Ignition Coil Power Source
WARNING: This page is about a different car, the 1996 Pontiac Firefly and 1996 Geo Metro. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition on. Using a voltmeter, measure voltage between positive terminal of ignition coil (Black/White wire) and ground. If battery voltage does not exist, check for open circuit in Black/White wire between ignition coil and 15-amp ignition (IG) fuse in fuse block. Fuse block is located behind left side of dash.
