Why Did My Porsche Inverter Stop Working?

The Porsche dashboard gauges tell a clear story about the car, from the state and health of your engine to the rate of speed, as well as if your headlights are switched on. It is true that different vehicles have different gauges, but some instrument panels are found to be more complicated than others. However, the moment the gauges in your car suddenly stop working, it derives a situation that you cannot afford to ignore. Normally, the problem might be in the gauge or a faulty sensor when one gauge fails.  So why does this happen? Like you’re about to find out, the problem could be none of the gauges work, a single gauge doesn’t work or simply one or more dashboard warning lights don’t work.

None Of The Gauges Function

Of course there are a many different types of instrument configurations and cluster designs, but in a situation where all the gauges in a Porsche car stop working, all at once, the problem is usually associated with a wiring or fuse problem. You should first diagnose the issue to locate the fuse associated with the gauges or the instrument clusters. The requirement is that the fuse should have power when the ignition is turned. You can solve this by checking for power in the fuse with a multimeter or an inexpensive test light.

In the event the fuse is in good shape, you will want to check for power at the individual gauges. This mostly demands removing of the instrument cluster, of which it can be time consuming and difficult in some vehicles since it calls for a lot of precision. At least, you will most likely be compelled to do away with trim pieces and even unscrew the cluster in order to pull it free.

One Or More Dashboard Lights Don’t Function

In many cases, when only one light or gauge seizes to work, the problem is usually a bad gauge or sensor.  This might affect the whole Porsche gauge system since the problem can be as a result of failure in one of the fuses in relaying power to the gauge sensors. First locate the gauge or sensor that may have failed to work, and then make sure to disconnect the gauge or sensor. Now, depending on how the gauge operates, connecting the sensor to the ground, or disconnecting it, might allow you to examine the functioning of the gauge. In some cases you may learn that the problem was as a result of a loose connection.

 Both The Indicator And Dash Lights Failed

A clue that there may be an issue is when your dash lights, your gauges and indicators fail all at once to illuminate. This is in the assumption that you have already confirmed that the fuse of the gauge are in good working condition. If an instrument cluster is not grounded properly, you will find that the dash light and gauges fail or only function partly. You will be prompted to remove the instrument cluster severally to be able to check the ground with the aid of a flashlight.
