The alternator is working fine but when under load the all the warning lights goes on. What could it be?

 

could be you alt still. Did you check for its efficiency? take it to a part source, etc they will test it for you.

 

I even swap alternator with same result.

 

lol all fd's should have warning lights come on when full throttle

 

That is funny ^^ but I need to know what is the problem.

 

Anybody have any idea what could it be?

 

Its your car telling you you shouldn't do that.

 

I have no idea about our cars specifically, but some cars have the CEL come on if the knock sensor goes off.

 

Enough with the joke, this thing is bothering me. Beside the Alternator waht else could cause the warning to come on under full boost?

 

anybody??

 

maybe a bad sensor??? The knock idea sounds possible.

 

are you running a PFC?

 

bad connection somewhere? if it happens under acceleration, maybe something moves around?

you're going to have to open the hood for this, the internet wont fix it

 

I've never heard of this, I know when you get close to the redline the car will sound a buzzer..

 

Your voltage light can come on due to a poor alternator connection, a poor ground, or a loose belt. Check your connections, grounds, and make sure the belt is tensioned properly. I had the same problem on my Silvia and it turned out to be that the belt was coming undone. It was still spinning the alternator but it wasn't up to par...

 

OR it could also be a slipping belt. Check and see how old the belt is or maby if you know when it was last replaced? This was the reason why my check battery light would come on at high RPM, I replaced the serpentine belt for the alternator, problem solved

 

how are you determining that the alt is "fine"
