What are the symptoms of a failed ignition relay?
One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
Where are the fuse panels on a Mazda RX-8?

Can a bad ignition relay cause a battery to die?
If the relay has an internal short it may keep power fed to the ignition and fuel system, even when ignition cylinder is in another position, or the key is removed. This will cause the fuel pump and ignition components to remain powered on, drawing current, at all times, which will eventually lead to a dead battery.

What are the pins on an engine relay?
Pin 85 and 86 are the coil. So we will hook one up to 12v, and one to ground. This way when the relay receives either voltage or is grounded the relay will jump into action. So when it does “jump into action” what will it do? Well in this case it will take whatever voltage is on input 30 and switch it from outputting on pin 87A to pin 87.
Where is the ignition relay located in a car?
It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle’s ignition system, and some of the fuel system’s components.
How are spikes generated in a relay coil?
Relay coils give off high reverse-voltage spikes that will destroy sensitive electronic components. These spikes are generated by the coil – when the relay de-energizes – and the coil’s magnetic field collapses. They are generally removed by fitting an external suppressor diode – across the relay coil. See diode D1 on this Repeat Timer Schematic.

How is pin 85 connected to the relay?
Once you do this, pin 85 receives 12volts and the coil energizes, flipping the relay from outputting pin 30 from 87A over to 87. Well it turns out 87 is hooked to your High-Beam lights. So what happens….your low beams turn off on pin 87A and your high beams turn on because of pin 87.

Can a bad circuit breaker cause intermittent power outages?
A faulty circuit breaker can also cause intermittent faults. Breakers contain a heat-sensitive bimetal contact arm and contact points to open a circuit if it overloads. After the circuit breaker cools down, the contacts re-close and current is restored. If the breaker is bad, it may be opening prematurely.

What happens when there is an intermittent electrical problem?
If an electrical component has failed, or there is an open or a short in a circuit, you can usually find it fairly quickly because it isn’t hiding from you. It’s a persistent fault that can be isolated by a systematic process of elimination. Not so with intermittents. Chasing intermittents is like chasing ghosts.
