Quick Answer: How Do You Troubleshoot Points And Condenser?

How do you test a point condenser?

How to Test a Condenser in a Small EngineRemove the condenser from the engine.

Switch the volt ohmmeter to the ohms position.

Touch the red lead to the hot connector on the condenser.

Remove the leads and reverse the placement to the condenser.

Movement from the meter’s needle indicates the condenser is good..

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.

What does a condenser do in 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. Arcing is caused by the effect of self induction in the coil as the points interrupt the flow of current.

How does a points and condenser system work?

Conventional Ignition System. … Instantaneously, when the points open (separate) current flow stops through the primary windings of the ignition coil. This causes the magnetic field to collapse around the coil. The condenser absorbs the energy and prevents arcing between the points each time they open.

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.

Why do ignition points fail?

The high voltage now travels over to the distributor, where the rotor metes the high-voltage pulses out to the correct spark plug. 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.

What is the function of the condenser?

The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser. The major types of condensers used are (1) water-cooled, (2) air-cooled, and (3) evaporative.

How do you convert points and condenser to electronic ignition?

A conversion to electronic ignition can be as simple as removing the old points and installing a new magnetic pickup in the distributor.Your Electronic Ignition Conversion/Upgrade Kit.Most Electronic Ignition System Conversions Begin with Changing the Distributor.Installing a Factory Replacement Ignition Control Module.More items…•

Does dwell affect timing?

The dwell, as well as spark plug gap, do have an effect on ignition timing. The later the points open, the later the spark comes and retards the timing. The earlier the points open the sooner the spark comes and advances the timing. That is why timing is the last thing to be set in a tune-up.

How do you replace points and condenser?

Part 1 of 1: Replacing a points & condenserMaterials Needed.Step 1: Disconnect battery. … Step 2: Locate and remove distributor cap. … Step 3: Disconnect and remove the set of points. … Step 4: Remove condenser. … Step 5: Install new condenser. … Step 6: Install new points set. … Step 7: Grease distributor.More items…•

Can a bad condenser cause weak spark?

If you do have this good ground connection through the points, then you may have a bad condenser. 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.

What can cause weak spark?

The following issues can present in different ways or operating states, but the most prevalent are listed below.Cracked spark plug porcelain. This causes misfiring or bucking under load. … Fouled spark plug. … Weak ignition wire insulation. … Weak ignition coil.

How do you test a condenser with a multimeter?

How to measure capacitanceUse your digital multimeter (DMM) to ensure all power to the circuit is OFF. … Visually inspect the capacitor. … Turn the dial to the Capacitance Measurement mode. … For a correct measurement, the capacitor will need to be removed from the circuit. … Connect the test leads to the capacitor terminals.More items…

How do you test a chainsaw condenser?

Touch the red lead to the hot connector on the condenser. Place the black lead to the metal case on the condenser. The meter’s needle should jump slightly to the right (toward 0-ohms), then should drop back to the left towards infinite resistance). Hold the leads in place for 15 to 20 seconds.

How can you tell if a point condenser is bad?

Symptoms of Bad or Failing Points & CondenserVehicle not starting. If your vehicle will not start, it is possible there is a problem somewhere within the points and condenser. … Engine will not fire. When you try starting your vehicle, if the engine turns over but does not catch, this is a potential points and condenser problem. … Engine runs rough.

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.

What happens if point gap is too small?

When the points open, the light will come on. … Also, having too small of a point gap increases point “dwell” and can cause the points and coils to overheat. Too wide of a point gap can lead to a weak spark. The procedure, in a nutshell, is you set point gaps between 0.014″ and 0.16″.
