Dim Porsche Lights – 4 Reasons Why Your Alternator Could Be The Problem

Your Porsche’s alternator supplies your Porsche’s electrical needs. So the moment it begins to lose its potential, all car accessories that rely on it to draw electricity fail.  That is one of the main reasons why your Porsche may begin to exude erratic symptoms that range from extremely bright dash and headlights to dimming or completely blown out headlights. The problem may then extend to tachometers and speedometers.  All these can happen because of a faulty alternator. But why in the first place does the alternator fail? The following reasons explain why.

The Condition Of Your Alternator

The strength, contrast or brightness of your Porsche’s lighting components will always depend on how well the alternator produces power. It will also depend on the stage of death cycle the alternator is at. Other factors such as how your Porsche is programmed can also determine how well your lighting components and the alternator coordinate. New Porsche models come complete with a set of pre-programmed software where power will be sent in just in case the alternator fails. This is only temporary though and is often based on safety considerations.  It is one of the main reasons why your Porsche’s heated seat will turn off before the headlights dim and eventually fade away.

The Alternator Is Not Generating Enough Power

Dim interior and exterior lights are good signs of alternator trouble. Your Porsche lights might also flicker from time to time. These two symptoms usually go hand in hand. Your Porsche lights could be dull, bright then dull again at random or on a regular beat.  This can only mean one thing – that the alternator is not generating enough power to keep your Porsche lighting components at full strength. So instead of dimming all lights, the alternator is trying and failing to churn and maintain the right lighting output.

The Car Battery

There is always a direct link between the strength of your Porsche lightening components and the strength of the car’s battery.  The alternator also gets involved at some point. Each time the alternator fails, the battery takes some slack instead of acting as a capacitor. The battery therefore fails to receive a regular or constant infusion of electric charge from the alternator. In short, a faulty alternator will always get your attention by slowly killing the battery even where the battery was not the problem to begin with. Before you know it, the lighting component will dim or go off.

Faulty Cabling

Any problems with wires, cables and connections in general at either end can stop electricity or reduce it from getting through. More often than not, a symptom associated with this issue can cause brighter lights because the alternator ends up producing more energy so as to overcome the resistance in a faulty wire, loose or broken connection.  This symptom may or may not be accompanied by the smell of hot wires. To put this concept in perspective, higher resistance within a wire always creates heat. This happens the same way an electric burner on a cooking stove heats up by resisting seamless flow of electricity.
