The Electronic Specialties Diagnostic Relay Buddy 12/24 Pro Test Kit, No. 193, includes five relay adapters, the Diagnostic Relay Buddy 12/24 tester and a blow mold case. Three of the adapters test shielded relays, and the other two adapters test two new relay types commonly used on fuel pumps and other powered devices. The tester is suited for 12V automotive vehicles, 24V electrical systems in heavy duty vehicles and 24V battery-powered equipment. A good test result is displayed as a green light, but if the relay fails, one of three programmed diagnostic codes will flash the red LED. The product, which has a one-year warranty, uses the vehicle’s battery for its power source and works with most common 4/5 Pin 12V and 24V relays.
