#192 DIAGNOSTIC RELAY BUDDY(R) 12/24 - Electronic Specialties

The Electronic Specialties #192 DIAGNOSTIC RELAY BUDDY® 12/24 is a professional-grade tool designed for the accurate testing of both 12V and 24V automotive and industrial relays. Utilizing the vehicle's own battery for power, this robust tester performs true loaded contact tests to effectively pinpoint relays with intermittent or high-resistance faults that might be missed by static checks, thereby enhancing diagnostic precision for technicians.

Key Features

• Broad System Compatibility: Accurately tests common 4-pin and 5-pin ISO mini relays found in a wide range of vehicles and equipment, including passenger cars, light-duty and heavy-duty trucks, buses, and agricultural machinery.
• True Loaded Contact Testing: Applies an operational load to relay contacts, enabling the detection of hidden voltage drops, high resistance, and intermittent failures under conditions that simulate real-world operation.
• Clear Go/No-Go LED Indication: Provides immediate and unambiguous feedback. A green LED indicates a functional relay, while a red LED, along with specific flash codes, identifies coil, contact, or internal faults. Trouble code definitions are conveniently printed on the back of the tester for quick reference.
• Automated Multiple-Cycle Routine: Conducts repeated relay cycles to effectively identify intermittent issues that may be related to heat or vibration, ensuring comprehensive and reliable testing.
• Convenient Off-Vehicle Testing: Allows for quick "off-the-car" bench testing, which helps optimize the use of valuable vehicle bays and other diagnostic equipment.

Applications

The #192 DIAGNOSTIC RELAY BUDDY® is an indispensable tool for diagnosing relay problems within critical circuits such as engine management, fuel delivery systems, radiator and condenser fans, HVAC blowers, and various lighting circuits. Its capability to pre-confirm component integrity helps professional repair shops and fleet maintenance operations minimize costly vehicle comebacks and reduce downtime, making it a valuable addition to any mechanic's toolkit.
