First radio flickers, and then turns off. lights are dim and rpm starts to drop dramatically. and so the only way i can get my car running is byt keeping rpm above 1 so that i can keep combustion going. I really dont know what the problem is, and I know is not the alternator and is not the ignition. althoguh lately the car has been doing a weird sound, as if the belts were kinda loose. anybody could help me?

btw my car settings, if they are needed to give me any help:

s14
ka24 213100 miles
pretty much stock except for the clutch, and well yeah the parts that i said i've changed.

Check the cables going to your battery posts. Make sure they are not loose & are firmly attached to the posts. Take a voltmeter and measure the amount of current going to the battery as the car idles. You should be averaging a little above 14 volts. Anything higher, (or lower) means your alternator is not working properly. Before you test the alternator, make sure to check the battery cables for any shorts. A short in the wiring can also lead to poor charging of the battery.
Anyhow, hope this helps...
