13-PIN Trailer Plug Socket Tester
13 PIN Trailer Plug Socket Tester
The 13 PIN Wireless Trailer Plug Socket Tester is a practical diagnostic tool that allows you to quickly and precisely check the efficiency of the electrical system in a vehicle and trailer equipped with a standard 13-pin plug. The device allows you to check the correct operation of the lights without the need to involve a second person. The tester is connected directly to the trailer socket in the car or to the trailer plug, and the result of the operation is presented using LED diodes assigned to individual circuits.
At the push of a button, the device analyzes individual electrical circuits, such as position lights, indicators, brake lights, fog light, reversing light, and permanent power supply and trailer battery charging . This allows for quick detection of faults in basic circuits responsible for the safety and visibility of the trailer on the road. The tester precisely indicates irregularities using LEDs, allowing for quick response and repair .
Regularly testing the trailer's electrical system is essential for road safety – for both the driver and other road users. A damaged harness or faulty lights can lead to accidents or tickets. The GMPTM4003 tester allows you to quickly identify the problem without having to visit an electrician, saving time and money.
The tester is ideal for use in workshops, diagnostic stations, transport companies and private trailer users - both in everyday use and before a longer trip, technical inspection or trailer rental. Its small size and ease of use make it an irreplaceable tool in every trunk.
Advantages:
- quick and easy diagnostics of the 13 PIN socket
- error indication using clear LEDs
- ability to test both the car socket and the trailer plug
- compact and lightweight design
- perfect for home and professional use
The tester is powered by a 9V battery (not included).
