Hooooleeee CRAP!! Look guys...I have NEVER seen this before. I replaced the selenoid,wired it to diagram,which was the way it was wired originally. Hooked up the positive and...yeah!!! no sparks or false starting. Problem solved,right? Not!! Heard a whining from the engine. I assumed that it was the alternator trying to catch the battery up and loading down. So,i went to turn the truck off and the engine quit. The battery began to spark at the terminals and both terminals began to smoke. i disengaged the positive and came in here to say...WHAT THE HECK IS GOING ON??????Help me,guys,help me.
