Ground-side voltage drop, a commonly overlooked cause of electrical … 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.
WebAutomotive Wiring Basic Symbols. Automotive electrical diagrams provide symbols that represent circuit component functions. For example, a few basic symbols common to electrical schematics are shown as: (1) Switch, (2) Battery, (3) Resistor and (4) Ground.
