95 Taurus and the battery was dead. I got a new battery and started to put it in. First thing I should have noticed as wrong was sparking at the negative terminal when I connected it. Before I even tightened the termnal, smoke, then flames in the wiring up by the firewall, between the shock tower (passenger side) and fire wall.
Very exciting! After oh shhhht I jerked off the negative cable and the flames were gone. A wire in the harness was burned completely through.
Anybody have any insights on the cause of this dead short? Key was not in the ignition, just replacing a dead battery. Thanks.
