Test and Diagnostic Equipment for Automotive Electrical Systems

Electrical faults in a vehicle can range from a dead battery or a broken wire to faulty ground connections, increased power consumption, or problems with trailer outlets. For reliable troubleshooting, it is therefore crucial to select the appropriate measurement method for voltage, current, resistance, continuity, and electrical supply.

Leitenberger Automotive Test Equipment offers professional automotive test lamps and multifunction testers, multimeters and current meters, testers for battery and charging systems, as well as tools for diagnosing open circuits and short circuits. In addition, electronics and surge protection devices, solutions for emergency power supply and voltage maintenance, glow plug testers, and testers for trailer lighting and towing vehicle sockets are available. Depending on the model, the systems are designed for 6-, 12-, or 24-V vehicle electrical systems and various workshop applications.

When performing electrical work, a distinction must be made between conventional low-voltage vehicle electrical systems and the high-voltage systems found in electric and hybrid vehicles. Testing and safety equipment for high-voltage applications can be found separately under Electrical Safety in the Alternative Drives / E-Mobility section.
