What Caused the Charging Lights After Puddle Splash?

The Problem

The vehicle owner reported that after running through a puddle, the charging lights came on and the command sensor stopped working.

What We Found

The technician found that the alternator was not functioning properly, likely due to water damage from the puddle.

The Fix

The team performed an initial assessment at no charge and determined that the alternator assembly needed replacement. They removed the faulty alternator and installed a new one to restore the vehicle's charging system.

The Result

After replacing the alternator, the vehicle's charging system operated normally, and the command sensor function was restored.

Pro Tip

Running through deep water can damage your vehicle's alternator. Avoid puddles when possible, and if you notice warning lights afterward, have your charging system checked promptly to prevent further issues.

FAQ

Alternator Repair in Winter Haven: questions answered

Answered by our licensed technicians serving Winter Haven.

How do you tell an alternator problem from a battery problem?

The battery has to start the car. The alternator has to keep it running and recharge the battery. We test each separately, then measure charging voltage with the engine running and the electrical load turned up. A car that starts fine but dies while driving is pointing at the alternator, not the battery.

Why do you check the belt and the cables first?

Because they fake it convincingly. A glazed belt, a weak tensioner, a corroded cable end, or a bad engine ground will all drop charging voltage and produce the same dash light and dim headlights. Those are quick to check and much cheaper to fix, so they get ruled out before we quote an alternator.

Is it safe to keep driving with the battery light on?

Plan on the car stopping, and not at a convenient spot. Shut off the radio, air conditioning, and anything else you do not need, and drive straight to a shop or have it towed. Once the battery is drained the engine stops, and on most vehicles so does the power steering assist.

Do I need a new battery too if the alternator failed?

Sometimes, and sometimes not. A battery that has been deeply drained several times can be permanently weakened, but plenty of them test fine after a proper recharge. We test it and tell you what it shows instead of bundling one in automatically.

Can an alternator be repaired instead of replaced?

On most vehicles on the road today, a new or remanufactured unit is the practical repair, and it is what our warranty covers. If a pulley, belt, or connection turns out to be the real fault, that is what we fix. We will tell you exactly what we are quoting and why before anything comes apart.
