AUTOMOTIVE_ELECTRICAL_TESTER

Published:2009/7/9 3:45:00 Author:May | From:SeekIC

This little tester is useful for checking vehicle electrical circuits. Two LEDs indicate whether one of the clips is connected to the positive supply line (red) or to ground (green). The unit is powered by the vehicle battery. It is advisable to terminate the unit into two insulated heavy-duty crocodile clips. These enable connection to be made directly to the battery or to terminals on the fuse box.It is also possible to terminate it into a suitable connector that fits into the cigarette lighter socket. If a sharp needle is soldered to one of the terminals, it is possible to check insulated wiring-but only those that carry 12 V. Although the needle pierces the insulation, it does not damage it.
