Ignition Coil Power Source
WARNING: This page is about a different car, the 1997 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition on. Using voltmeter, check for 12 volts between ignition coil positive (+) terminal and ground. If voltage is not present, check battery feed, main fuse, ignition switch and fusible links. See appropriate wiring diagram in WIRING DIAGRAMS article.
