Little Help

[Slammer]

Hi Sorry if I’m in the wrong section but after playing around with a relay in my car today and having no luck I decided to post here.

The problem I’m having is that the lights that I have connected to the relay turn on automatically for no apparent reason (to me anyway ) after an amount of time 30min aprox

Firstly what I’m trying to do is that when I open my doors/turn on roof light, a relay gets tripped and turns on other lights. So I connected a trigger cable to the light on the roof and to the relay. The original lights still works I just made slide connectors

Here is a diagram of how I setup the relay

Real Life

(yes I know that's a 4g cable, dont ask)

All of this works fine the extra lights turn on when the cabin lights turn on and off when the cabin lights turn on. The problem lies as mention before is the just the extra lights turn back on after a period of time thus meaning something is tripping the relay and keeping it on. For the time been I have to unplug the rigger wire.

I’m not very electrically minded, I just know the basics

Any help will be appreciated.

If you leave an interior light on in our cars it will turn off after a while, could have something to do with it...

If I leave the cabin lights and the neon’s on they both do turn off after a period of time. On that note during most of my testing I manually turn of the cabin lights thus turning off the neon’s.

So does the computer/wt ever send a signal after a period of time regardless whether the lights are off to make sure they are turned off? Like reverse flow of current or something?

Also I found that once the neon’s turn on by them self and then I turn the lights on the neon’s they turn off and then back on. hmmmm

If they are not coming on when you have disconnected the trigger wire, that would suggest that the problem lies there. The trigger wire must be suppling voltage because if you had a short in the relay or the wiring it would still happen when the trigger wire was unplugged.

It is strange that your interior lights don't come on though when the trigger is suppling voltage to the relay.

If you have a multi meter, measure the voltage from the trigger wire when you turn the lights on and try to leave the meter connected to the trigger wire and watch what voltage is present when the new lights turn on.

Can you toggle it from the light switch on the ICC? If the new lights come on and you turn the interior lights on and off again do all of the lights go out? Where are you picking up your trigger from, the lights or the door switch, if it is the lights, maybe try the door switch and have a manual overide for when you want them on without the doors open.

my point because if I unplug the trigger wire nothing happens the hole thing is dead.

yep

If I use the lights switch on the ICC the neon’s mimic identically the interior lights thus turning of and on. Also the same thing applies if I open and close the doors the lights and neon’s turn on and off at the same time.

I connected the trigger line to the centre interior light( blue cable I think, it was the only one that worked as desired. The other cable didn’t turn off or of properly.) The lights still works as I just cut the cable and connected the trigger line to the original with slide contacts.

I just tried a different relay and after waiting for an hour the same thing happened.

thanks for the help,

I have fixed the problem

can I ask what it was mate? its got me too.... the positive side should be a green wire with a yellow trace and the negative should be the black and blue? keeping in mind that the system switches the negitive... it should have worked... I would have taken the positive for the relay from the battery saver circuit though, just because it keeps everything on the same circuit...

tell us what you found?

Cheers

Hay sorry for not replaying sooner. I just disconnected the 12v+ Constant opposite the trigger line and connected back to the green with yellow trace. The trigger line is connected to the blue with black trace.

Anyways it makes sense to do it this way originally but so in not sure why I didn’t
