How does the ignition coil work in a VW?

How does the ignition coil work in a VW?

In older cars, there is one ignition coils that sends the spark to a distributer, which then sends the spark to the waiting spark plug. Newer Volkswagen cars, however, there is one ignition coil for every spark plug which opens up the possibility of more coil failure Symptoms of a Faulty Ignition Coil

Can a spark plug break an ignition coil?

The ignition coil connector is another area that can cause all sorts of problems. Anytime you go to service a coil or spark plug you need to deal with the connector which is known for easy-to-break tabs, easy-to-miss connections, and easy-to-rupture seals.

Why is there no spark on my 68 VW?

Had a very similar problem on a 68 VW. No spark. Replaced the coil, center wire, points and the rotor. Nada. Turned out to be the center pin conductor in the rotor cap. Looked OK, but on close inspection, the little metal tip was gone. New cap cured the problem.

Can a VW air cooler get knocked out?

The VW air-cools must use a VW specific coil with an internal ballast or the ignition points will burn up and the condenser may get knocked out. If you do not have power at the coil with the key in both positions it’s quite possible the electrical part of the ignition switch is faulty.

Are there ignition coils that need to be replaced?

Although to their credit, the CSC was later revised to replace all ignition coil packs regardless of their performance. Even the replaced ignition coils were having problems, and faced with the scary consequences and limited supply of replacement parts the government wa petitioned to investigate the issue by VW owner Ron Strickland.

What happens if an ignition coil fails while driving?

And then there’s the whole misfire while driving scenario that can cut power to the engine, power steering, and power brake assist all at the same time. If an ignition coil fails it should trigger the check engine light and will likely result in error codes PO300, PO302 and PO304 depending on what cylinder is misfiring.

What kind of immobilizer does a VW TDI have?

Immo 3 also tells the ECU to do a calculation. Because of this, you can swap ECU on immo2 cars but not immo3 or above. The three main types of VW TDI immobilizer are immo2, immo3, and immo4. VW up to 1999 don’t have an immobilizer because immo generation 1 was not equipped on Volkswagen sold in North America.

What to do if your spark plug is not working?

If a good spark is present, the problem is probably not in the ignition system. Check the fuel system and/or stark timing. Weak sparks are orange or red and may be hard to see in daylight. If you did not see a spark, remove the coil wire from the distributor cap.

What causes spark plug wire to get cut?

Wire insulation that’s damaged by head can allow voltage to jump to the ground rather than jumping the gap at the bottom of the spark plug. Abrasion damage – When spark plug wires rub against engine parts, particularly sharp edges, it causes cuts and breaks in the insulation.

When to replace the spark plug wire in your car?

Be sure to first check spark plug wires for visual damage. Look for any signs of melting or cracking. The following situations call for immediate replacement of spark plug wires: Vibration damage – Constant wear and tear caused by engine vibration can loosen the electrical connection at the spark plug.

Where to get 12V for new HEI distributor?

The below diagram shows a 20gauge ignition wire goes to the + post of the coil (which the HEI does away with) then to the “R” terminal on the starter solenoid. Isn’t a 20gauge wire too small for 12v? I can not put a meter on the wire for I have finished the new wiring harnesses?

How many volts go through an ignition coil?

Place the red or black lead from the meter to the center of the coil (secondary post), and to either one of the terminals, 1 or 15 on the coil. A reading of 9,500 – 10,000 Ohms, sometimes less, indicates a good coil. A reading of 11,000 Ohms or more, or a reading of zero indicates a bad coil. How many volts go through a 1972 Beetle coil?

What to do if your ignition coil is not working?

Older ignition systems used breaker points to interrupt the circuit, while more modern systems “sense” the need for spark by means of a hall-effect switch or crankshaft position sensor. The ignition module uses the information to time spark generation. Test these components if the energized coil fails to function.
