gt3 has failed. I will remove next week, any one purchased a new unit recently or will I need to get the old unit repair. Quote Link to post Share on other sites
Simon350S 192 Posted December 7, 2014 Report Share Posted December 7, 2014 They are cheap to get repaired, have a dig through the yellow pages or Google and see if you've got an old man in a shed near you who fixes them Quote Chunky Lover Link to post Share on other sites
Bibs 11,410 Posted December 7, 2014 Report Share Posted December 7, 2014 They were made bespoke for Lotus by a company in Lewisham whose name I can't remember. I do recall a couple of years back looking through hundreds of pages of alternator brochures and couldn't find a match but as Simon said, they're easy and cheap enough to get them rebuilt.

Loose Cannon 582 Posted December 7, 2014 Author Report Share Posted December 7, 2014 It's also easy for them to uprate the unit at the same time with modern components, think mines pushing out 100+ now Quote In the garage no-one can hear you scream Link to post Share on other sites
GT Andy 0 Posted December 7, 2014 Report Share Posted December 7, 2014 Thanks for confirming, I will get it off and pop around to the local repairer Quote Link to post Share on other sites
GT Andy 0 Posted December 25, 2014 Report Share Posted December 25, 2014 Hi all I have had the alternator repaired and is now refitted, when I start the car the charge light and oil light still light up. When I start the car the alternator does not charge for about 45 seconds when it starts to charge the dash lights go out. I have changed the relay but still the same. Should the alternator charge straight away? any ideas Quote Link to post Share on other sites
Chillidoggy 4,396 Posted December 26, 2014 Report Share Posted December 26, 2014 Yes, the alternator should start to charge straight away, and the charge light should extinguish. Not sure about the oil light staying on, though. Quote Margate Exotics. Link to post Share on other sites
jonwat 435 Posted December 26, 2014 Report Share Posted December 26, 2014 The oil light staying on makes it sound like a poor connection somewhere :-) Quote Cheers, John W http://jonwatkins.co.uk Link to post Share on other sites
GT Andy 0 Posted December 26, 2014 Report Share Posted December 26, 2014 Thanks for the replies, I have been out today. Had a look this morning and found the negative battery connection was loose although the nut and bolt was tight. Will try it from cold in the morning. Quote Link to post Share on other sites
Loose Cannon 582 Posted December 26, 2014 Author Report Share Posted December 26, 2014 Had a longstanding charging problem on stepson's car, many alternators tried without success, as said here loose/corroded connections are often to blame....there are so few in the charging system it's worth testing/cleaning each one. Even if they look and feel "tight" they may just be bound by corrosion - the ring connector at fault in our case had to be tapped apart with a hammer, but it still wasn't making contact when the engine rocked under accelleration Quote In the garage no-one can hear you scream Link to post Share on other sites
GT Andy 0 Posted December 27, 2014 Report Share Posted December 27, 2014 It is working as it should now. 12volt on exciter wire and the charge light and oil light go out as normal. I think I will fit two new more substantial battery lead clamps. Quote Link to post Share on other sites
