6-Piece Set 9038A Relay Bypass Switch Tester Kit With Wires For Electrical Testing

1. Powerful Functionality: This relay bypass switch independently controls the fuel pump, bypassing the "key on/off" system, simplifying fuel injection testing.
2. with Amplifier Loop: The 9038A relay bypass switch can be used with a clamp-on amplifier probe/lab scope to monitor current.
3. Plug and Play: Simple installation – mounts vertically or horizontally; simply plug into the fuel pump relay socket for direct control of the fuel pump circuit.
4. Operating Range: Handles up to 20A continuous current, 30A surge (12V); operates all automotive 12V DC motors via the rocker switch.
5. Wide Applicability: The relay bypass switch kit is suitable for most fuel pumps, cooling fans, window motors, headlight switches, AC compressors, and other devices using automotive relays.
