SERIOUSLY! I'm sure someone here can help. half of you seem to be extremely knowledgable. PLEASE HELP!

The symptoms you describe indicate that the bulb-check-relay is energising, this only happens when the alternator isn't charging (or isn't appearing to be charging).

Now there could be several things causing this fault, the alternator, the wiring or the relay itself.

Realistally te alternator needs to be tested for correct voltage output when on the car & possibly also bench-tested by your local sparky.

The bulb-check circuit has the benefit of being a really big, confusing voltage warning system, so if you miss the little picture of the battery glowing, the rest of the dash lights are still staring you in the face!

All is sorted!

Ok I got another alternator to put in and I installed it. Started the vehicle and the lights were still on...

So I went back and looked at the wiring and I saw that the wire going from the alternator to the starter motor was half melted and had soldered itself together to the crimps and the wire was corroded green. So I replaced that and everything is fine now.

So maybe all along the problem was just that wire...

good to hear you found the problem. I did mention to check the charge wire on the back of the alt. Its not uncommon for them to come loose, alot less common for them to burn out!

yep sounds like a charging problem. could be as simple as the fan belt loose/slipping, or wire fallen off the back of the alternator. Or it could be the alternator itself, but it pays to chack the basics first...

      Thanks for your insight, it being basically useless will impact my decision for sure. I thought it may help the engine breath better I guess. But then again, I have also been told that tuning an RB20DE is also not worth it. Exactly, we follow EU Regulations. There is a bit more leeway on older vehicles. My Porsche 924 came without a cat from factory and managed to pass, they still mentioned that I have quite high emissions on it though.

      My apologies, I stand corrected. Thanks for registering to mention this! And thank you for actually reaching out to the council to clarify. This is the sensible thing to do and the opposite of what I was alluding you were doing. I may have seen too much outrage and hate being fueled on the internet and it has made me a somewhat cynical old man. Sometimes it is easy to forget that there are real people behind websites and accounts. In my defence, CarExpert and CarExplore do read quite similarly at a glance. I shall try and do better in the future. (Please stick around to get the latest scoops on dealing with old Nissan shitboxes )

      Don't bother. The poor little RB20 doesn't make enough gas flow to challenge the flow capabilities of even the littlest cat, and you won't make any extra power, and all you'll do it soot up your rear bumper. Plus....is Malta not runing under Euro regs?

      Hey Daniel, sorry to hear that and thanks for posting up for us at a really hard time I only knew SmoothLine through the forums, we never met as we are based in different states, but when he was most active on here he was quite a while back so not many of the current crowd might remember him. I am pretty sure he was active in the Queensland SQU club but that is defunct now too (times are changing and we are all getting older). Farewell SmoothLine!

      Turns out depending on whether the car was equipped with TCS or not there are different signals coming to the dash, meaning there are different speedo clusters.  Wired in a speedo calibrator box from aliexpress and now works fine.
