Batteries: Your vehicle’s battery is used to start the motor by introducing an electrical current. Keeping your battery clean and in good condition is a must for proper vehicle use. If you are experiencing issues with starting your car, you may need a battery replacement. We can perform battery checkups and when needed, a battery replacement in sunrise.

A Dead Battery Does Not Always Mean You Need A Battery Replacement:
A car battery is responsible for powering the ignition system and starter. If you turn the key and your car won’t start, there is a good chance that the battery is dead. You may hear a clicking sound or hear it slowly turning over but never actually starting. Sometimes nothing will happen at all.

Dim lights while trying to start the vehicle indicate low voltage in the charging system. Low voltage can be caused by several different issues including an uncharged or bad battery, or an alternator problem. Just because the battery is dead, does not mean it is bad. Replacing the battery will not solve the problem if the alternator is not functioning properly. Dirt or corrosion on the battery terminals or battery post can also cause a bad connection, so always have a mechanic check this before replacing any parts.
Alternator Replacement in Sunrise fl
Your vehicle’s alternator is an A/C generator that serves two main functions. First, it is responsible for charging the battery while the engine is running. Second, it supplies the power which operates electronic components (such as lights, stereo system, power windows, navigation systems, etc.) while the engine is on. When the engine is not running, many of these components rely on power from the battery. This is why forgetting to turn off your lights often leads to a dead battery and a car that won’t start. Allowing the battery to drain completely may cause permanent damage to the battery, but most often simply jumping or charging it will solve the problem.
Some common signs that you may have a bad alternator include dim lights and slow or hard cranking. Your vehicle is also equipped with dashboard warning lights which may indicate a problem with the charging system. Keep in mind, however, that some alternator problems such as a bad voltage regulator can prevent the lights from functioning properly. Just because the warning indicator is not illuminated does not mean that there is not problem.
When your car’s battery light comes on, it may be because the battery is not maintaining a sufficient charge. It takes further diagnostics to determine whether the issue is simply a dead battery, a bad battery that cannot hold a charge, a bad alternator that is not sufficiently charging the battery, or even a problem with the ignition switch. The light will usually come on when the charging system is not working altogether. Complete charging system failure often indicates a broken alternator drive belt. Because starter problems, bad batteries, and bad alternators all have similar symptoms, these problems are easily misdiagnosed. Before having a battery or alternator replacement, be sure to have a certified technician determine the exact cause of your charging or starting problem.
Alternator Drive Belt or Serpentine Belt Replacement
It is a good idea to have the alternator’s drive belt checked periodically. This belt is powered by the rotation of the engine and drives the alternator. Many vehicles run on a serpentine belt which also drives other components such as the power steering pump, water pump, and AC compressor. Other vehicles use separate belts to drive each component. If the alternator belt is loose it reduces efficiency and runs down the battery. The drive belt eventually wears out or breaks and should be replaced according to the manufacturer recommended service schedule to avoid damaging components.
Voltage Regulator
The voltage regulator is responsible for regulating alternator output, or voltage. The regulator applies current to the alternator or stops applying current as necessary to maintain the ideal voltage range of 13.5 volts and 14.5 volts. If the voltage drops too low, there will not be enough power to run the necessary electrical components. If the voltage is too high, it can damage or “fry” the electrical components. On most newer vehicles, the voltage regulator is internal and is mounted inside the alternator housing. If the internal voltage regulator is bad, it is usually the most cost-effective to have the entire alternator replaced. Older cars and trucks (as well as some new Ford vehicles) have an external voltage regulator which is mounted on the outside of the housing and connected to the alternator by a wiring harness. A bad external voltage regulator can be replaced without having to replace the alternator. Before replacing any parts, the wiring harness should be inspected to eliminate the possibility of electrical issues.
Electrical Issues May Cause Charging Problems
Faulty wiring or bad circuits create electrical problems within the charging system. These can prevent the alternator from charging the battery properly even if both the alternator and battery are good. Auto Service Experts technicians have extensive experience in auto electrical repair & diagnostics. Before replacing the battery or alternator, we will ensure that the problem is not caused by an electrical issue.
The alternator generates AC or alternating current, but automotive electrical components require DC or direct current to power their operation. Within the alternator, there are 6 diodes connected to the rectifier assembly which work together to convert the AC current to DC current before it passes through the electrical system. A shorted diode will allow AC current to pass through the system which can create any number or combination of electrical issues within the vehicle. This can mean serious problems because many modern automotive systems are computer controlled.

Electrical Charging Diagnostics
The fuses in your vehicle protects components of your electrical system by limiting the amount of electricity flowing into each part. From a blown fuse to an entire fuse box replacement
A technician will connect an ammeter to measure the amperage (or the volume of electricity) which is being drawn from the charging system. The amount of draw on almost all vehicles should remain below 50 milliamps, however, the ammeter is showing a 397 milliamp draw. Although the vehicle is off and no electrical components are being used, a large volume of electricity is being drawn from the charging system. Under this condition, the battery will die out within a few days and will not hold a sufficient charge until the issue is fixed. The large amperage draw could be due to a problem within one of the electrical components such as the radio or lights, a short in the alternator, or any number of other electrical issues. Extensive electrical diagnostics are required to determine the exact cause of the problem and prevent it from reoccurring.
