My cars lights and power pulsing. What can I do?
I've been having this problem for a while but it has recently got worse. I have a 2000 civic lx sedan automatic. When I'm driving my dash lights pulse kinda light they are dimming then getting bright over and over. As I drive the pulses are faster. Recently the power of the motor seems to pulse too. I can feel it in the steering wheel and my feet, but its not too bad. Any ideas on fixing this problem?

Also check the terminals, cause i had the same problem on my 97 coupe and I had a bad terminal wich I changed and problem fixed. Check the alternator first.

All fuses are fine. Battery and alternator passed the autozone test.
If the diodes were bad it wouldnt pass the test, right?
And how would I check the terminals?
Thanks for the help

go to wal mart or autozone and get a terminal cleaner. just clean up your terminals, big 3 never hurt anyone either.. you could possibly get away with using a wire brush too..

Re: My cars lights and power pulsing. What can I do?
An actual Honda dealership tested my alternator once when I went to get a new battery on their warranty. They said it was good. The car wouldn't start a week later so I pushed it off and tested the alt. myself and it was garbage. Then I replaced it. Sometimes "tests" done by other people aren't very good.

Change both terminals, and I bet thats it!!!! cause my car was doing the same exact thing and sometimes It wouldnt even start, I had to move the positive terminal around just to get it to start. ANW they only cost like $3 each...

Re: My cars lights and power pulsing. What can I do?
The belts not like falling off is it. lol sounds like an alt to me.It is similar to have a sub/amp in your car when the bass hits the lights dimm.Same concept really it is drawing power.Thats what a capacitor does it holds a charge to keep from frying your alt.Its gotta be the alt.Althoughhh i remember my buddy having a 6th gen sedan auto with similar problems.His car would pop the fuse for the battery light to come one everythime his key turned ahead.Turned out to be burnt wiring in behind the block below the cooling pipe where there is like 3 unused plug ins.If it pops fuses left and right its worth a shot to check it and not overlook it.
But i have after selling people alternators that i drove in a car and removed.They would bring them to get tested and they come back saying they don't work.It can go both ways.Start your car and get a screw nail wrench anything and see if it sticks onto the back of your alt.That will narrow it down for you

Sounds like the alternator to me. DO you have some gigantic ridiculous stereo system on it thats been beating it to death for a while now? And the testing doesn't always mean anything, especially if its a pimply 16 year old at Auto Zone. Test it yourself a couple times if you can, before and after driving it.

Re: My cars lights and power pulsing. What can I do?
autozone test sucks. all they check for is the alternator is putting out 14 volts or higher. but it doesn't check how many amps it puts out. ie. it should put out between 65-75 amps at 14.4 volts to be good. but you alternator might be putting out 5 amps at 14.4 volts. but would still pass the test due to the voltage matching.

Re: My cars lights and power pulsing. What can I do?
heres a solution.Get your car at operating temp.When it starts to act up removed you battery terminal.If the car shuts off your alt is toast.Do you battery light flick in your dash? Im after been trouble shooting atlernator trouble before by this.If theres a slight hesitation when the terminal is removed its expected but if the car dies you found your problem.

Don't guess, (Don't Blow up your car), troubleshoot
This part is invisible in his sig. You need special glasses to read it. They didn't come with your Civic? You can buy OEM ones at Honda. Cheap too!
...Okay, I'm done ha.
