Julian H Posted October 31, 2015 Share Posted October 31, 2015 I would like to change my alternator to a WOSP LMA226, the model specifically for the K series engine. However, it has a different plug to that on my loom. Two problems..1] my loom has two low current cable connections in addtion to the main cable, the WOSP only has one. What wiring do I need to do to make it work?2] where can I get a plug that fits in the WOSPs socket?my Seven's plugthe WOSP's socketThanks Link to comment Share on other sites More sharing options...
Mankee Posted October 31, 2015 Share Posted October 31, 2015 I've just used the pikey method of ramming (insulated) spade connectors on the terminals. Possibly marginally lighter than a plastic plug and you can trim a bit of a wiring down.I have no idea how your BMW alternator wiring works. The WOSP/Denso/Brise wiring has one small cable for the dashboard warning lamp, another small cable for a switched live to "switch on" the field and a fat cable (mine has two) for the positive post that goes to the starter/battery/FIA switch.

Mankee Posted October 31, 2015 Share Posted October 31, 2015 But pennies for a proper plug:http://www.simtekuk.co.uk/product.php/2_way_denso_alternator_connector/?k=:::4464444 Link to comment Share on other sites More sharing options...
revilla Posted November 1, 2015 Share Posted November 1, 2015 That aleternator looks like it might be a direct replacement for the Marelli A115-65 used on the EU2 engines. The plug you have suggests yours is EU3 in which case you will have compatibility problems as the EU3 alternator has a DFM (Digital Field Monitor) connection to the ECU to allow it to compensate idle speed for electrical load. I'm not sure it will be as simple as just changing the connector. Link to comment Share on other sites More sharing options...
revilla Posted November 1, 2015 Share Posted November 1, 2015 Give WOSP a call to check? Link to comment Share on other sites More sharing options...
revilla Posted November 1, 2015 Share Posted November 1, 2015 A quick peep at the WOSP website suggests that if yours is EU3 you will probably need the LMB467 alternator as that is specified for the MG TF '02-'05 and cetainly looks to be the same configuration as the alternator on my EU3 engine.

Julian H Posted November 1, 2015 Author Share Posted November 1, 2015 Hi Mankee, thanks for the info. Andrew, I would phone WOSP but they are quite clear that punters should contact distributors, not themselves. I have had a look at your rather excellent schematics too [thankyou for making them avaiable] but still unsure what to do. I am only changing my alternator to upgrade it [its lighter], not to replace a standard item. Link to comment Share on other sites More sharing options...
Julian H Posted November 20, 2015 Author Share Posted November 20, 2015 All being well, and its not too cold [you should all know by now I am a wuss] I will be fitting my new WOSP alternator. A couple of questions before I start if I may..what torque do I need to tighten the primaries back up to the head on reassembly?anddo i need to put anything on the exhaust gasket [hoping it comes off in one piece!]?Thanks, Julian Link to comment Share on other sites More sharing options...

Mankee Posted November 20, 2015 Share Posted November 20, 2015 I want to say 41-48 nm for the exhaust manifold nuts, but I've never bothered and just hulked them down. Some exhaust systems are easier to get torque wrenches and tools around of course.The exhaust gasket should be a multi-layer steel job. I've reused mine loads of times with no issues, but I await being shot down in flames and will say fit a new one as they are cheap. No goo required, just clean up the head and primaries faces.

Julian H Posted November 20, 2015 Author Share Posted November 20, 2015 It's a K. My initial search bought up nothing, which suprised me!Mankee thankyou. I found this page on the www which is within your number range so will use that. Link to comment Share on other sites More sharing options...

whatsup Posted February 4, 2016 Share Posted February 4, 2016 Julian how did you get on with this problem as my alternator has just expired thanks Link to comment Share on other sites More sharing options...
Julian H Posted February 4, 2016 Author Share Posted February 4, 2016 HiSadly, it had to come off. The Wosp is a fine product and they were very helpful but their l/w alternator does not work with my ECU as it requires signal back from the DFM connection. I will be refitting it when I have an Emerald. Link to comment Share on other sites More sharing options...
Mankee Posted February 4, 2016 Share Posted February 4, 2016 Frank, isn't your Superlight an EU2? If so, fitting a Denso-style alternator is a simple(ish) job. Link to comment Share on other sites More sharing options...
whatsup Posted February 4, 2016 Share Posted February 4, 2016 Julian / Mankee Its a 2002 eu3 but it is running an emerald any info as to this set up would help me greatly Link to comment Share on other sites More sharing options...
Julian H Posted February 4, 2016 Author Share Posted February 4, 2016 Hiya FrankI cant help yet but have an Emerald to install very soonish. Maybe have a look at the software see if there is anything on it about the alternator? It will be a while before I get round to playing with the WOSP again I am afraid.My 2006 EU3 on Rover ECU would not allow charging with the new alternator. I am not sure how it works but I suspect the ECU needs a DFM signal from the alternator to allow it to send a charge out? Grasping at straws here but whatever, correctly wired, I was not getting any output from it whatsoever, and the charge light just stayed on confirming the situation.

Mankee Posted February 4, 2016 Share Posted February 4, 2016 The Emerald isn't fussed about alternator output, save for giving a reading on the live data screen. Mine's an EU3-ish engine with Emerald running an EU2-ish loom and rat's nest wiring. Looks rubbish, works perfectly!What's your current alternator wiring like, Frank? I don't know how the EU3 charging system works, but I can only assume that, for a Denso-style alternator, you do the usual two smaller cables for the warning light and large cable for charging.
