Xantia Dash Lights not showing when ignition turned on - car won't start

Post by Gordon »

Happy Christmas wherever you are, and apologies that this is a question about a Xantia but I'm in Oz on holiday and our son has the Xantia back in NZ that won't start. On turning ignition key the only dash lights that come up are the battery and the handbrake. On turning further to start the starter motor operates but engine doesn't fire. When all dash lights came on the engine did start without trouble but it is now back to its former self with the main warning and ignition lights out and the car unable to start. Being in Oz I'm not able to provide any more description, and my son doesn't have mechanical or normal testing equipment - fuses were checked and are ok, ignition barrel was removed but contacts can't be easily accessed. I'm assuming it is something electrical, but my question is what turns on these main ignition lights. In the first two positions of the ignition key these should light up, so do I suspect something wrong in the ignition switch, or is there something else that I'm not aware of. Again apologies for limited information but I'm trying to help my son remotely. Cheers,
Gordon

Sounds like faulty ignition switch. You can try rattling or pushing the key to different directions while turning the ignition on and see if it makes any difference. If the starter didn't turn, my suspect would be the battery terminals; remove, clean (both battery poles and the clamps) with sandpaper if a battery pole brush is not available.

If you can tell me the trim level and engine type, I should be able to find the correct wiring diagrams for your Xantia. [edit] I see it is in your sig, I will see what I can find.

There is a fairly common failure in the Xantia, especially in hot weather, due to metal fatigue in some of the soldered connections in the dashboard fuse box. The exact symptoms vary according to changes in wiring for each production year. The fuse box is a bit awkward to remove, and a bit of skill is needed to re-solder the PCB connections, but it is fixable.

The other common electrical failure with similar (but random) symptoms is a break in the wiring in the big harness that runs under the radiator on RHD cars.

I do have the correct wiring diagrams (does your car have a catalytic converter?), but as there are quite a few pages and the files need to be re-formatted, I won't start until you confirm that you want them.

Thanks very much for your advice. We've had to admit defeat mainly because the car is in Wellington, and having returned to NZ I'm resident up in Whangarei a distance of 805km. We'll get the AA to transport the car in Feb, and then I'll try and determine the cause. It is a 94 Xantia SX 2.0, petrol without cat converter. Certainly the wiring diagrams will help and will be much appreciated if there is someway of posting them for me to access. Thanks very much. Gordon

When this happened on my Xantia, I checked for 12V at each fuse that should have been live with the ignition on, and found that some of them had power but others didn't, and managed to fit a shunt wire to the dead fuse holder (from the fuse side) to get the car home. Here is the story: https://www.frenchcarforum.co.uk/forum/ ... 83#p377280


It looks like I may not need to redo the diagrams as a similar set is available on FCF: https://frenchcarforum.co.uk/forum/view ... hp?t=26492 and the fault described there is the other common one.

Thanks very much for your advice. When the Xantia finally gets trucked up from Wgtn I'll have a go to fix and let you know. cheers Gordon.
