Xantia Injection Fuse blowing

[soufle]

Hi, I've just taken on a Xantia 97 Turbo CT manual, the previous owner gave up as there is no one to service it around here, and I fear some years of no maintenance have done the old girl little good.

They ditched it because the F7 injection 5A fuse kept blowing. Now I know a bit about old D's but this is all a bit more complicated isn't it?

The injection relay is clicking and the fuse goes every time on start. Whacked a 30A in to nurse it into shed off trailer, I have had advice that there is a short which is most likely due to front end damage but the loom looks pretty good. I've also been advised to get onto it in the dark and have a few bods stare intensely around the bay looking for flashes! So without any diagnostic tools (which Lexia is the correct one to buy and can I scam it onto IOS (I doubt it) and where can I lay my hands on some wiring pdf's for this model, tried opening one members links from a similar thread and server could't locate it.

Where do I start? I am convinced it is something very simple! of course....

Cheers

Steven

ps are RHD front LHM return octopuses available and where to buy one if I decide to go mad enough to try and install one?

Are you sure that F7 is supposed to be 5A? I pretty sure that on a Mk1 V6, F7 is 20A or 25A because it takes all the injector drive current and ignition coil current. I don't have any Xantia documentation here so can't check.

I don't think that Mk1 Xantia wiring PDFs are generally available anywhere, but there maybe someone on here with a printed copy they could scan.

Thanks, Yes I'll check that! The number 7 is going and in the booklet, my only source of info at present labeled as 5A... hmmm

It's a 4 cylinder turbo motor btw.

Just looked up on google, this is what I'm looking at albeit English version.

Steven,

A quick check of the BOL and fuse 7 in engine comp is 5 amp for fuel injection up to 1998 and it is 20 amp thereafter.

I have the wiring diagrams but It will take a bit to search the relevent one out

Steven,

The TCT injection circuits and harness diagrams are in this thread:

I've just repaired the broken links to the diagrams within it..

Hope that helps...

this is good guys! Thankyou. public holiday today= xantia time!

[xantia_v6]

Check the publication date of your handbook. I have a feeling that the fuse layout changed around 1996.

this is good guys! Thankyou. public holiday today= xantia time!

Excellent Success I hope

Could someone with a TCT / Activa check the rating of F7 in the engine box?

[CitroJim]

Yes, later on today.. My Activa is not at my present location. I'll have to travel to it...

20A on my 1996 mk1 Activa.

20A on my mk1 Activa.

That would certainly account for the premature demise of 5A fuses! I hope it solves the problem.

well I'll give a 20 a whirl then! cheers guys. Now I just have to sort the return octopus I upset when I replaced an o ring on the hydraulic pump which caused massive LHM spillage that resulted in me attacking the resevoir filters after I noticed a certain green liquid was BROWN... then onto the rams, boots are completely shagged. This poor car has been owned by academics with little appreciation of what a Xantia needs these days. T.L.C.

And I thought my DSpecial was moody....

[soufle]

just to check as I am completely ignorant, an activa is the same as a turbo CT?

[xantia_v6]

The Activa is a TCT with the extra anti-roll suspension components, the engine and electrics should be identical.

In RHD, all TCT hatchbacks were I think Activas, and all TCT estates were just TCTs.
