Its about the efficiency of the coils. And i didn think they were inefficient, you're saying they are. Ive found out that its not really about the efficiency of the coil at all. Its the fact that the coil is being made to work differently to a typical transformer. Henn pretty well said most of it... A coil does NOT consume power, it transforms AC power. If you pass DC through the primary windings all you have is an electromagnet which sucks power & makes heat coz it essentially a short circuit. No current will be induced in the secondary windings. Its a change in a magnetic field that induces a current - DC fields do not change. The igniter creates a changing field by passing DC current through the coil for a set time (dwell time) to build up a field before the ECU opens the circuit. The field change is only a change back to zero, but its enough to produce a spark when the coil ratio steps the voltage up to thousands of volts. Its the dwell time that sucks the power, and if you dwell two coils in paralell off one igniter, you will double the current draw and blow the igniter. I stand corrected/educated. However, the resistance of a coil is nearly zero ohms, so if you wired two in series, you will have next to no effect on the operating amps of the igniter circuit when it dwells. Can anyone see a reason why this wouldd not work? [Report message to a moderator]
