1998 Hyundai elantra Light problem

Hi again!

I have been having a problem with my headlights. They run normal and then
all of a sudden they get bright(like the brights are turned on)(Also the
inside lights go bright too). I think the engine has a VERY slight jerk to
it like something is pulling from it.
The weird thing is when they are running bright and I turn on the brights,
the lights completely turn off, until I release the bright switch.

It seems to do this randomly but the very slight engine thing is weird.
Anybody have a clue what could cause this? Alternator problem? I checked
for loose connections but could look again? Its just a POS?

Thanks ofr any help.

have u tried replacing your headlamp relay, or worst case senario your alt
could be the culprit.. im hyun tech will have the answer for u...

 

Your alternator voltage is spiking too high. Do not drive your car.
Replace the alternator immediately. These voltage spikes can damage your
car's computers and other expensive electronic components.

 

I just did replace it. It started doing this after I got it. Is it bad?

It sounds like it. Is your battery in good condition? If so, you should
be able to hook a voltmeter to the battery with the engine running. The
voltage should stay steady and it should be between 13.5 and 15.5V.

 

I had the exact same problem in a honda I owned, It was the
alternator. I replaced it, the belt, and the battery (since it had
killed the battery over the weeks it went on)
