Thread: Goofy negative terminal lock on battery

I ended up having it towed to my local mechanic; I requested a new clamp and instead they remachined the bolt and reattached that stupid ass lock. Surprise, I was able to drive the car home but now it doesn't start. Yesterday it tried to not start so I disconnected and reconnected the battery and it started up after about 5 attempts at reconnecting, today I can't get it to start at all. I called the mechanic and they are saying it's a "different" problem; however, the car has never had this problem until I took it to them. Every time I turn the key the power goes out. I disconnect and reconnect the battery and the car has power again, but as soon as I try doing anything the power goes out again. I am wondering if there is a short at the battery now that is tripped the anti-theft system or something. Yesterday I was able to get the car to remote start and then put in the key and drive; today I am getting nothing out of it. The engine doesn't even try to turn; it's not like the battery is completely drained because I can reconnect it and get power to the inside of the car (lights, DIC). It's like something is shutting off the battery anytime I try to do something.
