Yesterday I was playing around in the dash getting ready to wire up a fancy smancy new cigarette lighter that has completely different wiring to what is normally found in a Mitsubishi. It's a "Valeo" normally found in Citroens, Renaults, etc...

Before the new lighter got anywhere near my Magna I managed to short the wires. So this has nothing to do with new lighter.

Result....

Cigarette lighter and lights to ashtray and lighter surround no longer work. :ninja:

I checked the 15a fuse (driver's foot-well), which looked fine (replaced it anyway). Stuck a multimeter into fuse holes an there appears to be no power to that particular fuse.

What else could it be?

Probably unrelated, but my left headlight (low beam only) no longer works. Related?

Did you check the engine bay fuse box for blown fuses?

Did you check the engine bay fuse box for blown fuses?

No. Do you know of any fuses that may be related in that box?

I will check them tomorrow morning thanks.

There's a 30A fusible link in the circuit but if that's blown a whole bunch of stuff will be inoperative, such as hazards, audio, cruise, washer, wiper, and starting the car. Basically it protects the ignition and accessories circuit. The lighting for the socket is via a 10A fuse in the engine bay box associated with the tail lights but the socket should still have power if this is blown, it just won't be lit up.

Just checking, when you checked for power at the 15A fuse, did you run from either side to an earth? Measuring across the fuse won't read anything unless there's something using power in that circuit.

No, I didn't check the fuse using a link to earth. So it may have power after-all

I will check that 30A fuse in the engine bay in the morning, even though those things you mentioned are still working.

I'm hopeless when it comes to electrical issues.

I really appreciate your help, thank you :D

And make sure your key is at least on Accessories

And make sure your key is at least on Accessories

Will do, thanks. :)

Not trying to hijack the thread, but thought it an appropriate place to ask a couple of elec questions also...
TJ...with car on Acc...
I Can operate everything electrical...wipers, cig lighter, radio, trip, even dash fan.

When I go back to OFF, Trip computer still illuminated, radio still works, rest is off. (trip illuminated and stays on set speed regardless of previous display mode)

Then go to key out...radio still works..(have to push radio power button again)...stock mitsi cd player

Is this normal??

Thanks

I don't know much about vehicle electrics, but it sounds like a relay issue. I'm sure someone more knowledgeable will be able to shed some light on the issue.

Check the fuse in the yellow box located in the engine bay

Ensoniq5 you were correct. When I checked the fuse using ground (and the key turned to accessories like shezza said) there was a healthy 12 volts. :dancin:

Although now there are new weird issues...

I now have the cigarette lighter working, but... when it is pressed in my left head light works and my stereo back lights work, but not otherwise. My climate control button lights don't work at all, although the screen displays normally.

Short of seeing an auto-electrician I think I'll swap out the relays, etc in the engine bay. Obviously something isn't working properly. :ninja:

Is there any chance you've mixed up the socket power wire and the socket illumination wire? If I'm reading the diagram correctly the power wire is blue with white stripe, earthing via the black wire. The green/white wire powers the lamp, earthing though the dimmer via the black/yellow wire. Importantly, the two circuits should be treated entirely separately with no shared power or shared earth, if the socket you're using doesn't work this way you might need to leave the illumination wires disconnected and put up with a dark socket.

I think you may be right again. I found that a couple of the wires did not have power no matter what I did with the multimeter, so I hooked up the lighter using the one wire that did have power and earthed it using the other wires earth. Mixed up like you said.

When I get a moment I'll go un-mix it and see what happens.
