Have the Battery charged and tested to be sure its not over working the alternator.
could be the alternator is about to go out
your alternator is dead.
Well when you are driving the alternator is at a constant speed then when you slow down the alternator sort of skips a beat causing the lights to dim!
Defective alternator or broken alternator belt.
if the light get brighter when your driving then its your alternator so a new one will be needed
Have your alternator checked out.
Have alternator checked. There should also be other signs like lossing power to certain things or dim lights, if so...might be the alternator.
your alternator is going bad
Possibly the alternator.
sounds like an alternator problem
(no it uses the energy from the car battery not the energy made by the engine)Yes it does increase consumption because the battery has to be recharged by the power of the engine driving the alternator or the dynamo
Your voltage regulator is shot. It is integrated in your alternator. You need to replace the alternator.
Have your alternator tested. They will sometimes do that when they are putting out low outputs at low rpm.
Loose alternator belt, poor ground connection, or loose or corroded electrical connections. A loose ground is the most likely culprit.
The car will not start after driving for a period of time. The lights are very dim while the engine is running and get darker , or the battery light is on in the dashboard.
There are several signs that an alternator is going bad. A few signs are dim lights, smell, warning lights, and a dead battery.
Im assuming these turn of after startup. When the alternator isn't running, these lights automatically come on. Your alternator doesn't start running until your car is running, because it is run by a belt from your engine. So, if your lights stay on after startup, either you have a snapped alternator belt or your alternator is buggered. We had our alternator belt snap the other day while we were driving down a hill, it was quite a scary experience as we didn't know what was going on and in automatics the breaks barely work without the alternater running.
Check your alternator, if it is going bad, your dash lights will go on. This condition will last until the alternator finally fails completely, leaving you stranded. Go to AutoZone or Walmart automotive and have it checked.
Check for poor ground connection either at the alternator or follow the negative cable coming from the battery.
have the alternator checked sounds like an imtermittent problem that shows the alternator has a bad diode replace it soon or at sometime when driving with lights on,you will be stuck until daylight when you can drive without lights
Turning the lights on put a load on the alternator causing the idle speed to drop. I would have the battery and charging system tested to make sure everything is okay. The battery may be on its way out.
your alternator was never the problem. Its your battery and/or charging system. the reason the lights get brighter is because the car isn't getting the propper amount of energy from the battery and is having to directly draw off of the alternator. when the engine is rev'ed the alternator spins faster creating more current to charge the battery, witch is why the lights brighten at higher rpms.
If you have flickering lights and smell wires burning in your Dodge Caravan, you need to get that checked out by a professional. This actually happened to me once too and my van started on fire, it was horrible.
