Web6 de jul. de 2024 · 15 How do you check the resistance of a coil? Do I need a resistor for my coil? And while ignition coil life may be compromised without a resistor, the additional secondary voltage (at the spark plug) is increased which generally improves power. WebThe coil is the part of a car’s ignition system that takes the battery’s 12-volt output (called low-tension current) and transforms it into as much as 45,000 volts (called high-tension current) before then supplying it to the engine’s spark plugs. It is typically just a wire-wound transformer filled with an insulator.

Then hold the negative wire and touch it to the mounting place. You’ll see the resistance on the multimeter. It will be around (2500 – 5000 ohms) 2.5 to 5 in the multimeter. If it’s low, like 1.7, or high, like 6.8, the ignition coil isn’t working, and you need to change it. cindy crawford face care line
