General Electrical gremlins

[waterboy182]

Hi all, just bought a Cinq Sporting and its having a couple of little issues...

If you turn the interior light on the horn goes off, and if you press the horn with the light off it comes on!?!

:bang:​

Any ideas? Also the hazard switch doesn't work, except if you turn it on the indicators wont work, so must be doing something...

​

Help!

I don't know much about this stuff, but looks like a bad earth somewhere. Have you got the haynes manual?

 

[georged30]

it is not a bad earth the previous owner messed the electrical system of the car. if you are not very comfortable with car electrical stuff dont try to fix it by your self.

Are you speaking from experience of this particular car or in general?

i have some experience on this things my opinion is that the previous owner had an allarm system instaled and when he sold the car removed it him self causing all these problems.

OK, so not this actual car.

Its just that I agree with our testicular friend that it could be an earth fault, as both the horn and door switches, switch to earth.

If it had an alarm in it and has had it removed then both circuits with problems(door switches and hazards) are the ones which will have been tampered with. I'd start with a look under the drivers side of the dash for scotchloks or the presence of joined bits of wire/insulating tape/crap wiring. Get rid of anything that looks like it's not supposed to be there then check that the colours match either side of any joins.

personally i think its a bad earth

 

[cojones]

... our testicular friend ...

LOL

 

[waterboy182]

Thanks all, I will update after Sunday :devil:

My initial thought was a bad earth but wasn't sure how this could make the horn and light link...

 

[cojones]

Well, it's not much I know about cars, however I do know a bit about electrics and bad earths can make electric currents go funny.

 

[rallycinq]

LOL

I am correct, aren't I?

Cheers

Waterboy, did you find out what the problem was in the end? I seem to be heading down this route with the horn going off every time turn sharply on the steering wheel or jerk the handbrake.

Also, to anyone who might know... I've replaced the bulbs behind the instrument panel (Rear washer, fog lights etc) with blue LEDs but they are, one by one, turning out and not coming back on again. The clock went aaaages ago and I've kind of got used to it as my radio (now not functioning) had a clock. Anyone got any pointers? I'm looking for physical things I can check on the car. I've heard the phrase 'earthing points' thrown about a bit but where exactly are these (physically) in the car?

Sorry to hijack this thread. I hope someone benefits from it.

 

[rallycinq]

You didn't change the battery warning light to an LED by any chance?

Cheers

[Aliweasel]

Nope, left all those indicator bulbs alone after various warning I've picked from other threads. Only the fog light, rear window heater, rear wiper, healight, hazard light bulb and the bulbs directly behind the speedo have been changed.

PS, Your Throttle body off the Punto turned up over the hols Rallycinq. I haven't fitted it yet as I want to sort out these electical faults first.

 

[rallycinq]

OK, glad the TB turned up.

Electrical problem.

You need a meter, or a test lamp. You need to go round the connections trying to find whether you have power, and if you have power, do you have a return to earth.

I would use a test lamp connected to earth then check for power.

Cheers

I'm heading out to get a multimeter soon as it's about time I invested in one. Where are the earth points (E2 and E6) for the hazards, radio and clock light circuits? Engine bay?
