What happens if you use a too low resistance coil?
If you use an electronic type coil with points you will overheat it and burn the points. If you use a too low resistance coil for your electronic system, you will overstress it and possibly release its smoke. Does that help? raillard likes this. Yesterday I finally upgraded my 30 year old coil with a red coil from Vicks.
What to do if your coil pack is out of range?
If your readings are out of range, replace the coil or coils as necessary. Consult your vehicle’s service manual to obtain primary and secondary resistance specifications and identify primary and secondary terminals on the coil pack used on your car.
What makes up the bigger ignition coil pack?
As we said, the ignition coils make up the bigger coil pack. An ignition coil is an induction coil in a car’s ignition system. An induction coil is a spark coil that produces a high voltage from a low voltage supply.
What should the voltage be on a coil pack?
Turn on your meter and touch the spark plug wire terminals on one of the coils with the meter leads. You may get a reading between 5000 to 15000 ohms, depending on your particular model.

What should the resistance be on the ignition coil?
In checking the resistance on the secondary windings of the Ignition Coil (spark plug caps removed) my meter registered 20.5k oms but the manual suggests the reading should be between 8.4 ~ 15.6k oms. Does this higher that expected reading indicate that the coil is malfunctioning ???
Is it possible to run four coilpacks at once?
There has been quite a lot of discussion on running coils off the original 20V ECU. This concept works by using the original single ECU ignition output to fire all four fitted coilpacks at once. In theory this is not possible as one of the coils will always fire during the induction cycle.
How are smart coils and Dumb coils alike?
In terms of dwell control (spark firing time) these coils are combine elements of both self controlled / “smart coils” and externally controlled / “dumb coils”. They like the “dumb coils” will fire for as long as the duration of the activation of IGT signal from the ECU.
