Measure the Resistance of just the solenoid coil, and divide into 12 (for nominal voltage while pulling in the solenoid). Ignition coils play a vital role in the ignition system, delivering high-voltage electricity to spark plugs and initiating the combustion process. the wiring goes like so from the ECU -> igniter box -> coil packs Main EFI Relay -> Coil Packs So I am assuming the Relay -> Coil Packs is the majority of the power ECU -> Igniter -> Coil Packs (is a trigger so low Amp?) Sep 26, 2024 · Understanding the amperage draw of an ignition coil is crucial for maintaining optimal engine performance. When the voltage is removed from the coil, the energy has to go somewhere. These coils are capable of generating very high energy, but for the most demanding applications (say >200HP/Cyl), there are many other related factors that need to be well planned to make sure this high energy does actually make it to the spark plug gap reliably, and with minimal side effects.
