What is the purpose of a condenser on a distributor?

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 .

on February 11, 2022. We all know that a car won't run without a condenser . Neither does the initial arc cause any malfunction of the points, so there is no reason for them to fail automatically.

How to Test a Condenser in a Small Engine

A condenser can fail for one of a few reasons. Pipes and seals may have deteriorated, allowing refrigerant to leak out and air to get in . The air that gets in can cause ice crystals to form, which block and damage the condenser. Metal flakes from a faulty compressor can have the same effect.

Will a car run without an ignition condenser?

We all know that a car won't run without a condenser . Neither does the initial arc cause any malfunction of the points, so there is no reason for them to fail automatically.

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.Jan 11, 2016

Electronic ignition does away with the need for a traditional condenser and points , so these need to be removed by unscrewing them from the distributor base-plate.

A blocked condenser can cause a process called short-cycling , when your system cycles on and off rapidly, not allowing for the proper function of your AC system. This will eventually cause more wear and tear than your system should have to withstand, which means you can find yourself facing a premature breakdown.

How do you test a bad distributor condenser?

If your vehicle runs rough, the engine will not fire, or the vehicle will not start at all, the points and condenser system may be failing .Jan 11, 2016

Voltage drop across it and some value of current shunted to ground thru it. Exceed its temperature rating . All of these things can lead to failure of the capactor dielectric and turn the cap into a shorted one. No capacitor-no spark!Apr 6, 2005

Weak spark is often the result of a bad condenser (and it's a cheap part to replace). If you see higher resistance here, then you need to clean and check the connections and the circuit path to ground through the points. Also check resistance between the distributor body and the engine block.

What happens when ignition condenser fails?

If the condenser has been failing for a while, the contact points could be damaged from excessive sparking and it can become more difficult to get the car started and it won't run as smoothly . It may run smoother when the engine timing is advanced but will stutter when the timing is slowed down.

We all know that a car won't run without a condenser . Neither does the initial arc cause any malfunction of the points, so there is no reason for them to fail automatically.
