How does a distributor less ignition coil work?
Distributor-less systems have no distributor cap or distributor rotor. The Secondary circuit transfers the spark to the spark plugs. Intermittent ignition coil failures are tough to diagnose because the windings are heat sensitive.
How can I tell if my ignition coil is defective?
Measuring a coil’s resistances can indicate whether it is defective or not. Another test is to see how well the spark jumps through the air, but there will only be a spark if there is 10v or more charged on the battery. Also, the air gap must be constant.

Where does the ignition coil go in a wasted spark system?
In the wasted spark system, a single contact is used for two leads, but each lead connects one cylinder. In General motors where high energy ignition (HEI) system used, there is no central post in the distributor cap. The ignition coil is placed on the top of the distributor.
What is the function of a Honda distributor?
The function of the distributor is to route high voltage form the ignition coil to the cylinders in the correct firing order. The distributor unit is made of a metal bowl, and the bowl contains a central shaft that is driven by the camshaft.
