spiderlane Posted January 3, 2016 Share Posted January 3, 2016 Hi I wonder if anyone can help me identify the fuses on my car? Here is the fuse box :But it doesn't bear any relation to the fuses shown in the wiring diagram or the owners manual (for example I know for a fact that the bottom 10 amp fuse on my car is the windscreen wipers)Anybody ideas? Car is a 2010 R400 with the Superlight dash (Savage Motorsport switches) and Stack.CheersMark Link to comment Share on other sites More sharing options...
SM25T Posted January 3, 2016 Share Posted January 3, 2016 I have a photo of the fuse rail with labels from my 2002 car. No idea if any use ..... can't post here but happy to email by return if you send me your email address. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 3, 2016 Member Share Posted January 3, 2016 I'm not at home and don't have all the diagrams with me... but I haven't found anything that fits that description.Could you pull a few others and tell us what they do?Jonathan Link to comment Share on other sites More sharing options...
spiderlane Posted January 3, 2016 Author Share Posted January 3, 2016 Counting up from the bottom, the 10th one (Red 10 amps) is the 12v accessory/cigarette ligther socket.Will pull a few more and see what they do. Link to comment Share on other sites More sharing options...

spiderlane Posted January 3, 2016 Author Share Posted January 3, 2016 Thanks Ian, much appreciated. I don't think it's a match but are you happy for me to post the image here in case it helps others in the future? CheersMark EDIT : This is Ian's Fusebox Link to comment Share on other sites More sharing options...
SM25T Posted January 3, 2016 Share Posted January 3, 2016 Yes of course. This is a k-series EU3. Link to comment Share on other sites More sharing options...
John Vine Posted January 3, 2016 Share Posted January 3, 2016 A puzzle indeed, Mark. Is your car factory-built? Have you had it from new?I've just checked my fuseboard (2008 R400D, standard dash) and the fuses match exactly your list from the handbook:By the look of it, your fuseboard has a sixth relay, plus associated fuses. Another puzzle. How many of each do you actually have? Also, your relays are fitted the other way round to mine (with tabs at the front).According to the Assembly Guide, both standard and Stack R400s have the same fuseboard. It's almost as though you have a (bastardized?) Sigma fuseboard and relays (21 fuses and 7 relays)! JV Link to comment Share on other sites More sharing options...
aerobod - near CYYC Posted January 4, 2016 Share Posted January 4, 2016 Looks like the layout changed between 2008 and 2010, as my 2012 standard dash R400D also has the 18 fuses and 6 relays that don't match the handbook wiring diagram. Link to comment Share on other sites More sharing options...
Dr Slotter Posted January 4, 2016 Share Posted January 4, 2016 My 2009 Duratec fuse box looks the same as John's. Link to comment Share on other sites More sharing options...
spiderlane Posted January 5, 2016 Author Share Posted January 5, 2016 Interesting stuff. My car was new in February 2010 in kit form and I built it myself. So they must have changed around 2009/2010. I will try to get an answer from Caterham and post back here if I can find anything outCheersMark Link to comment Share on other sites More sharing options...
Dr Slotter Posted January 5, 2016 Share Posted January 5, 2016 Mine was factory built in May 2009. Link to comment Share on other sites More sharing options...

Dr Slotter Posted January 10, 2016 Share Posted January 10, 2016 To close this out, the layout of the current fusebox (relays and fuses), which the OPs looks like it is, can be found in the Owners Manual (cunning!) rather than the assembly guide. You can get it from the CC website if you are logged in. Link to comment Share on other sites More sharing options...
spiderlane Posted January 10, 2016 Author Share Posted January 10, 2016 Thanks, that owners manual is different from the one they gave me with the car (!)However it still doesn't match. The number of fuses is correct (18) but the identifications don't match still. I know for fact that the power socket on my car is at position R (My keyless immobiliser has it's own inline fuse). And the ratings of the others are nothing like mine. The mystery conitnues! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 10, 2016 Member Share Posted January 10, 2016 Can you face pulling them one at a time and seeing what they do?That might help us work out why yours are the way they are, and will certainly help someone else in the future... we just don't know who or when. :-)Jonathan Link to comment Share on other sites More sharing options...
Dr Slotter Posted January 10, 2016 Share Posted January 10, 2016 ============ original post =========Hmm.. my confidence above was based on thinking it was more like this:Edit --- original image removed based on John's suggestion below -----because:- a 'Wehrle 201 101' is the flasher unit- the fuses match on the bottom halfbut...I started comparing at the bottom and didn't compare the top! =========================New image with the top half of fusebox rotated 180 degrees, so the ratings now match.

John Vine Posted January 10, 2016 Share Posted January 10, 2016 In Dr S's diagram, "A" to "I" match ratings-wise, and Mark confirms "I" = wash/wipe. If you reverse the sequence "J" to "R", the ratings match there too (well, all except "R", which is not visible in Mark's photo). Could that be the answer?(Mark, is your topmost fuse 5A?)JV Link to comment Share on other sites More sharing options...
Dr Slotter Posted January 10, 2016 Share Posted January 10, 2016 I think you're right John. Mark said his power socket 10A is the tenth one up from the bottom which matches.I've updated the graphic above. Link to comment Share on other sites More sharing options...
spiderlane Posted January 18, 2016 Author Share Posted January 18, 2016 Great detective work Dr S and JV, you've got it! My top fuse is actually 7.5A but it's definitely the immobiliser, so I'll put that down to an anomaly. So to put this to bed, on my car (a 2010 R400 with push button dash) the fuse identifications are as in Dr Slotter's diagram.I've created an ident sheet and stuck it to the car. If anyone wants a copy of the diagram you can get it here -> https://dl.dropboxusercontent.com/u/13589857/Caterham%20R400%20Fuse%20Layout.graffle.pdfYou want to print it so that the diagram on the first page is 194mm high. Thanks all of you for your help and ideas. Hopefully this will help someone in the future. CheersMark Link to comment Share on other sites More sharing options...

John Vine Posted January 20, 2016 Share Posted January 20, 2016 Brilliant graphic, Mark! I'm going to knock up a modified version for my own set-up, given that the standard label strip is now all but illegible.JV Link to comment Share on other sites More sharing options...
