Battery and fuel water light on,alternator overcharging


Don't know much about your vehicle but sounds like you may have an external voltage regulator...need to find out no matter how many alternators you change if the regulator is allowing too many Amps and voltage out..you could damage the entire charging system including the battery..confirm what your car has can checked to see if the alternator you bought has an internal reg also have your auto store go in computer an see if in deed you can order an external one for your car..if available you know it does have one or not.. But overcharge is all in the regulator..good luck..

I am trying to locate where the voltage stabliser is on my friends 1997 xj6 3.4l Jaguar can anybody tell me where it is ?


It is part of the alternator it is called a regulator. This regulate the voltage that charges the battery. If that regulator goes bad, you end up with overcharging which is dangerous and can blow up the battery, or you end up with a car that has a short and not charging.

Put a new alernater an still over charging


Over charging could be the result of several things including:
    Faulty Voltage Regulator
  1. A car's battery will overcharge if the voltage regulator isn't working correctly. A voltage regulator is usually part of the alternator, and is used to keep a steady flow of voltage to the battery. If the voltage regulator is defective, it will send either too little or too much charge to the battery. If it sends too much, the car battery will overcharge. The voltage regulator is easily replaceable at an easily affordable price, sometimes for as little as twenty dollars, as of 2009.
  2. Faulty Alternator
  3. Sometimes the alternator itself can be at fault. The alternator is the device that converts the mechanical power of the engine into electrical power to charge the battery. When an alternator breaks, it usually stops creating electricity for the battery, which will then eventually die. However, if the wrong alternator is placed in the car, or if the alternator is running at the wrong pace, it will create too much energy for the car battery, causing it to overcharge. The alternator is another easily replaced part.
  4. Incorrect Charger Use
  5. If a battery charger is used to charge your battery outside of your car, improper use of the charger can result in overcharging. If a battery is placed on the charger too long, it can result in overcharging, and a significant decrease in your battery's lifespan and efficiency. This is why it is important to read about your specific battery and understand how long it needs to charge to be effective. Too much charge will lead to problems.
  6. Faulty Battery Chargers
  7. Sometimes chargers can be faulty. Their settings may be wired incorrectly, or the charges labeled incorrectly. As a result, your battery may be getting overcharged, even if you are carefully monitoring your charging. This is a problem that is hard to avoid, as manufacturing mistakes can happen anywhere, anytime without warning. It is a good idea to test your charger regularly to see if it is running correctly.
  8. Heat
  9. Extreme heat in the summer can also have an adverse effect on the car battery. If the battery has been previously overcharged, extreme heat can increase the problems caused by overcharging, and exacerbate any other problems with the battery. This problem can be hard to avoid if you live in a warm climate. The only real way to ensure safety against this problem is to avoid overcharge in the first place.

My jeep is overcharging by the gauge


with a car that old its possible the gauge is off but to be sure you can go to autozone or pepboys im pretty sure they will test the charging system for free . or if you have a volt meter you can check it yourself it should be 14-14.8 with the car running anything higher than 14.8 is overcharging . if it is overcharging you will need an alternator for sure and if the battery is over 3 years old its best to replace that too so you dont break down in the near future because overcharging cooks the battery so whatever life it has left has been cut hope this helps

My 1987 dodge dakota is not holding a charge, altonator tested and good battery only a year old but have to push start it to get it to run and my lights are really dim


You need to bypass voltage regulator to be certain alternator is charging properly. When you full field alternator it eliminates voltage regulator. If it indeed is good it will overcharge. If it overcharges as it should when you bypass/full field alternator then the regulator, or its connection or the place it attaches to is rusty & wont conduct a ground.

My 93 jeep grand cherokee starts but it draws a lot of juice then it dies. So far I have replaced the fuel pump, starter, coil, ignition, and alternator. Any suggestions?


Based on what you noted, your system is not drawing too much, it is overcharging. Determine if you have an external regulator in your system (depends on alt. make and alternator design) Many of the Jeep systems have the voltage regulator as an integral part of the main computer. Likely it has failed. Also make sure that the charging system is properly grounded and the battery is fully charged and can undergo a load test without substantial voltage drop. If it cannot, it will over-work the alternator.

1991 jeep wrangler: alternator overcharging


It sounds as the voltage regulator which is built into the back of the alternator has stuck. Occaisionally this even happens on new ones. Would suggest taking the alternator back as it shoud be under warranty.
