Arbcar issue

[RobRainford]

Upon arriving at the girlfriends about half an hour ago, I turned my car off and took the keys out, and the fans and dash lights remained on for a couple of seconds, then it all went off, but the engine management, battery and handbrake light then came back on dimly, can't understand how this has happened, been out in it today a couple of times and nothing was up.

 

Can anybody shed any light on it? It's a Citroen c1. The last bit of work done to it was a catalytic converter in November. Never had this issue before!

 

Cheers

Sounds like a fault with the key switch or ignition relay,leaking voltage through when it shouldnt. Get it to a garage. Disconnect the battery to avoid it going flat,just be careful re-connecting it.

Agree with the above, seems the ignition isnt isolating the supply properly. Cant imagine this is because of the cat change, unless theyve somehow damaged some cables somewhere and theyre shorting which I should imagine is unlikely.

make sure you have the codes written down if you disconnect batery! some of these new cars need a code entered before a re start after power dissconection!

alternator shorting me thinks take the wires off it see if fault goes away etc when field coils breakdown it causes a back feed through earth and lights the dash like a chrimbo tree but might be wrong lol i,am only human but want to help

My google searches had pointed to ignition switch.

 

However, I've been to uni and back today with no issues.

 

I noticed that the rear screen heater was turned on when this happened. And doesn't do it when it's switched off! I'll have a play and see if that's the case.

 

Power disconnection wouldn't be an issue if I took the battery out, I've done it before, the car is way too basic for the fancy stuff!
