Can A Relay Be Intermittent at Alma Weathersby blog

Can A Relay Be Intermittent. Identifying relay failures and their causes enables you to fix problems quickly. Relays have finite life time in terms of how many times they can open and close. Relays that are used frequently can experience mechanical wear and tear, which can cause the contacts to wear out or the actuator to fail. The main relay sends power to each relay for the ignition, fuel pump, and engine control unit (ecu). Although it has a simple operating principle and structure, a relay can sometimes fail. The answer to that one is no. If you see readings fluctuating in the low ohms, the contacts are damaged and it's time to change it. The best you can state is the device is more likely to fail one way or the other under. A relay may fail if it is exposed to excessive current or voltage, which can burn out the contacts or damage the coil. These faults can be classified as mechanical and electrical. If you power it from a bench. An intermittent power signal to any one relay may cause a rough running engine or it may stall out and leave you stuck in traffic. This is good news, because relays can fail to open (contacts weld shut), but not usually fail to close (unless the coil has burnt out, which is easily. Generally fail open or fail closed is hard to be sure about.
