So I deleted my original thread because I thought I would have to take it to the dealer for warranty and didn't want anything floating around on the internet. Long story short, I tried to install LED blinkers with resistors and my whole car's electrical system went crazy on me. Could not start it or roll up the windows or turn on the lights or anything and eventually the battery completly drained.

So I took everything off and unplugged all I could then put the battery on a charger for a while then jump started it. It started up ok and everything seemed to be working fine, except for a CEL light. I cleared it, but will watch for it to come back.

Lets just say I am NEVER messing with anything electrical related again! That scared the living **** out of me.

Thanks to ModMe and others for the help and advice they gave me yesterday.

 

Good news wake, thought you were gonna be SOL man.

 

Good to hear.

Yeah, unlike cars from just a few years ago, these things have way too much going on and it's all very integrated. I'm staying away from fussing with that stuff.

 

Yeah I am done with that. I was about to start freaking out this morning.

 

It's perfectly fine to work on electrical things in your car. If you know 100% what you are doing. If not, leave it the hell alone or it can get really expensive really fast.

BTW, the smart thing to do was to see what the CEL code was before just clearing it. Especially after your electrical debacle - I can't imagine why you'd just ignore it like that. It's never a good idea to just clear it without knowing what it is, I hope that doesn't come back to bite you in the butt.

 

Haha. You erased the thread right when I replied.

When you said your lights started flickering and make buzz noise I already knew your battery was low.

 

Back in the day.... (not sure which, as I only learned this about 15 years ago), there's an acronym.. KISS. It's not meant to be offensive in any way, but it's really applicable in many situations.

KISS acronym

Always a good idea to revert back to basics to figure something out. A battery guage might of been useful in this case, or a multimeter. I suspect if you reinstall your lights, you'll be ok.

The bigger question however, why was your battery run down. Having marker/turn lights on, or door open for an hr shouldn't kill your battery unless it's in a low state to begin with. Is it in a low state because it's just old and worn, or is there some underlying electrical issue keeping your battery from getting fully charged......{hmmm}

 

I wrote it down and looked it up before I did. P0603 was the code. This explains it in more detail http://engine-codes.com/p0603_nissan.html

It says to first try charging the battery and clearing the code. Then if it comes back look into it more.

Don't worry, I'm not that stupid to just blindly clear it without looking. lol

 

Haha nice. I'm not offended. The way things were acting so strangly I thought it had to be something more serious. I've never heard of anything acting this strange with just a low battery. It wasnt just the lights. The entire car was acting crazy, even my radar detector started freaking out on me and the locks on my door were clicking on and off at times.

Yeah I think the battery might be going bad, even though this is my 3rd one from infiniti. I'll get it tested at autozone today.

 

With the car idling, what is the voltage across the battery terminals? What about say 2K rpm?

 

I have had batteries that when going out would make the car do some pretty strange stuff. Hopefully that is all it was.
