For the sake of simplicity, we’ll just refer to it all as “electrical interference” and get right to diagnostics. Any problem that involves any of these frequencies is referred to as Radio Frequency Interference (RFI). A subsection of the entire electromagnetic spectrum is the slice of frequencies referred to as the radio spectrum. Opposite of EMC is Electro Magnetic Interference (EMI), which is the science behind fixing the lack of compatibility. EMC engineers even take into consideration the static electricity (ESD) customers can create. ![]() A classic example of course is the use of resistor spark plugs/plug wires to combat AM radio noise and a diode across the A/C clutch coil to prevent the voltage spike induced when the compressor clutch coil is turned off from wreaking havoc on other electronics on the vehicle. Electromagnetic Compatibility (EMC) is the science of making sure every electronic component on a vehicle gets along with everything else including the occupants and their favorite gadgets. Starting out with a basic knowledge on this very tough topic is the first step. Center conductors from end to end should be 0.1 ohms or 3-4 ohms with the type using a smaller conductor on long runs such as the radio to rear back glass mounted antenna. The ground comes from the antenna’s end and should be less than 0.1 ohms. Always use the type the OEM used originally. In this article we’ll give you practical information on grounding, shielding and proper wiring so you can put an end to high-tech menaces like electrical transients, magnetic fields and Radio Frequency Interference (RFI) on vehicles you encounter.Īntenna coax varies in center conductor diameter and distance from the braided shield. It doesn’t have to be a complete frustration for you as a technician however. These are just a few of the problems that can occur in the world of electrical interference. Your favorite customer’s favorite FM radio station has static but only when the engine is running. The 2-way radio in the local game warden’s truck intermittently causes its transmission to downshift when the radio is used to transmit. Examples vary tremendously your road warrior customer drives past a busy airport each day and his cruise control kicks off. Phantom electrical problems caused by EMI (Electro-Magnetic Interference) while somewhat rare, can lead to a great deal of frustration, misdiagnosis and customer dissatisfaction. Sometimes the most intermittent and hard to diagnose electrical problems aren’t due to the classic faulty ground, computer glitch or software anomaly. ![]() Internal applications, then our B2B based Bizapedia Pro API™ might be the answer for you.Electrical problems can be tough.
