There are several possible reasons why your 1999 3.8 Firebird is experiencing voltage fluctuations and losing voltage randomly when driving with the lights on. Here are a few potential causes:
Alternator Issues: The alternator is responsible for charging the battery and powering the electrical system while the engine is running. If the alternator is failing, it may not be providing a consistent voltage output, which could cause voltage fluctuations and a loss of voltage.
Battery Issues: The battery could be old, weak, or not holding a charge, which could cause voltage fluctuations and a loss of voltage.
Electrical System Issues: There could be issues with the electrical system, such as a short circuit or a faulty ground connection, which could cause voltage fluctuations and a loss of voltage.
Loose or Corroded Connections: Loose or corroded connections in the electrical system can cause voltage fluctuations and a loss of voltage.
To diagnose the issue, it's best to have a mechanic perform a thorough inspection of the electrical system, including the battery, alternator, and wiring. They may use a multimeter to measure the voltage output of the alternator and the battery to determine if they are functioning properly. They may also check the wiring and connections for any signs of damage, corrosion, or looseness.
Once the cause of the issue is identified, the mechanic can perform the necessary repairs or replacements to fix the problem. This may involve replacing the alternator, battery, or other electrical components, as needed.
