Overview
Car Relay Tester 13.9 x 6.3 x 2.7 cm RT01 for 4-pin and 5-pin Relays with Battery Voltage Display 11 to 25 V Black and Yellow

The RT01 car relay tester is used for quick checks of automotive relays with four or five pins and simultaneously measures the battery voltage. The relay is inserted into the socket on the front, a switch selects the 4 pin or 5 pin mode, and after pressing the TEST button, the relay tester automatically evaluates the result. The result is indicated by a light under the socket: a green light means the relay is functioning correctly, while a red light indicates a fault. The device is powered directly from the car battery via a pair of crocodile clips, so it does not require its own batteries. The red digital display at the top shows the battery voltage in the range of 11 to 25 V, making the tester suitable for both 12V and 24V vehicles.

  • Relay Socket – the front side has marked positions for standard automotive relays, and the diagram of the contact layout facilitates the correct insertion of the relay.
  • 4PIN and 5PIN Switch – the sliding switch at the bottom left determines whether a relay with four or five contacts is being tested. The tester is designed for relays with coil resistance of 20 Ω and above, which corresponds to common relays used in passenger and utility vehicles.
  • One-button Evaluation – after pressing the TEST button, the check is performed automatically, and the result is immediately apparent from the colour of the DEAD/GOOD indicator, without the need to measure individual contacts with a multimeter.
  • Battery Voltage Measurement – after connecting the clips, the display shows the current battery voltage, so the tester can also be used for a quick check of its condition, for example, before winter or when the vehicle has trouble starting.
  • Crocodile Clips – the red and black clips are firmly connected to the tester body, the cable measures 42 cm and the jaws open to approximately 2.1 cm, allowing them to be attached to standard battery terminals.
  • Dimensions – the tester body measures 13.9 x 6.3 x 2.7 cm and fits into a toolbox as well as into a car glove compartment. The clips with the cable can be easily wrapped around the tester body for storage.

  • 1x relay tester with crocodile clips

The RT01 tester is a useful tool wherever the radiator fan, horn, lights, fuel pump, or other appliance switched by a relay stops working. Instead of blindly testing spare parts, simply remove the relay from the fuse box, insert it into the tester, and within moments it is clear whether it needs to be replaced. Thanks to direct power from the car battery, the device is ready for use at any time without the need for recharging or battery replacement. It will be appreciated by garages, auto electricians, and drivers who carry out minor repairs themselves. The black body with a yellow control panel and clear diagram of the contacts makes orientation easier even when working in poorly lit garages.
