to carry the electricity from the coil pack to the spark plugs
To change the high-tension (HT) leads on a 1997 Peugeot 406 16V, first ensure the engine is off and cool. Disconnect the negative battery terminal, then carefully remove each HT lead from the spark plugs and ignition coil, taking note of their order. Replace the old leads with new ones, ensuring they are firmly connected to the spark plugs and ignition coil. Finally, reconnect the battery and start the engine to verify the installation.
It actually depends on the engine. But if it has HT LEADS (High Tension) Follow these from the distributor or electronic ignition unit and there are the plugs in the manifold of the engine
Good. They are not supposed to.
Yes, you should consider changing the high-tension (HT) leads if you notice symptoms like misfiring, rough idling, or decreased engine performance. Worn or damaged leads can lead to poor ignition and overall engine efficiency. Regular inspection and replacement as part of routine maintenance can help ensure optimal engine performance. If in doubt, it's best to consult a mechanic.
lambo sensor - cat issues - over fueling - ht leads break in the vacuum system
to test ht lead with out taking it out of coil pack. All you have to do is remove the 1 cylinder ht lead and pull the cylinder 5 ht lead out aswell and measure the resistance with multi meter. so now it will give you the reading. so its 1,5---2,6---3,4 ht leads.
4, you can always find this out for any car by having a look under the bonnet and counting the HT leads! *NB - HT leads are the leads from your coil pack which disappear into the engine, which provide power to the spark plugs.
They are attached to the end of the HT leads.
Engine won't start
Voltage transformer or potential Transformers are used in conjunction with Current transformers for metering and protection purpose in HT and LT power system.
For a 2002 Ford Fiesta, the ignition coil leads typically follow the firing order of 1-3-4-2. The cylinder numbering starts from the front of the engine, with cylinder 1 being the closest to the timing belt. The leads should be connected to the ignition coil in that order, ensuring proper engine operation. Always refer to the specific service manual for your vehicle for accurate information.
first check your battery if alright check your spark plugs check them for loose or damaged electroids and there colour then check your ht leads (plug leads) then the distributer cap and rotor arm for burn marks and excessive wear check the alternator and belt then the coil and ignition module
