Driving a 2000 Honda Accord EX w/ about 90,000 miles.

I started having trouble a few months ago with my SRS light coming on
and staying on. My mechanic re-set it once, but after a week or so it
came back on. We then had to replaced the SRS unit.

Ever since he replaced the SRS unit, the red SRS idiot light comes on
for a few seconds to a few minutes every so often and then goes out. He
checked everything and said it was nothing to worry about.

Then, about 2 weeks ago my background lights started flickering, along
with my headlights. We immediately thought alternator, so we took it to
the Honda dealer.

They did the 90,000 mile check and found nothing wrong with any of my
systems. But they agreed the flickering background lights sounded like
an alternator problem and for another $400 they'd be glad to replace
it.

We took the back to our regular mechanic, who replaced the alternator
(under a warrantee from the replacement of the alternator 2 years ago)
for$70 (labor). This did not fix the flickering light problem??? We're
scheduled to go back to our mechanic on 9/18 to have him check the
electrical system.

Today, the red battery light kept coming on and going off (along with
the red brake light, and all the door and trunk idiot lights). They
finally stayed on. It seemed they would go off at stop lights and then
come back on after the car started gaining speed. The fan was also
blowing in time to the rhythm of the flicker (very strange)!

Book says it the alternator??

Anyone got ideas.
