Do I need resistor spark plugs?
Since resistor type plugs actually “resist” some of the spark energy, non-resistor type plugs actually deliver a more powerful spark. It is for this reason that most racing plugs are non-resistor types. However, in most automotive applications, a resistor plug is required for proper vehicle operation.
What is the purpose of a resistor plug cap?
Plug covers are manufactured to suit many applications and many are of the resistor type which provide electrical noise suppression across all frequencies whilst engine performance is not adversely affected.
What happens when you add a resistor to a spark plug?
Adding a carefully-chosen resistor to the ignition system’s secondary winding dampens the spark’s electrical noise, with little effect on plug voltage, since there is a surplusof unused voltage at the coil anyway. This damping is much like the muting of a tone on a guitar string with your finger on the string at the fret.
What should the ballast resistor be for electronic ignition?
The other important component of the electronic ignition system is the ballast resistor. It should be checked with an ohm meter and should have 1.2 ohms of resistance. Typically, a failure of the ballast resistor will result in the engine starting, but then dying as soon as the key is released from the start position.
What do you need to know about electronic ignition?
Chrysler Electronic Ignition The other important component of the electronic ignition system is the ballast resistor. It should be checked with an ohm meter and should have 1.2 ohms of resistance. Typically, a failure of the ballast resistor will result in the engine starting, but then dying as soon as the key is released from the start position.
What was the use of resistor plugs before radio?
Resistance in spark path was used before radio was common, before RFI was an issue. Most motors are inherently RF noisy regardless of resistance in spark path. Its shealding and grounding that prevent electrical systems from picking up the noise. Acception to the above is old carbed diesels. They use old checkers around radio telescopes.

Do you need a resistor on an ignition coil?
Quite simply, if your distributor has breaker points the answer is yes; if not, the answer is no. Click to see full answer. Moreover, does an ignition coil need a resistor?
