Electronic Specialties' Relay Buddy Pro Test Kit, No. 191, includes five newly developed relay adapters and a tester, in a blowmold case. Three of the adapters make possible testing of shielded relays while the other two adapters permit testing of two new relay types commonly used on fuel pumps and other powered devices. The tool checks the control side of the relay by applying a signal to the relay coil while it checks for proper functioning of the relay contacts. It will fail the relay and illuminate the red LED if any one of the cycles proves unsuccessful during the test session.
