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.

What would cause dash lights to dim when you turn on headlights?

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....)

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!

Why would Using your Headlights Drain the Battery?

If your electrical system is working as it should, using your headlights will not drain the battery. Of course that is assuming your engine is running. More than likely your alternator is not putting out enough voltage to keep the battery charged with the headlights on. Take your car to a trusted mechanic or auto parts store and have your charging system checked. You may need a new alternator. A loose drive belt can also cause this so make sure the belt is in good working order and adjusted correctly.

Why dont your high beams turn on but your low beams both work on your 2000 ford expedition Is there a fuse for it?

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.
