Universal Relay Buddy 12V/24V

April 10, 2026

The Electronic Specialties Universal Relay Buddy 12V/24V is designed to efficiently test both 12V and 24V relays, quickly indicating whether the relay is good or bad. The five test ports accept seven of the most common relays in use. Universal Relay Buddy's internal circuitry sorts out the difference between SAE standard/bifurcated/two branch relays as well as that special green BMW/Mini relay with two 87 pins and pins 86/30 switched.
