Automotive Relay Tester and Bypass Jumper Set

FEATURES

INDEPENDENT CIRCUIT CONTROL – Take charge of the fuel pump circuit, bypassing the vehicle’s key-on system. This allows for precise and simplified fuel injection pressure testing without needing to turn the ignition.

INTEGRATED AMP LOOP – Features a convenient red wire loop designed for easy current monitoring. Simply attach a clamp-on ammeter or lab scope to accurately diagnose parasitic draws or excessive current consumption in the circuit.

PLUG-AND-PLAY OPERATION – Installation is effortless. Just remove the original relay and plug this bypass switch directly into the socket. You gain immediate manual control over the circuit with a simple flip of the switch.

ROBUST POWER HANDLING – Engineered to handle up to 20 amps of continuous current and a 30-amp surge at 12V. This makes it perfectly suitable for running various automotive DC motors and high-load components safely.

VERSATILE DIAGNOSTIC TOOL – This comprehensive kit is not just for fuel pumps. Use it to test and operate cooling fans, window motors, headlight switches, A/C compressors, and many other relay-controlled automotive systems.
