What does a condenser do in an electronic ignition system?

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.

Do you need a condenser with electronic ignition?

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.

What causes ignition condenser failure?

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.

Where is the condenser placed in the ignition circuit?

The condenser may be fitted outside the distributor, or inside on the contact-breaker baseplate; on a few cars it is fitted into the wiring somewhere near the distributor.

Can a bad condenser cause no spark?

A failing points and condenser system can cause rough running, misfires, lean and rich conditions. … If your vehicle runs rough, the engine will not fire, or the vehicle will not start at all, it may the points and condenser system that is the issue.

Does a ignition condenser need to be grounded?

The condenser body needs to be grounded, and the lead wire can connect anywhere between the coil and points. … You can screw the condenser bracket to the coil mounting bracket, and connect the lead wire to the coil primary points wire connector.

Does a condenser go to positive or negative?

On a – negative ground system always connect this condenser to the HOT + Positive side of any electrical item. (On + positive ground systems connect to – Neg.

How do you diagnose a bad ignition condenser?

If you suspect the condenser is going bad, you can sometimes tell by watching the engine run while it is in idle. The point cover needs to be removed and some engines won’t run without it, but if the condenser is going bad, you are likely to see a large yellow spark jump between the two contact points.

What are the symptoms of a faulty condenser?

If your AC condenser is about to experience failure, you may notice one of the following warning signs:

  • Loud and abnormal noises coming from the unit.
  • Significantly reduced cooling capability from the unit.
  • The unit is leaking a noticeable amount of fluid past the typical amount of condensation.

How do you test an ignition condenser?

How to Test a Condenser in a Small Engine

  1. Remove the condenser from the engine. …
  2. Switch the volt ohmmeter to the ohms position. …
  3. Touch the red lead to the hot connector on the condenser. …
  4. Remove the leads and reverse the placement to the condenser. …
  5. Movement from the meter’s needle indicates the condenser is good.

What are the 3 types of ignition systems?

There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP).

What happens when a distributor condenser goes bad?

A failing points and condenser system can cause rough running, misfires, lean and rich conditions. … If your vehicle runs rough, the engine will not fire, or the vehicle will not start at all, it may the points and condenser system that is the issue.

How do you tell if you have points or electronic ignition?

If you do have a standard distributor cap, you can open the cap up and peek inside. A points type ignition will have what are called points (duh) installed in the distributor, just below the rotor (that colored plastic part that spins around when the engine is running).

Will an engine run without a condenser?

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.

What causes weak spark?

The ignition coil is what generates the spark, so if it’s present at the right times but weak, the coil is usually to blame. It is a voltage amplifier. If only a portion of the coil inside it shorts, it will partially amplify the voltage so the spark will be weak.
