Regarding this, why do we need to disconnect the spark plug wire from the spark plug?
A: Probably the most important safety precaution that you can take when doing your own repairs or maintenance on a lawnmower is to disconnect the spark plug wire before you do anything else. ... This is especially true when doing anything with the mower blade.
Likewise, people ask, can you break a spark plug wire? Grab firmly onto the spark plug wire boot, then twist in either direction and pull off simultaneously. This ensures the wire will break free is slightly corroded. ... To reinstall the spark plug wire, just simple push firmly back into place until you either feel or hear a clip.
Can you change spark plugs without changing the wires?
It is not necessary to change the wires but it's a good idea. Here's the reason. If your spark plugs have been in the engine too long the component at the end of the plug get's oxidized over time from having such high voltage run across it to jump a gap and create a spark.
Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion.
Common signs of failing spark plug wires include a decrease in power, acceleration, and fuel efficiency. In addition, the engine light coming on or visible damange to the cables can be signs of a failing wire.
Remember to leave additional length in the wires to enable the distributor to freedom of movement. ... By reducing the resistance in the plug wires, the coil does not have to work as hard because less voltage is lost to the resistance between the coil and spark plug.
The ignition cables on a car are made to last about 60,000 miles before they have to be replaced. In some cases, the wires will need to be replaced due to the rubber boots on the end getting damaged and now allowing for a good connection with the spark plugs.Share to:FacebookTwitterPinterestEmail
