WebIGNITION BALLAST RESISTOR PN 8214 BROWN GREEN RED NOTE: The purpose of an ignition ballast resistor between the ignition switch (12V) and the ignition coil positive terminal is to restrict current flow through the ignition coil. Failure to use an ignition ballast resistor will eventually destroy the Ignition Module. Web24 jan. 2024 · The ballast resistor reduces the ignition voltage down to the 8v whilst the engine is running – but during starting the ballast resistor is bypassed giving full voltage for a short period of time. In fact the full voltage whist the engine is cranking is about 10v not the normal 12v due to the battery having to work at maximum whilst starting the engine.

Web7 jul. 2024 · What is the purpose of a ballast resistor in an ignition system? The ballast resistor allows the ignition system to operate at a lower voltage until the engine starts. After ignition, the alternator begins to recharge the battery, restoring the regular voltage. What can cause a ballast resistor to go bad? Web3 aug. 2024 · A ballast resistor, connected in series with the lamp, is applied to the circuit to prevent overheating caused by excessive current draw. Therefore, the function of ballast resistor is to regulates the current and reduces the voltage. However, for the lamp to light up, an arc has to be formed between its two electrodes. navy outdoor furniture cushions

WebOnce the starter motor starts the car engine, the ignition ballast resistor assists in reducing the voltage & current of the coil. Thus, low current can cause a low rise in temperature and it results in longevity of the ignition coil. However, the ignition system requires maximum voltage which is equivalent to the power source voltage. Web29 apr. 2024 · An ignition ballast resistor is often installed between the primary source of the ignition coil and the coil stud. It lowers the ignition coil's failure risk. When the starter motor turns on the engine, the ignition ballast resistor assists in lowering the coil voltage and current. As a result, a low current causes a low-temperature rise. Web15 apr. 2024 · When the engine is running the battery is at full 12v which will eventually fry a 9 volt coil, so a ballast resister is used to drop the voltage back to 9v. Voltage generally does not affect the points [which is a simple switching device] In fact 6 volt to 12 volt conversions can use the same points. navy outdoor loveseat cushion
