Suitable for various applications including relay coil resistance/relay contacts/cyclic testing. (Not suitable for later Ford 4-pin relay)
Colour coded performance indicator
Relay coil resistance 20-50 ohms
Relay contact resistance threshold 200 milliohms
Testing automotive relays can literally be a bit hit and miss, good connections and continuity do not always mean a serviceable component. This new diagnostic relay tester from Laser Tools (part no: 5562) quickly and accurately tests electro-mechanical relays on most modern cars.
Four and five-pin relays can be tested — sockets are included for the three most common relay types. The suspect relay is plugged in to the tester — the 12 colt power source from the vehicle cycles the relay ten times applying a signal to the relay coil while checking function of the internal contacts. The internal contacts are loaded to detect excessive resistance and the tester will fail the relay if one of the cycles proves unsuccessful.
It enables a quick and easy off the car relay test and is an indispensable diagnostic tool for the technician and auto electrician.
