Hey Melinda==Check to make sure there is a good ground between the engine and body with no paint or dirt. Also remove both battery cables and clean both ends. This should do it. GoodluckJoe

Maybe a loose wire or a bad connection to the headlight itself.

There may also be a security function that has been triggered by the battery being unhooked during the alternator installation. My Jeep does this every time the battery is reinstalled in the circuit or is drained and recharged. I must then reset the security to get it to function properly. Good Luck finding the problem & hope this was helpful, Joe.

On a 1999 GEO Tracker, a bad fuse can cause the headlights and dash lights to blink. A bad voltage regulator or alternator can also cause lights to blink and flicker.

A loose or corroded ground wire can cause your 1995 Jeep headlights to blink on and off. Make sure the ground wire is tight and free of corrosion.

usually the squealing is from the alternator or the alternator belt in most cases it is the belt try to tighten it or replacing

If the alternator is bolted on too tight on its bracket,then it will cause the alternator to have a "bend" so that the clearance between the moving parts is reduced and the moving parts eventually jammed.

yes. to much corrosion on terminals can cause this. if your car starts right up after sitting all night, chances are your alternator is OK. clean terminals.

is your battery in good condition and fully charged? is your starter good?

when you use any kind of electrical component in your vehicle, it draws power from the battery , which in turn the alternator replaces.... you might want to get your alternator checked at your local autozone / advance auto as it might not be generating the output needed...this is the usual case...a simple test you can do is start your car... disconnect your positive battery cable...if the car stays running turn on your headlights, radio , wipers, and if the car stalls out... your alternator needs replacing....( note the fact that in most every vehicle...there will be some "dimming" of lights when you use electrical components....)

YES ! ! ! next you know you will be stranded trying to get a jumper it doesnt work until you replace either alternator and battery[both].

Hey John==Make sure the alternator belt is tight. GoodluckJoe A Bad Diode in the Alternator will cause the light 2 stay on & still charge the bttery.

This problem could be caused by a problem with your alternator. It may also be an electrical or wiring issue. It would probably be best to go to a mechanic to find and fix the specific cause in your case.

When replacing bulbs, do not touch glass part with your fingers. Any oil from your hands will cause shorten lifespan.

yes cause your eyes have muscles in them so u can blink

1 battery,#2 alternator,#3 headlights.In that order.One of them needs replacing.AnswerYou need a new battery.How long has your battery been in your car.If its more than 4 years,its done its time.If you've done that,check and see if your headlights strobe weak and stong when you step on the gas peddle and rev your engine.If they do,you need a new alternator.If you've done that,you should put new headlights on your car.If that doesn't do the trick.I'm out of ideas.Try these things in the order that I've described.

alternator may be bad causing to much juice....check it first. You may have a wire touching metal also near the headlight harness

The alternator may be failing. Drive to your local auto parts store and they can test the charging system for you for zip.

battery light on 2000 f250 will blink if battery is not properly charged. an example is if you have been sitting all day with stereo olaying and engine not running, you have run battery down some. after starting engine and driving, the battery light will blink while alternator charges until battery is fully charged i have only experienced this at night when lights are on creating extra load for alternator ,after running battery down with stereo all day

The Fuse Box can be located on your left hand side underneath the steering column...that useually requires a large fuse 20 or 30 plus I can answer the alternator question - yes, it causes alot of wacky wiring symptoms! The speedometer might stop, the indicator lights may blink fast, the "D" light may blink...etc.. Sorry can't answer about the fuse - but maybe in the fuse box!

all cats blinks it's just that they dont blink that much cause they always sleep

It sounds like the low beam/high beam switch is bad. Fuses are not the problem since they are built into the headlight switch and would cause headlights to blink or not come on for both high and low beam headlights.
