Health test for 4 and 5-pin electro-mechanical relays commonly found on modern vehicles. Test feature will cycle the relay 10 times, testing the resistance, contacts and consistency within each cycle. If a cycle fails on the test then this will be indicated by a red LED and alternatively a green LED if relay works.
