Universal Relay Buddy efficiently tests both 12 and 24 volt relays, quickly indicating whether therelay is good or bad. Its five test ports accept 7 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.
