Door closing.

I've just been mesing around with the wiring on my car again and I think I may have b*ggered something up slightly.

 

When I open either of the doors (not the hatch) the courtesy light comes on, the ignition switch barrel lights up, and the "doors open" telltale on the dash illuminates.

 

When I close the doors, the courtesy light goes out srtaight away but the telltale and the ignition barrel lights stay on for about 5 or 6 seconds, then go out together.

 

I'm sure that pre-messing the telltale used to go out immediately (with the courtesy light) and only the ignition barrel used to stay on, but its one of those things that you don't check out regularly...

 

The annoying thing is that after tonight's exploits I put everything back to how it was at the start of the evening, when I'm sure everything was working OK. Can one of you guys do an idiot check for me please?

Hi Syed.

 

In my car the main light on the ceiling goes out instantly, but the orange symbol on the dashboard to the left of the steering wheel stays on for about 5 seconds.

 

I'm sure they both used to go out instantly.

I've been looking at the wiring diagrams on MKIV.com and I think I know what's wrong.

 

I've been having a look at my alarm wiring and I know the earth wire from the "tailgate open" switch is joined to the earth side of the ignition barrel light by a long length of wire, and in turn to the earth sensing wire from the alarm.

 

The light delay on the ignition barrel works by allowing the earth side of the bulb to stay connected to earth for a while after the door has been closed. Because the earth from the tailgate switch is linked to this wire, it thinks the tailgate is staying open too, and hence the dash light stays on until the delay circuit trips and disconnects everything from earth.

 

Trouble is, i am *sure* it didn't do it before! :eek:

 

Hopefully I've answered my own question. Looks like I'll be trying to sort it out tomorrow.

 

Cheers, Syed & Ian.
