Headlight, dashboard and defroster fan problem!

Hello!
I own a 1990 Honda Civic, 4-door/4 cylinder car. When driving, I
noticed that my headlights and dash board lights get very bright, then
dims back to normal. At the same time this happens, my defroster fan
motor, speeds up and then slows down to normal in conjuction with the
headlight and dashboard lights.

I also notice that my battery light on my dash board flickers on and
off occasionally apart form the dash board lights.


Oh by the way,

My alternator was replaced March of 2003. Prior to changing my
alternator, my battery light constantly stayed on.

My mechanic recently checked my fan belt and told me that it was o.k.

Does anyone have a solution to what this problem might be?

Sounds very much like a faulty voltage regulator. Also check the fat
battery / alternator / starter wiring and ground straps for loose /
corroded connections.
