As the engine rotates, the distributor shaft cam turns until the high point on the cam causes the breaker points to separate suddenly. … The condenser absorbs the energy and prevents arcing between the points each time they open. This condenser also aids in the rapid collapse of the magnetic field.
Basically the function of a condenser in a coil ignition circuit is to reduce the spark at the contact points as they open in the distributor and thus minimise burning and pitting of the points. Arcing is caused by the effect of self induction in the coil as the points interrupt the flow of current.
Yep, cars WILL RUN without a condenser (it’s really a capacitor) but the points will burn out faster! Electrical current will try to keep flowing when a switch (the points in this case) are opened so there will be an ‘arc’ across the points until they are open far enough to break the circuit.
Points. Ignition points are a set of electrical contacts that switch the coil on and off at the proper time. The points are opened and closed by the mechanical action of the distributor shaft lobes pushing on them. The points have a tough job, switching up to eight amps of current many times per second at highway speed …
The purpose of the Pulser coil is to give ignition signals to the engine and ignition system. The resistance categorizes pulser coils. They are pulse generators that work when the engine is ignited. … If the AC current generated is zero, then the coil is not working.
3. Engine runs rough. A failing points and condenser system can cause rough running, misfires, lean and rich conditions. If the engine is difficult to start, and runs rough once it does start, then it is time to contact a mechanic to have a look at the system and find out exactly what the problem is.
A condenser is part of the ignition system used on most small engines. The condenser is physically the same as a high voltage capacitor used in other types of electrical circuits. … If the condenser malfunctions, the small engine will not run. Various small engines have different locations for the condenser.
The Haynes manual recommends a point gap of . 016-. 020 inches for engines used in the P1800.
When the points are touching each other electricity runs from the battery, through the coil and to the engine block, which is grounded to the negative terminal on the battery. The current running through the windings in the ignition coil builds up a powerful electrical field that is unleashed when the points separate.
A bad condenser can cause a number of problems. For example, your AC may not be able to produce as much cool air as it should be able to, resulting in higher energy bills for you despite less efficiency and comfort. Keep in mind, this can also be a sign of a compress issue or a refrigerant leak.
If the spark is a big fat one, then the condenser is bad and needs to be replaced. 2. If no spark is visible, check to see if the points or wires are shorting to ground either at the points or at the primary terminal screw going through the housing.
In essence, the ignitor works to enhance electrical signals and produce a larger flow of electricity to the coil that helps your spark plug operate. In this way, it is an essential part on gas-powered golf carts but is usually not found on electrical carts as there is no need.
The pick up coil is an integral part of the vehicle ignition system. The pick up coil is designed to generate a voltage pulse that is used by the ignition module as an RPM and timing sensor.
This is an older style of ignition system that uses points, a distributor, and an external coil. … In an electronic system, you still have a distributor, but the points have been replaced with a pickup coil, and there’s an electronic ignition control module.
To test the points with a multi-meter simply unhook the wires to the points and put one lead on the post where the coil and condenser hooked up and the other to the block. With the meter set on “Ohms” at a low setting turn the engine over. When the points open there should be maximum, infinity, resistance.
As they close, current from the ignition switch flows through the contacts into the coil’s primary windings and then off to ground. … All that current flowing across the points doesn’t like to stop suddenly, and can initiate a small arc, which eventually erodes the tungsten contacts.
If your car has standard ignition system wiring and a ballast coil, current flow through the circuit will be excessive and the points, condenser, and coil all may fail prematurely.
Any condenser of the same value will work. They are indifferent to voltage but the capacitance (microfarads) should be the same or at least close. They aren’t that accurate from new. If the condenser is perfect your points won’t burn.
No such thing as a 6V or 12V ignition condenser. Irrespective of applied primary voltage (6V, 12V, 24V) the condensers are made to withstand the flyback or reverse EMF voltage made by the coil as it’s magnetic field collapses when the points open. That is ~80-100 volts for a typical iron core type ignition coil.
With a condenser coil that is dirty or blocked, the unit will have to work harder to achieve the same results. … A dirty condenser coil with have a reduced ability to transfer heat to the outside air and this can lead to a less effective cooling system.
One of the key factors that makes a spark plug work well, or not, is the size of the gap between the electrodes. … However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn’t run at all.
A wider gap will advance the timing. The sooner they open the wider the gap will be. As you increase the gap, the dwell angle will decrease because the points will open earlier. The spark occurs when the points open, hence increased spark timing.
Should points be open or closed at TDC? Theoretically, the points should be just in the process of going from closed to open at #1 TDC. … if you watch the points while you rotate the distributor body, you will see that you can make the points open OR close just be rotating the housing.
