Why Won't My Relay Work at Bobby Reynolds blog

Why Won't My Relay Work. The most common symptom of a bad main relay is that you won’t be able to start your car, and nothing may happen when you turn the key. Explaining how relays work and how to test them. A relay may fail if it is exposed to excessive current or voltage, which can burn out the contacts or damage the coil. Every car has relays, but why? An intermittent power signal to any one relay may cause a rough running. Not to mention, the reverse bias flyback diode (d1,. Make sure the load, such as a motor or light, is functioning properly and not causing the relay to fail. It can also result in a stalling engine while driving, or warning lights on your dashboard. The main relay sends power to each relay for the ignition, fuel pump, and engine control unit (ecu). Most common relay failure reasons. There are several reasons why a relay may fail, including: The output side of the optical coupler and the transistor driving the relay only work when the current is passing in the proper direction. Inspect the relay for any visible damage or signs of wear, such as burned or corroded contacts.
