Can an automotive resistor have 4 grounds
WebAnything over .3 ohms is going to cause problems. Most problems can be determined by process of elimination. Start by checking fuses—if the fuses check out, then check what the wire is controlling (e.g., light, sensor, motor). Next, check the circuit to make sure the wires are not damaged and have good continuity. WebFeb 7, 2024 · The automotive ISO mini relays we have been looking at above are typically available in two types of pin layout designated Type A and Type B layouts.
