Sounds Like Your Voltage Regulator Is Bad. This Is Inside The Alternator On Most Cars. You May Have To Remove It For A Test. But Lots Of Parts Houses Can Test Unit On The Car. Also Your Battery May Be Weak. Start With The Alternator First. Good Luck The alternator could be marginal. If one or more of the diodes are faulty the alternator will not be capable of producing enough current. You should be able to have the alternator tested at a local auto parts retailer such as checker, Kragen or Auto Zone. If a diode is faulty those tests can certainly detect it.
If you have no battery then you have no power.
Possible ground issue at the taillights.
Bad/shorted battery? (doesn't not hold a charge)
No, a starter cannot cause a battery to fail to charge. It could cause the battery to discharge quickly.
The most common cause for your 1997 Honda Civic lights to dim is a bad alternator. The alternator is not charging the battery. The battery retains a small charge, but not enough charge to run the engine.
Most likely a fuse.
A dead cell in the battery or something is on, such as the headlights. A stuck relay will also cause this. More likely than not, the battery has a dead cell and needs replacing.
A bad ground wire will cause dim headlights, or will cause lights not to work.
if you leave any lights on in the car you may cause you a flat battery. if you leave any lights on in the car you may cause you a flat battery.
Perhaps the alternator is bad, and the lights bring the battery voltage down too far. You could also have a loose connection at the battery.
A dead cell in the battery will cause it to loose it's charge overnight. The only fix is to replace the battery. Also if something is on drawing power from the battery it will run it down overnight. Look at all lights. Interior, under hood, trunk, give box, brake lights, etc. It can also be a stuck relay.
If the engine isn't running, the battery is low. If the engine is running, the alternator probably has a problem. If you are wearing dark sunglasses, remove them and the lights will get brighter. good luck!
leaving your lights on for a long period of time.. headlights or just playing the radio and leaving it play for a long time
The headlights place a larger load on the battery and cause the voltage to drop enough to dim other devices slightly.
probably the fuse is blown.
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
Turn on your headlights and try to sart the engine. If the lights go out the battery is probably bad. The contacts on the starter solonoid don't cause it to click.
A bad battery or faulty battery connection.
Headlights run off the battery not the ignition...
Dead cell in battery, replace it.
If you know it is the battery then try using a charger to charge the battery, make sure that you clean the battery connection terminals. If the battery will not take a charge from a charger then replace it, if a battery gets too dead it can't be revived. Also, have your alternator checked before driving if you didn't cause the problem with sitting or leaving the lights on etc.
Dead cell in the battery or the ignition or lights were left on.
a weak battery would most likely be the problem. if that doesnt work, have your alternator checked.
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.
