The VOLTCRAFT RT-100 automobile relay tester is intended for making fast and easy checks of most current automobile relays with 4 or 5 connections. The tester performs a full automatic check of the relay and indicates the result with a light (green = OK, red = error). The test is performed at the coil and contact side. Only one relay can be tested at a time. The automobile relay tester requires an automobile direct current of 12V to operate. This can be taken directly from the vehicle battery. The supplied pole terminals make connection to the vehicle battery easy. * Automobile relay tester * Runs from the vehicle battery https://elecena.pl/product/27162481/voltcraft-rt-100-car-relay-tester 2024-11-07 https://elecena.pl/product/27162481/voltcraft-rt-100-car-relay-tester 2025-04-12 https://elecena.pl/product/27162481/voltcraft-rt-100-car-relay-tester 2025-06-01 https://elecena.pl/product/27162481/voltcraft-rt-100-car-relay-tester 2025-09-08
