Volkswagen Battery Test

Best Repair Center in Modesto for Handling Volkswagen Battery Charging Issues

Is your Volkswagen failing to hold a charge or does it seem to die on you out of the blue? Volkswagen cars are among the best in the market and boast great engineering, but any car on the road, whether well-engineered or not, may develop battery charging issues at one point or another. It is important to solve the cause and diagnose battery charging problems in Volkswagens accurately, so the problem doesn’t recur or you don’t have to prematurely replace the battery. Continue reading to find out how to correctly diagnose and repair charging system malfunctions in Volkswagen and where to take your vehicle if you are faced with this problem.

How to Identify Battery Charging Problems

  • Test the Battery Voltage: You can know the voltage of your battery with the help of a multimeter. Just make sure you turn off the engine first, then use the multimeter to check the voltage. If the reading is low, it means that the battery is not able to retain charge in the best way possible.
  • Check the Alternator Output: When the engine is running, perform a test on the voltage across the battery terminals. The voltage should be above 5 V. If it’s lower, this simply means that the alternator is not charging the battery adequately.
  • Inspect Battery Terminals: Now look at the battery terminals; are they corroded or loose in some way? If the terminals look dirty, then clean them and make sure that the connectors are making good contact.
  • Look for Parasitic Drain: If your battery loses power while the car is off or parked, it might be time to check for a parasitic draw. A mechanic can perform a parasitic draw test if he/she wants to know if there is a high drain on the battery.
  • Test the Voltage Regulator: There are many cases where the alternator is supplying power, but the battery is not charging as required. In this situation, the voltage regulator is likely to be the issue. Subjecting the regulator to tests will be a good idea, as it will verify whether the correct amounts of power are being sent to the battery.

How to Solve Battery Charging Problems

  • Replace the Alternator: If the alternator is the problem, replacing it will solve the problem in the charging system. A mechanic is capable of identifying the problem, and if necessary, replacing the alternator.
  • Clean or Replace Battery Terminals: Charging problems can be caused by loose or corroded connections. Cleaning the battery terminals and making sure there is a tight connection can solve this problem. In some cases, the terminals may be badly corroded and might need replacement.
  • Install New Battery: If you are using a battery that has been with you for years or if you have a low-quality battery, then having it changed may help to eliminate most charging problems. Be sure to get the best battery that suits your Volkswagen model.
  • Repair Parasitic Drains: Any parasitic drain must be located and corrected in order to prevent continuous power loss from your battery. This may include the correction of wrong wiring connections or the replacement of faulty parts that continue to pull current when the car is not in operation.
  • Replace the Voltage Regulator: If the voltage regulator is damaged, then you will have to replace it to ensure the normal flow of electricity from the alternator to the battery.
