Member Jonathan Kay Posted May 16, 2023 Member Share Posted May 16, 2023 I have an extensive collection of diagrams! Please send me a Private Message with your email address.And if you can start sketching the ratings of the fuses and what some of them do that will help a lot.Jonathan Link to comment Share on other sites More sharing options...

aerobod - near CYYC Posted May 17, 2023 Share Posted May 17, 2023 One thing I found Jonathan with that fuse listing that is the same for my R400D is that the fuses don't logically go in order from top to bottom, they are sequenced from the centre in this way:Books.pdf Link to comment Share on other sites More sharing options...

BrettJ Posted May 17, 2023 Share Posted May 17, 2023 Image source: https://www.caterham7diaries.com/post/fuse-and-relay-box-layoutOn 420R the diagram by Mark is more accurate than the manual, however the labels are misleading, as having both heated seats on popped the 20A fuse for the "Instruments" Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 17, 2023 Member Share Posted May 17, 2023 That's from a 420, supplied October 2018.Jonathan Link to comment Share on other sites More sharing options...
J888PRB Posted May 17, 2023 Author Share Posted May 17, 2023 Thanks for the help.that coloured diagram is what i found but my fuse board has different Amp fuses in some. all a bit odd. perhaps just had the wrong fuses in.if anyone is willing to add a picture of their fuse board that would be helpful for me to sort thanks again - everyone here always so helpful Link to comment Share on other sites More sharing options...
cobar Posted May 17, 2023 Share Posted May 17, 2023 Looking at the diagrams in #5 and #6, am I correct that is the order when looking at the fuse box from the front? If so, the relays in my 2022 420R are wired in the reverse order. In the picture below, from left to right, #2 is the fuel pump, I'm pretty sure #3 is the starter, and #5 (with the jumper wire) is the flasher. I haven't traced the others. I wonder if the fuse boxes are hand assembled at the factory and some assemblers use the wiring diagram as a suggestion rather than a mandate?

Member Jonathan Kay Posted May 17, 2023 Member Share Posted May 17, 2023 ThanksDo you know why that has the jumper wire rather than a relay or flasher unit?Jonathan Link to comment Share on other sites More sharing options...
cobar Posted May 17, 2023 Share Posted May 17, 2023 Yes, because I put it there :) I am using a Freewheel wireless steering wheel button system that has it's own native flasher relay with user adjustable auto canceling and flasher rate. That jumper gets a redundant relay out of the way and allows things to function correctly. -John Link to comment Share on other sites More sharing options...

MattB Posted May 17, 2023 Share Posted May 17, 2023 The fusebox in #9 doesn't look like any I've seen in a 7 before, and it's very different to the one in my 2021 420.For starters it appears to be in the engine bay?MattB Link to comment Share on other sites More sharing options...
cobar Posted May 17, 2023 Share Posted May 17, 2023 The fuse box is the factory version that normally sits sideways under the scuttle, but is rotated 90 degrees, then inserted into a 3D printed case that protrudes into the engine bay. Here are another couple of photos, but I don't want to derail this thread. Link to comment Share on other sites More sharing options...
