Member Jonathan Kay Posted June 2 Member Share Posted June 2 They're surprisingly repairable. And doing it that way means that it will fit back in and that the electrical connections will connect. Jonathan Link to comment Share on other sites More sharing options...
SM25T Posted June 2 Share Posted June 2 Mine from 2002 k-series was a Skoda Magneton unit. Safest way is to remove it and take it to a local auto electrical service workshop for refurbishment. Then you'll know it fits. Usually a 1 or 2 day turnround 1 Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted June 2 Area Representative Share Posted June 2 Repair should be the preferred option. Supporting local businesses, maintaining skills. Unit Exchange in Borehamwood did a lovely job on one of mine. https://www.unitexchange.com/ Link to comment Share on other sites More sharing options...
Colin_T Posted June 2 Author Share Posted June 2 I was probably going to get a wosp equivalent for it. it packed up in a petrol station, managed to grab a couple blokes for a bump, but by that time it worked again, I presumed maybe it had just got hot and just needed 5 minutes. got to where I was going, and was there a good couple hours but nothing from the starter at all, had to bump it. (starter relay clicks ok) Now I’m back home and it’s cooled down I’ll do some checks and if need be get it unbolted. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted June 2 Member Share Posted June 2 Yes, I'd do some checks before concluding that it's the starter. Check battery fluid levels and top up, as appropriate. Inspect all relevant wires and connections, including earths. Try jump starting from another vehicle or battery. What's the battery voltage at rest, minimum during cranking, and at 3,000 rpm if you can get it running? Do you need a wiring diagram?

Colin_T Posted June 2 Author Share Posted June 2 (edited) Starter relay clicks test light on starter exciter wire confirms voltage present at the starter when start button activated. all power cables and engine earths good. Starter now removed: Bosch 0 986 018 240 Bench tested, given some abuse with screwdriver across the terminals and wired direct to a battery and it burst into life, although got hot VERY quickly. *quickly put back on the car to double check the car side of electrics is 100% working, cranks engine* probably one of them where you could whack the solenoid with a hammer and it would get you going again. but I don’t trust putting it back on the car. Snetterton Thursday so I’ll get one sorted for then 👍 Edited June 2 by Colin_T *retested again* Link to comment Share on other sites More sharing options...
SM25T Posted June 2 Share Posted June 2 Just get it overhauled by experts. Link to comment Share on other sites More sharing options...
Colin_T Posted June 2 Author Share Posted June 2 Probably will do and keep it as a spare, but still going to get a Wosp one. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted June 2 Leadership Team Share Posted June 2 Do you have the additional relay fitted to prevent the “K-Series click”? Even if the car isn’t exhibiting the usual characteristics the relay mod will make the starter work better. The WOSP starter for the K is the LMS430. Stu.

Colin_T Posted June 2 Author Share Posted June 2 This didn’t even click. Relay worked. Power down to starter on exciter wire. Starter didn’t do anything at all. thanks for PN Link to comment Share on other sites More sharing options...
Colin_T Posted June 5 Author Share Posted June 5 Update on this and future info: So my car used a Bosch 0 986 018 240 starter which came up as Ford pinto starter motor and is used with a 26mm adaptor/spacer to use the LMS430 a 22mm adaptor/spacer was required to make the starter engage with the flywheel ring gear.

Leadership Team SLR No.77 Posted June 5 Leadership Team Share Posted June 5 What thickness is the standard Caterham supplied spacer? Edited: I’m sure that’s a stupid question and you’re saying 26mm! I’m using the LMS430 WOSP starter with the standard o/e spacer fitted to my SLR. The WOSP supplied unit has a separate collar, I assume this is sized to work correctly with the standard Caterham spacer. Link to comment Share on other sites More sharing options...
Colin_T Posted June 5 Author Share Posted June 5 (edited) Mine was 26mm (has caterham “7” stamp in it) Edited June 5 by Colin_T Link to comment Share on other sites More sharing options...
