Colin Grundy Posted August 20, 2002 Share Posted August 20, 2002 In amongst my various boxes of bits I have found a black MG Rover box in which is a square relay sort of thing. The part number is YWB 10022-F. I cant find any reference to it in the assembly guide. The aforementioned object is approx 3" sqauare with (Ithink) 4 or 5 pins which something obviously plugs into. Could it be the immobiliser? All suggestions welcome! Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted August 20, 2002 Share Posted August 20, 2002 Does it have a round button on it? If so - Inertia switch? just guessing. No Parts labled Rover on my car! Link to comment Share on other sites More sharing options...
Colin Grundy Posted August 20, 2002 Author Share Posted August 20, 2002 No round button Alex, but thanks. I suppose the obvious answer would be to ring tech. support, but its probably quicker on here. Link to comment Share on other sites More sharing options...
Miff Posted August 20, 2002 Share Posted August 20, 2002 i got a spare relay with mine. It was located in the lower part of the fuse wiring and since not actually located it dropped out on the first road-test. After an hour of trying to work out what electrical bits weren't working i rang caterham who said it was 'spare'. There should be three relays, one big and two small (i think) plugged in and a spare slot at the very bottom. oops, re-reading your post i think your part is considerably larger than the spare relay i had, sorry for the misinformation.

Mole Posted August 20, 2002 Share Posted August 20, 2002 Could it be the Multi-Function Unit (MFU) that fits above the ECU. I think that it's a bit bigger than 3" square but it certainly comes in a black box and has a multipin connector (a bit like the connectors to the ECU but not so many pins). The ECU was pre-fitted to my car but the MFU wasn't and was supplied separately. Can't remember the part number but I could always send a picture of it if it would help identification. Miff - maybe your "spare" was the one that was missing from my car? JFI (just for information) there should be four relays - three identical ones in the the top three slots (horn, lights and something else), and a fourth larger one (flasher unit) below with the last slot unused. Keep flying low Mole @ the animal with attitude (well almost!) Edited by - mole on 20 Aug 2002 12:24:45 Link to comment Share on other sites More sharing options...
Fred Posted August 20, 2002 Share Posted August 20, 2002 Hello colin the part you have is a engine managment relay from a mini or a metro 95-96 it may be spare best to ask caterham if not you will have a non starting caterham I HAVE A DIRECT LINK WITH THE ROVER PART COMPUTER fred Edited by - fred on 20 Aug 2002 13:57:14 Link to comment Share on other sites More sharing options...
Colin Grundy Posted August 20, 2002 Author Share Posted August 20, 2002 Thanks for your reply guys. The MFU is a very likely possibility, but as I ordered mine as a kit and I havent speced the engine yet I thought the type of MFU would depend on the type of unit you finally chose. All I told Caterham when I ordered it was that it would have a 1.8K series fitted, but I haven't decided on SS or V VC yet, but thats another story!

Colin Grundy Posted August 20, 2002 Author Share Posted August 20, 2002 Relay box it is! Thanks guys for all your help Link to comment Share on other sites More sharing options...
Miff Posted August 20, 2002 Share Posted August 20, 2002 Mole, I still only have three relays fitted and everything works fine! The fourth was rattling around my passenger footwell until last week but seems to be doing it's job fine from that position. Link to comment Share on other sites More sharing options...
Colin Grundy Posted August 20, 2002 Author Share Posted August 20, 2002 Thanks to Darren Phillips who's kindly responded. The part is in fact an MFU for an EU2 spec engine. When I come to spec and purchase the engine they will swop the unit for the correct one. Link to comment Share on other sites More sharing options...
