Thank you very much guys for all the help!

Sorry for not posting what kind of car I have.
1998 Honda Accord 2.3 automatic EX four doors 118,400 miles.

Sears checked the alternator on the car while it was running.

17 volts is really high and I'm afraid to drive it and make this electrical problem even worst.

Checked the fuses for the left and right headlights and they are not blown.

Should I take a new alternator to my friend since he lives far and don't want to keep driving this car?

Thanks guys.

Ralph
