In Need if Help with Signal lights: Constant on

Hello,

Has anyone experienced their signal light being constantly on when parking or headlights are on?

 

I'm putting my car back together after painting. I didn't pull out the hole chassis harness.

I hooked up the chassis harness in the bay along with semi-installing a new ecu harness.

 

I put power to the car today to play some musicand check on thing while I worked.

I noticed when I put on the parking lights that the left rear signal was constantly on. I thought for whatever reason. All the signal light needed to be install. The rear left signal did turn off after all the other signal bulbs where installed, but now the other 4 are lit. The left 2 are brighter than the right. I noticed that if u pull out the front left bulb them the left rear turns back on.

Strange.

Hazards work fine. Activating the signal from the stalk works. I unplugged the signal stalk power to see if that may have been the issue. Removed the fuse for the signals and they stay on constant but not blink.

 

I have LED 194/T10 bulbs. They're not switchback.

Things worked as normal before I took thing apart and painted. The only new things I wired were two removed leads to my fuel pump relays.

 

Could it be the stalks? I bumped them plenty while working. Just from today I assessed them good and no flickering from contact on so it's hard to say it's the stalks.

 

The issue somewhere in the chassis harness?

Did some more messing around with this issue.

I think the stalk is the problem. i wiggled it around a bit. When i went to put the signal up for a left turn, all the signals blinked lol.

I'm gonna try and clean the tarnish off the copper and see if that works.

this still doesnt explain why the left side/fronts are constant on ACC/On after i pulled the stalk. may be a ground from the stalk thats causing it.

IDKkKkKk. I'll report back

Are you sure you can use LEDs in the indicator lamps? On a car that old? It doesn't work on many old cars because the indicator relay can't cope with the wrong impedance out at the lamp positions and the LEDs will happily light up even with minimal current flowing through the indicator relay.

And when I say "indicator relay" I mean the flasher, not a relay relay.

Beyond that, I would say that you have caused yourself a wiring fault and that you would be well advised to work through the wiring diagram and the actual loom with a multimeter.

I've had these LEDs and a LED EP34 flasher relay in the car since 2020.

No fuses were popped either.

I'll multimeter and clean off the tarnish tomorrow. From how the lights were acting after I diddle the stick make me lean towards a stalk problem.

That would be a rarity.

You can emulate the function of the stalk just by bridging the appropriate pins in the connector. If you can make it function correctly by doing so, then the wiring etc is OK and it is the stalk.

SOLVED

 

simple solution.

After wrecking by brain, i ended up jist giggling everything i could.

At one point last week I noticed that the left side signals shut off for a split second. I wasn't sure what triggered it.

I spent time cleaning up wiring, re-wrapping and adding DT connectors to my IC7 stuff.

I bought a new hazard and stalk hoping that would work. The stalk did fix some function issue but not the steady on. Hazard didn't fix it.

I started just tracing everything. Once I got to the engine bay I notice my engine harness was droopy. I started moving it and the signals flickered. Come to find out that the starter + turned off sigmals when it grounded out on a bolt

I have a Wiring Specialties pro harness so I'm not sure if this is specific to it.

So it should work proper once I hook everything up

That is a dead f**king short of B+ to ground. Scary.

Yeah I'm terrible with understanding wiring. Outside of being given install instructions, I have a hard time deciphering diagrams and terminology.

I have the wiring manual and its all hieroglyphs lol

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
