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. WebMay 6, 2024 · The answer, in the case of a current-limiting resistor, is, in many cases, no. There is no practical difference between these circuits: +5v -> LED -> Resistor -> GND …

WebJul 1, 2006 · The sensor uses three wires: one 5-volt reference, one ground wire, and one signal wire that will also have 5 measurable volts found on it if the sensor is disconnected. The voltage found on the signal wire comes from the 5-volt reference through a 4.7K ohm resistor that links the signal lead to the reference voltage lead inside the PCM.

WebMar 6, 2024 · Some resistors have contact plates on the bottom. [5] 2. Read the 3 or 4 numbers on the resistor. The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow. For example, a resistor reading 1252 indicates a rating of 12,500 ohms or 1.25 kilo-ohms. [6] WebThe low threshold for acceptable resistance to ground is typically 100 megaohms for motors below 1000 volts. That’s a lot of resistance. It’s not however a magic number, below …

As I suspected, all the grounds are connected together at the power supply board, so the whole system and all boards have single point star ground. For example, the CHAN-GND only connects to J44-1. The other signal grounds are also at other pins of J44. POWER-GND only connects to J43-6.
WebDec 6, 2010 · In simpler language: the voltage (V) across a resistor is the current (I) through the resistor multiplied by the resistance (R). Here’s a simple circuit diagram to illustrate this: The symbol on the left is a battery, or a source of voltage. Since this is a car, we’ll just assume it’s 12 Volts.
