well i noticed this last night when i was drving home that all my lights in my car and my headlights were pulsing?!?!?

does anyone no what this could be from??

only thing i did was install a ex cluster


help please

 

mine lights are pulsing too, i'm thinking it's a bad ground....

someday, i will try to replace some grounds with 4ga or 8ga audio wire

LMK if you get the problem fixed

 

i just really have no idea of what it could be.....

it really bugs me

 

it bugs the **** out of me too. I'm not sure which civic you have but I've been checking the wiring diagram and it might be either ground located behind the driver and passenger side kick panel...

*shrugs*

 

it seems to be a common problem. i think its due to small weak alternators

 

so the alternator needs to be replaced? I checked mine and it is getting 16-17 volts like it should be

 

That's exactly the same thing I've noticed on mine. It's been happening for a year or so, intermittently. I've also had the SRS (airbag) light come on during driving during extreme pulsing periods.

Is this a cut and dried problem with a bad ground? Anybody know exactly where the ground is that might be causing this?

 

it will charge the right amount of volts, it just dosent put out many amps. i think its somewhere in the 60 to 80 range.

 

well today it quit for a min and when i hit the brakes it came back on, then back off again...

also my speedometer has quit working when it pulses also

lol alternator should do 14 volts, and you need to test the amps not just volts.
if it does 14 volts at 4 amps it will take days to charge the alternator.

WOAH!!! theres your problem... your alternator should only be charging between 13.8 and 14.5 volts.... replace that bad boy before your blow something to smitherines (lol, i cant believe i just typed that in there)

they can load test your alternator in the car... then you shut it off and they can test your battery as well.

 

tiiiiiight

will do

 

ok now what if it is pushing to much?

 

replace it.

 

noooooooooooo lol

&lt;-- - poor

 

This happened to me a few years ago. There is a voltage regulator inside the alternator itself that's probably cooked. As far as I was told, the voltage regulator is built-into the alternator and cannot be replaced - the entire alternator will need to be rebuilt or replaced. My guess is that the voltage regulator CAN be replaced, however, you'd need to take the alternator out ANYWAYS, and the cost of labour taking one of those things apart and replacing that one piece, you might as well get a complete replacement so that you won't have anymore problems for a while.

the voltage regulator is a sealed unit. as is the alternator. correct me if im wrong.

NO! They will probably give you the wrong information. They told me I needed a new alt. when all I needed was some connections cleaned.

that has to do with the idiot that tested your alternator. any moron can tell the first things to check are connections. never ever jump to the alternator being bad on a on-car test. always start with the simplest stuff.

autozone tests them for free, just take the numbers and use that to start troubleshooting.
