Health test for 4 and 5 pin electro-mechanical relays commonly found on modern vehicles. Test feature will cycle the relay ten 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 the relay works. Supplied in zipped pouch.
