Alfa Romeo Ignition Wire Set

How to Test Your Alfa Romeo Ignition Wire Set for Problems

Just like the veins in the human body, your Alfa Romeo ignition wire set serves as a significant link in an automobile electrical system. The wires transport electricity from the battery down to the spark plugs, enabling your vehicle to operate smoothly on the road. When the ignition wires fail, engine performance will decrease. On some occasions, your vehicle may not run at all. Below are some common issues related to ignition wire failure and the things that you can do to prevent the problem from getting out of hand:

Rough engine idling

Bad ignition wires can inhibit the transmission of electrical current from the engine down to the spark plugs. When this happens, you might notice some changes in your car engine's performance such as rough idling. An interruption in the flow of electricity could be due to some damages on the ignition wire insulation. A visual inspection is one way of checking for ignition wire breaks. Simply trace the length of the wires-bending them gently as you go-to check if there is any crack along the insulation. Replace the ignition wire if you find any damage on it.

Snapping noise

While your car's engine is engaged, you might notice a clicking noise from under the hood of your car. The noise or electrical snap is brought by a break in the ignition wires. To check for ignition wire breaks, turn off the engine, take a screwdriver, and run it along the entire length of the ignition wires. If there's a break on one of the wires, you'll hear a snap when you run the screwdriver along the wires. Replace the affected wires and turn on the engine once again to check for snapping noises.

Other troubleshooting tips

If you notice that your car's performance has decreased significantly, it could be because of the intermittent flow of electricity traveling from the battery to the spark plugs. When a visual inspection is not enough to diagnose the problem, use a voltmeter to measure the power running through the wires. Make sure to set the reading to OHM. Take note that normal reading depends on the length of the ignition wires you have in your vehicle. Replace any wire that reads below normal.

  • How to Keep Your Alfa Romeo Ignition Wire Set in Good Condition

    Routine maintenance is the key to having top-performing automobile, regardless of the type of vehicle you drive. Your Alfa Romeo ignition set requires as much attention as other car parts do- you need to preserve the good condition of the set to prevent erratic vehicle performance. When the ignition wires on your car wear out, your vehicle will suffer from poor gas mileage and other car part breakdown. Give your ignition wire set the proper attention it deserves with the following tips:

    Do a regular visual inspection of wires and wire ends.

    Your car's ignition wire set goes through extreme pressure, thanks to the high temperature under the hood. Because of this, the wires easily become damaged, and they fail eventually. A simple visual inspection of the wire and wire ends will help you identify problem spots before they go out of hand. The wires, which are made from delicate carbon fibers, wear out easily. Check the insulating materials for cracks, heat marks, and corrosion-if you notice any of these signs of damage, replace the wires immediately.

    Test the voltage of the ignition wires.

    If you see no signs of defects during a visual inspection, testing the ignition wire with a multimeter may give you information that is more accurate. The multimeter should show how much current goes through the wires. If there's plenty of resistance to the current, the wires will have to be replaced.

    Make sure that the ignition wires are connected properly.

    Ill-fitted ignition wires reduce fuel economy and engine performance. Your engine could misfire or the wires could short out. In order for the electrical power to flow smoothly through the wires, make sure that they are fitted correctly.

    Replace the wires before they wear out.

    Most vehicle owners wait until their car's ignition wires are completely damaged before replacing them. While that seems more economical, you are actually losing more money due to poor gas mileage and other car part repair or replacement. The ignition wires in your car may have some damage to them that you are unaware of, causing unnecessary wear to your other car components. It's best to change your ignition wires the same that you do spark plug changes, which is usually between 60,000 and 100,000 miles.
