Lights Pulsating.. If anyone can help me out,When ever i start my 2001 Ta the headlights and the gauges pulsate really bad. 
.also while i'm driving and push in my clutch,my volts gauge goes around 10 volts,and goes right back up to normal volts,at the same time my lights go dime,then back normal..I just read on the some page that a coil could be bad??Is this true or could it be the Alt.?Any help??

remove your battery terminals and clean them real good with a wire brush and a can of coke, pepsi no joke. I bet there is allot of corrosion built up on the terminals. It did wonders for my car. dont forget to apply some dielectic grease after your done.
u might also want to check the ponytail wire in the back on the alternator, sometimes if ur power steering pump is leaking a little it will dissolve the rubber piece that seals the water out of the connection to the alternator... so if u get water in there itll stay for a while and mess with ur volts
My lights pulsate too. My battery cables are Super clean and I have NO power steering leaks. Does anyone have a clue what causes this. My volt hands always read good, light just pulsating.

I had this start happening after having to jump start the 7 year old factory battery, which died after being driven all day and shut off for 20 minutes, and driving it home basically running completely on the alternator. I have a feeling the alternator overheats and fries the regulator. I haven't had to replace it yet, but its not going to be a shock like waking up with your head sewn to the carpet when I do have to replace it.
I used to go through an alternator every 10 to 12 months in a turbo 3.1 I had...I know the heat under the hood just cooked it in that amount of time.

I noticed it only after I replaced my dead stock delco battery with an Optima Red top. Only 30k on the clock too. I'm leaning towards the voltage regulator being fried. I too had to jump start my car before the Optima and was probably running on the alternator only.

I had started a thread earlier about this or a similar situation I am having. I notice that when at night when sitting at a light my headlights will go dim then back to normal. My car has always done this. I have changed the battery once so its fairly new.
on my car it did that exact same thing but i was just a lose battery connection i would check all battery cables and test the battery to see if it not staying charged and if not then it is your alenator!
