Abstract
A tester for a relay comprises an enclosure, a testing circuit that includes a controller, electronic switch components, a power source, indicator LEDs, a test start switch, a relay type switch, and five electric leads each connected with one terminal of the relay. With the relay type switch set to the type of relay being tested, with power supplied to each lead, and with the test start switch actuated, the controller can set each lead to ground, in turn, and then count the number of other leads that are grounded as a result. The controller then illuminates the at least one indicator to indicate either the passing relay test or the failed relay test based on the counts measured. Once the leads connected to the relay coil are identified, cyclic testing of the relay can be performed.
