Powerful: This relay bypass switch controls the fuel pump independently of the "key on/off" system, Simplifying fuel injection testing
With Amplification Loop: The 9038A Relay Bypass Switch can be used with a clip-on amplifier probe/lab oscilloscope to monitor current
Plug and Play: Simple installation, can be installed vertically or horizontally, just plug in the fuel pump relay position to directly control the fuel pump circuit.
Operating Range: Maximum 20 amps continuous, 30 amps surge (12V), runs all automotive 12V DC motors with the flip of a switch
Wide Applications: Relay Bypass Switch Kit fits most fuel pumps, cooling fans, window motors, headlight switches, air conditioning compressors and other devices using automotive relays
