How to Troubleshoot like a Car Electrical Specialist

Troubleshooting an electrical problem tends to be a frustrating experience, but don’t worry. You might blow your temper, but since cars use DC (direct current) you won’t get more than a tingle of a shock, even if your shoes are wet and your standing in a puddle. (Unless you’ve got a hybrid or electric vehicle, in which case it’s safer just to take it to a professional.) And you don’t need to be a car electrical specialist to self-diagnose basic problems, though it helps. And you may need to call a professional anyway once you suspect what the problem is.

Check Your Circuits for Electrical Problems Before Calling an Expert

The first step is to check for the presence of voltage at the load point of a circuit, the element that the circuit is supposed to power. Use a voltmeter or a 12-volt test light that glows when there is voltage. If no voltage, check the circuit box. Use a 5- or 10-amp fuse to check the circuit until you’ve found one that works. Then you’ve isolated the problem. If you are still unable to locate the problem, contact a professional mechanic who specializes in vehicle electrical problems. They can run some diagnostics to quickly get to the heart of the problem.

The Sensitive Needs of Porsche Brakes

Unlike most domestics, brakes on your Cayenne Porsche have rotors with a minimal thickness to save on weight. This helps give the car that lightweight speed that’s great at turning corners. But that means they cannot be turned. They must be replaced outright. Their lightness also makes them susceptible to warping from intense heat. Coming in second to wear and tear, overheated brakes are a common reason the brakes will need replaced. Because the brakes are so susceptible and sensitive, they should be inspected every six months. Schedule an inspection regularly with your mechanic before you have a problem.
