Q&A: Fitting new high tension leads in cars
How do high-tension leads or ‘ht leads’ play a critical role in the ignition system?
High-tension leads, also known as HT leads, play a critical role in igniting the fuel mixture in the combustion chamber by transmitting a higher voltage from the distributor to the spark plugs. These ignition cables ensure that the spark at the plug is strong enough to ignite the air mixture in the cylinder head. Properly functioning HT leads are essential for smooth engine operation, preventing misfires and loss of power.
What types of HT leads are available, and how do they differ?
There are several types of HT leads, including copper core leads, silicone HT leads, and resistor leads. Copper core conductor leads offer high conductivity but can cause radio interference. Resistor-type leads reduce electromagnetic interference but have a slightly higher resistance. Silicone HT leads are popular due to their thick insulation layer, which protects against heat and moisture. The type of engine and ignition system determines which type of HT leads are most suitable.
Why is it important to replace the HT leads periodically?
Over time, HT leads degrade due to heat, moisture, and wear on the conductor and shielding. A worn ignition lead can cause a weak spark, resulting in poor combustion, loss of power, and engine misfires. When replacing the HT leads, it is important to use leads made from rubber, plastic, or Teflon with a thick insulation layer to prevent voltage leakage. Ensuring the appropriate length and correct spark plug connectors improves ignition efficiency.
How can a multimeter be used to test the condition of spark plug leads?
A multimeter can measure the resistance of spark plug leads to determine if they are still functioning properly. To test the HT leads, set the multimeter to ohms and connect the probes to both ends of the cable. A higher than expected resistance indicates internal damage or degradation. Copper core HT leads typically have very low resistance, while resistor leads will have a specified range. If the resistance is too high, replacing the HT leads is necessary to maintain proper engine spark.
How does the distributor cap affect the performance of plug wires in an ignition system?
The distributor cap plays a crucial role in directing high-voltage electricity to the correct spark plug wires. If the cap is worn or cracked, it can cause misfires and weak ignition. When fitting HT leads, ensuring a clean and secure connection between the distributor cap and plug wires makes a big difference in achieving a strong spark. Using high-quality HT leads made to measure for the ignition system helps maintain consistent performance.
What should be considered when selecting bespoke HT leads for an engine?
Bespoke HT leads are often referred to as a performance upgrade because they are designed to match the specific requirements of an engine. When choosing leads, factors such as conductor type, insulation material like EDPM or silicone, and correct plug cap size must be considered. For classic and industrial engines, using copper core of the cable can improve conductivity, while resistor leads help reduce interference. Ensuring the right fit and length for the ignition system improves reliability.
Why is it a good idea to use 8mm leads instead of standard plug wires?
Using 8mm leads provides better insulation and durability compared to standard plug wires. The thicker insulation layer also reduces the risk of voltage leakage, which is essential for high-performance ignition systems. These leads are especially useful when paired with a Lucas Sports Coil or other high-voltage ignition components. Choosing the correct HT leads can make a big difference in ensuring a consistent spark and smooth engine operation.
How does the technique used in fitting HT leads affect their lifespan?
Proper fitting of HT leads ensures long-term reliability by preventing excess wear at connection points. When installing leads, using a rubber boot to secure connections and applying dielectric grease to plug caps reduces corrosion. If the thread is stripped on a spark plug terminal, it can cause a weak connection and misfires. Ensuring that connections are made securely and that drop leads are routed away from excessive heat improves the durability of the ignition system.
