My battery light on my integra is turning on at idle and in low at low rpm's like about 2k rpm
And its makin a humming noise kind of, the only way I can explain the noise is it sounds like my intake but deeper and more noticably loud...
and i can just tap the gas and the light goes away instantly and it seems to be running fine
But there is a wierd smell, sorda like a burnt clutch smell..
Can someone please help me! It is my 1990 integra rs hatchback, daily driver.
Battery replaced less than 4months ago
Clutch is fine, just smells like the clutch

 

It's your charging system. Check your alternator, it might be going bad. I don't know what's up with the sound but the smell is probably coming from the alternator. I had a funny smell coming from the engine bay, it smelt like burnt electronics but it was the alternator.

 

how do I check the alternator, if it is going bad..?

 

Oh and i just took it for a ride around the block a few times, runs fine, same idle as before a little low... and the battery light now wont turn off at all.. I bet it is the alternator because I idle pretty low, my lights dim down at low rpm's and my stereo flashes n stuff, and I just put a 300watt amp and a big sub in the car, that might have just finished off the alternator
How do I check if its bad, or dieing lol?

 

Alternator is most likely the problem. You can take it off and up to autozone and they will check it for you (tell you its bad and sell you a new one for about $250).
