Hello all,
I am hoping someone can help, I have replaced the fusebox in a 2.5 DHSE P38 and still having the same problem, no power to fuse 26 and relay 19, I believe to be going to the ECM. When I put power to either she will fire up lovely and drives well apart from lots of faults on the dash and restricted to 35 mph. The EAS isn’t doing anything, no fog lights, radio or heaters. I was hoping that the fusebox replacement would have cured this, which is my next avenue to explore?
Thanks
 
Is the fuse box the correct one. There a couple of models to suit the cars specifications. Go back over everything you've done and double check. Was the problem there before you changed the fusé box.

Sounds like your EAS has a hard fault and needs clearing Nanocom or EAS unlock suite is required
 
Fuse 26 is you edc ecu and associated gremlins also connected to fuse 37 (both 20a).
Can’t remember what Relay 19 is. Look it up in searchbar or should be labelled on underside of your fuse box lid.

What Mark actually meant was is the original you took out the correct ANR number for your MY. Most owners are not the original owners and faults occur from previous mistakes
 
I see what you mean, the fusebox that the RR came with part number is YQE, not AMR, the second hand box I bought came out of one of the same year to mine. It is hard to tell whether the lids have been swapped, both fuse boxes have exactly the same problem with the fuse and relay. The scrappers down the road from me are both manual and older, the box’s are slightly different.
 
I have know a chap which is coming to plug it in for me on Monday, does it have to be a nanocoms or EAS suite? I’m not sure if he would have these

From what I see YQE103410 is for a petrol model.
What year and model is your engine??

It is a 51 plate DHSE. The box it came with is YQE000010 and I have replaced with the same number, got a mechanic coming today to try and sort it out, if it’s not a cheap fix then I will be taking the engine out tomorrow as need to get my other P38 on the road, it still has a good MOT, just seems a shame to break this one up if it’s something silly that is wrong, I’m no electrician and a hobby mechanic, used to working on older trucks (fourtraks) with no electrics to contend with. Hopefully it will be good news as I have no hope of sorting it on my own and don’t want to throw much money at it as my other P38 is sound electrically it just needs a new engine. 204,000 miles and I haven’t had any issues with electrics to date.

I hate electrickery myself but if you have Rave work through the circuit diagram and follow the flow of power.I'm guessing that fuse26 supplies power to relay 19 which when energized powers the supply to the ecu.BUT as I have found the fuse box is not a simple bit of kit.I found the pin from the relay that should have sent power to the plug for the o/s heated screen is actually connected through a pcb which is sandwiched between two connection boards,that's the best way I can describe it,hope I got it right in the photos I have put connectors in/on the two pins,looking at the board's they were directly oposie each other and had no continuity, it was explained to me that a pcb was involved. Sorry for the long post but patience and Rave will give you the answer.;)

Thanks for your help, we have been rummaging around for the best part of today wasting time, I can smell trouble with this RR so am going to bite the bullet and pull the engine out tomorrow, will have plenty of DHSE spares for sale apart from the engine and gearbox, the car is burgundy which I haven’t seen too many of, the panels are good and straight if anybody is after bits. Thanks again.
