That sux about your battery! Hope no one was hurt.
The only recall for a potentially catastrophic failure that I remember was for the ignition switch in the steering column. It would short, or something, after you had turned off the ignition. On a rare occasion, you'd come back to your truck (and several other Ford vehicles, for that matter) and find it on fire.
There wasn't anything metallic that bridged the postive and negtive terminals of the battery? Any damage to the truck from the battery grenading?
