Even at 59 years old I guess I don't know everything! This is a new one on me. A friend with a chevy powered T-bucket had a starting problem today. He told me that the car was running and he shut it down briefly. He said that when he re-started that everything was dead, like with a dead short. He said the battery started to boil. After trying a few common checks he hooked a battery charger to it and heard a loud CLICK. The car started and all systems worked fine. He said that the 12 volt system had reversed it's polarity. WHAT??? Have you guys heard of this? Am I just that dumb?
