Charging and electrical systems, particularly on modern cars, are the most intricate and complex systems on your vehicle. It takes highly trained technicians armed with the right equipment to properly diagnose and repair electrical issues on today’s automobiles. Dennis Johnson's Auto Repair in Madison has the mechanics and the tools you need to get the job done right.
Your charging and electrical systems are deeply intertwined and are far more complicated than you might imagine. While batteries, alternators, fuses, and wiring operate under the same basic principles they have on cars for decades, there are a lot more details attached to modern cars.
Batteries were once primarily used for starting a vehicle; as long as your car started, you were in good shape. These days, batteries do a lot more than that. They act as a capacitor, for example, and a bad cell or a weak battery can cause all kinds of electronic malfunctions. Sensors and equipment that require steady voltage will trip warning lights or cause odd behavior of vehicle electronics if a battery needs to be replaced.
Alternators no longer simply spin and generate power, they too have a more complicated role. Typically, information fed through the ECU and an array of sensors communicate with the alternator, telling it to switch on and off and how much power to provide. A perfectly fine alternator can fail to operate correctly, because of something as simple as a blown capacitor inside the car’s computer.
The bottom line is, in a world of ever increasing complexity concerning your vehicle’s electrical systems, expert mechanics are now a necessity rather than a convenience.

Signs of Electrical System Problems
How can you tell if it’s your vehicle’s electrical system or some other component that needs repairs? It can be tricky to pinpoint an electrical problem, but there are some signs you should be on the lookout for:
- Your vehicle won’t start, and when you turn the key, you hear nothing – no grinding or clicking noises.
- Your vehicle is running just fine, but your headlights dim when you’re idling or driving slowly.
- The dashboard or interior lights do not illuminate or are very dim.
