Several simple steps may help your service personnel preserve costly diagnostic test leads. Here's how.
Test leads are the specialized wires and cables that connect various types of diagnostic testers to a vehicle with a conventional electrical system. These testers include everything from a common voltmeter to an oscilloscope or scan tool.
Competent diagnosticians would agree, I'm sure, that the tester at hand is only as good as the leads connected to it.
Maintaining and preserving test leads make dollars and sense because the accuracy of the tester depends upon the quality and condition of its test leads. What's more, replacing test leads can be very expensive.
Predictably, some diagnostic test leads are hardier than others. High-quality leads can withstand automotive lubricants, chemicals and physical abuse much better than cheap ones.
But that said, it still pays to keep all test leads away from lubricants and chemicals as much as practically possible. Inevitably, test leads become dirty, oily and/or greasy.
All too often, I've seen technicians try to clean test leads with products such as spray carburetor or brake cleaner.
Experience shows that the harshness of these cleaners can vary a lot from one brand to another. Some of these solvent-like cleaners can dissolve a test lead's outer jacket into a sticky, useless mess.
