Ignition condenser - Find your perfect used car today A condenser, or capacitor, can be tested using a condenser tester. The tester applies a high voltage to test for leakage and measures the storage capacity, or capacitance, of the part.
Retest the condenser several times for a consistent reading. In operation the condenser will "ring" at up to 300 volts, so the condenser needs to be rated much higher, no less than 600 volts DC. The ignition will likely work with any capacitance value between 0.05 and 0.6 microfarad.
Jun 30, 2012· Does anyone know what the capacatance value (in micro farads) of a condensor for a four cylinder 6 volt ignition system? This is for an eight cylinder engine that uses dual ignition; two seperate sets of points, coils and condensors. The originals are shorted out (background in …
Chapter 5 Capacitance and Dielectrics . In the limit where the plates are infinitely large, the system has planar symmetry and we can calculate the electric field everywhere using Gauss's law given in Eq. (4.2.5): . separation because the smaller the value of d, .
By John Cornforth (DA7C) The condenser (nowadays called a capacitor) is a vital part of the traditional points and coil ignition system used in later Austin 7s. When the contact points open, the capacitor allows the several amps of current flowing in the coil to drop to zero in a rapid but controlled manner.
Oct 15, 2017· Rustedwrench Well-Known Member. In modern transistor ignition systems, where the transistor replaces the points, a capacitor on coil (-) is not used. A modern IGBT transistor has only a few hundred pF of capacitance, a value much less than a points capacitor. The use of a large capacitor, charged by prior ignition event,.
Apr 05, 2016· The production tolerance of actual capacitance value varied somewhat. There was a routine to either shorten or lengthen the wiring (to change the capacitance slightly) and keep deposits from building. A good, quality condenser should last a long time and routine replacement not necessary for any reason I can think of.
Ignition capacitors are more common in older vehicles than modern ones, which are most often equipped with electronically-controlled ignition. With age, an ignition capacitor can lose its ability to hold a charge. A leaking capacitor can prevent an ignition system …
Feb 23, 2006· Hi Can anyone tell me the capacitance value of a condenser used in a car ignition circuit (across the ignition coil)? Thanks Naveed. Network Sites: All About Circuits . Can anyone tell me the capacitance value of a condenser used in a car ignition circuit (across the ignition coil)? Thanks Naveed. Click to expand. 0.22 microfarads comes to .
Apr 18, 2012· Anyway, I've yet to find an old Lucas condenser whose capacitance value has changed significantly, even though their leakage resistance is horrible, so it's unlikely you'll need a capacitance meter. If you search for 'megommeter' you will find Chinese-made units that test resistances with applied voltages of 250V or higher for ~$50 delivered.
Book Values; Rebates & Incentives . somewhere within the points and condenser. The ignition system can be a . appeared on YourMechanic as Symptoms of Bad or Failing Points & Condenser.
May 13, 2010· Also the same part is used for the alternator condenser and the gas tank sending unit condenser! Since HD used Chevrolet points I think they also used the Chevy condenser. The early VW also appears to be physically the same. A six volt coil is 1.5 ohms and a 12 volt coil is 3 ohms.
Start studying Prepware Ignition and Starting Systems. Learn vocabulary, terms, and more with flashcards, games, and other study tools. . In a high-tension ignition system, the current in the magneto secondary winding is. . Capacitance afterfiring in most …
Check the capacitance of the ignition capacitor. Touch the positive and negative leads from the capacitance meter to the respective connections of the ignition capacitor. The readout on the meter display should be close to the nominal value, typically within a 10 percent range. Remove the meter and test leads from the capacitor and turn off when done.
Jul 24, 2008· I would guess that the value of the condensor (capacitance value in Farads) is different between a 6 volt and a 12 volt system. It is a bit of a balancing act to get enough capacitance to prevent the arc from happening when the points open, versus too much capacitance that can cause an arc as the points close and the capacitor is discharged.
Feb 14, 2015· Re: Ignition condenser value question Interesting discussion. My JB manual say's the points condenser is a 0.3 ufd and its purpose is to prolong breaker point life by reducing the arc across them and it also aids primary field breakdown when the points open.
Apr 27, 2018· The HVAC motor start & run capacitors are doing a very different task than an ignition condenser. Those carry 10's of ampreres of current all day long and over 100 amperes during starting, whereas the ignition condenser carries about 4 amperes for milliseconds at each break.
An ignition condenser is a capacitor that is designed to hold a small amount of current inside the engine's ignition system. Its main purpose is to act as a ground for the electric charge to prevent the two electrodes from sparking with each other.
Phys E-1bThe Physics of the Automotive Ignition System Spring 2008 — 3 — Set up the PASCO function generator as in Figure 2 to give you an "on/off step" voltage (square wave output) and apply this to the primary of the coil with a 4 Ω resistor in series.
About Capacitors in Ignition Systems. I would like to offer my help to those folks that may not understand capacitors also called condensors. What it is; two metal plates placed near each other and separated by insulating material such as paper.
Apr 27, 2018· As to wrong value, I claim that not running due to wrong value is almost a big "never", because I have personally tried values from 0.01uF in increments, up to over 55uF(generator noise suppression cap) and still have a running engine, Typical ignition condenser value is about 0.2uF.
Jan 01, 2011· Automobile ignition systems used to use points and a capacitor, known as a "condenser" in wrenchhead-speak. We electronics types stopped using the word "condenser" back in the '60s. The inductance of the ignition coil primary winding and the capacitor form a tuned circuit. Does anyone know, offhand, what the value of the "condenser" is in uF?
Capacitor is a device that is used to store an electric charge. It is basically an arrangement of conductors. Condenser is an old term for capacitor. Therefore, there is no difference between a capacitor and condenser in electronics.
In short, the capacitor in an ignition system manages the rate of change of the voltage in the low tension ignition circuit when the contact breaker opens, to prevent the energy that is meant to produce an HT spark at the plug from being wasted as arcing at the contact breaker.
