Its getting a feed from somewhere?

 

The strange thing is while it sat running it was ok. It was even ok when i drove it to the garage, it turned off fine, then a mile or so down the road i pull in and turn it off and all the lights stay on, Yet you start the car they all go off?

 

I wonder if i have have pinched a wire maybe? Also the speedo isnt working, no engine fault codes

I replaced it with a used one

 

The only thing I can think of is a relay that was once there for the fog light mod was powered from dash lighting feed then the spare contacts on the relay have also been connected up to an ignition feed somewhere causing the relay to fail when switched on?

Had another looky today, i cant see anything a miss.

 

Think is going to end with taking it all out again now. I will refit the old loom and see what happens that will rule out the loom being wrong i guess

 

That sucks to hear! Hopefully getting the loom in and out should be an easy job for you now.

Im starting to wonder if there is a relay? or the key itself is at fault.

 

I dont know how they work but i would guess there is a contact inside the barrel that tells the car where the key is? If the lights on where getting a feed all the time they wouldnt go off when the key is turned and the engine is running.

 

However if the car thinks the key is position 1 all the time then that would make the lights stay on?

 

So can someone turn the key one click and tell me what lights up and what works please

Right where is the relay for the dash lighting? I need to pull is and check its not stuck on, that would also explain it.

 

Also would an ECU fault make this happen? Im not sure what i could have done to it but maybe i broke it taking things out?

 

Im starting to think i will rip it all out, buy a new dash loom and ecu and pay someone to put it back in. I really wish i had left it all alone now.
