6 PCS 9038 Relay Bypass Switch, Relay Tester with Amp Loop, Fuel Pump Bypass Kit for 12V DC Motors, Compatible with BMW, Audi, Chrysler (Black)

1.This 9038 relay bypass switch is a diagnostic tool that lets you manually control a car’s electrical circuit. It’s perfect for testing components like the fuel pump by bypassing the original relay.2.The built-in amp loop is a major advantage. You can clamp a meter around it to read the current, helping you diagnose if a motor is drawing too much or too little power.3.Built tough for shop use, it handles high current loads. You can safely use it to run 12V motors directly during your tests or troubleshooting.4.It is designed to be compatible with many vehicle makes, including models from BMW, Audi, and Chrysler that use standard relay sockets.

• Independent Circuit Control: This 9038 relay bypass switch allows you to directly control a circuit, like the fuel pump, independently of the vehicle's main ignition system. This function simplifies diagnostic testing by providing a straightforward method to power components and check for proper operation.
• Integrated Amp Loop for Current Monitoring: A key feature of this relay tester is its built-in amp loop. This allows you to easily use a clamp-on amp probe or a lab scope to monitor the current draw of the circuit you are testing, providing valuable data for accurate electrical diagnostics.
• Rugged Build and High-capacity Switching: Designed for durability, this bypass switch can handle up to 20 amps of continuous current and 30 amps of surge at 12V DC. This robust capacity makes it suitable for running various 12V motors and components during testing or temporary bypass applications.
• Wide Application for Specific Vehicle Systems: This versatile bypass switch kit is designed for use on automotive circuits that use standard relays. It is suitable for testing systems like fuel pumps, cooling fans, and window motors in compatible vehicles, including many models from BMW, Audi, and Chrysler.
• Plug-and-play Installation: Installation is quick and tool-free. Locate and remove the relay you want to test. Simply insert this bypass switch into the empty relay socket and use the manual switch to control the circuit.
