FridgeFreezer Posted July 17, 2018 Share Posted July 17, 2018 Is it the factory fusebox or the one added for the ambulance conversion? Defender workshop (RAVE) manuals are in the technical archive and henk's recent thread on manuals, but if it's part of the extra electrics for the conversion you might need the 130 Ambulance Owners yahoo group: https://groups.yahoo.com/neo/groups/127-130-ambulance-owners-enthusiasts/info Quote Link to comment Share on other sites More sharing options...
Mark Farrell Posted July 19, 2018 Author Share Posted July 19, 2018 Factory fitted beside heater matrix , I've fixed the internal light issue so not related. The only info I can find implies its the glow plug fuse but they seen to work and dash light comes on do you have any info on std factory or Ambulance adaption fuse layouts Cheers Mark Quote Link to comment Share on other sites More sharing options...
neil110 Posted July 20, 2018 Share Posted July 20, 2018 (edited) I know it is tedious, but have you tried following the affected cable downstream of the fusebox? To blow a 40 amp fuse as soon as you switch the power on suggests a dead short to earth somewhere rather than a particular component fault unless, of course, the component has a dead short. More likely possibility is a cable has rubbed through somewhere and is touching metalwork Edited July 20, 2018 by neil110 Quote Link to comment Share on other sites More sharing options...
