there is only one coil of you are getting power to it but no spark replace it
pull each coil off with harness attached put on a plug and crank the car as someone holds the coil with plug still attached along with harness hold it to anything metal and check for spark
The pickup coil is part of the distributor in a car which times the firing of the spark plugs, it detects the magnetic field from permanent magnets spaced so that when the coil passes by the magnet, it sends a signal to the car, which indicates the appropriate time to fire a spark plug, so that they go off in the proper timing sequence.
general rule NO, but check with your state to be sure
The COIL HAS A POSITIVE AND A NEGATIVE TERMINAL. If you look at the top of the coil, it is generally marked + and - on the top.
There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.
check your answer
coil pack
I would check coil, leads, and plugs.
i'd check the coil pack or distributer depending on the age of your car
Check the BMW for ignition fire. Check the coil pack. Check the distributor or crank sensor depending on the year of the car.
well depending on the car if you look at the cylinder of the coil you suspect is bad you might see Browning almost like the cylinders overheating... Or pull the coil out and check for what looks like melting on the coil itself. also try pulling coil partway out of the cylinder and have someone turn car to accessory but not on! if you see a spark then the coil is working fine. hope this helps :)
i have a diagram for the car coil fence
There are a few steps: The easiest will be to try using the coil from another vehicle preferably one from a car with te same engine size ( DONT WORRY THE BORROWED COIL WONT DAMAGE). Also try changing out the wires between the coil & distributor. Lastly check the wires that should deliver power to the coil. Hope this helps ;-)
That depends; on an older car I'd suggest that it's probably the condenser, but if it has an electronic ignition I'd also check the ECM and coil.
Perhaps bad coil or coil pak?
Hi, I am no expert, but I have had to change several coil's in a 4.6 Ford. Get a code reader that plugs in under your dash, about $15.00 or so, or you can go to Auto Zone, they will read your code for free. This will tell you which coil is bad.
At what speed does it occur? Is it accompanied by shaking? Check ur plugs, wires, and Ignition coil packs
