A Coil On Plug ignition system has a coil for each spark plug ( the 5.4 L has always been Coil On Plug - C.O.P. ) the newer 4.6 L are now Coil On Plug instead of having 2 coil packs - each coil pack handling 4 engine cylinders / spark plugs and using spark plug wires
Coil 4
The coil to the spark plug is called an ignition coil on a Yamaha EF600. It is also referred to as the spark coil. These two terms are used for any coil to the spark plug in a vehicle.
No. The coil provides the spark and the module tells the coil when to spark.
The purpose of a coil pack is to supply the spark to the spark plugs.

Unplug the connector on the base of the coil. Remove the bolt that holds the coil in place. Pull the coil and spark plug boot off the spark plug. Install new coil in reverse order.
You apply 12 volts to the coil primary and then release it . The electricity will go through the secondary coil and spark the spark pug.
Could be that side of the coil is burned out.
There are no spark plug wires. Each spark plug has its own coil and the spark plug attaches to the coil directly. To access the coil and plug, you need to remove the black plate on the top center of the engine (4-6 torx screws, I believe).
I'm not a mechanic / technician but I am wondering if cylinders 1 and 4 come off of the same coil in the coil pack . As far as I know the coil pack has (2 coils inside ) with 4 towers for the spark plug wires
