Relay Buddy 12/24 is a quick go / no-go tester for the most common automotive relays. This new version Relay Buddy tests both 12 and 24 volt relays. If the relay fails the test, 3 different trouble codes will advise you of the possible causes for the failed relay. In kit form, #193 Relay Buddy 12/24 tests 5 different relay types. Relay Buddy 12/24 provides you with an indication of the general health and functioning of the relay switch contacts and coil. It will check the control side of the relay by applying a signal to the relay coil while it checks for proper functioning of the relay contacts. Relay Buddy operates the relay several times during each test session as it watches for consistency in every cycle. Relay Buddy will fail the relay and light the RED LED if any one of the cycles proves unsuccessful during the test session.
