Battery warning:
I knew you always connect the positive to positive and negative to negative of the battery but didn't know about the order. The wrong order could result in at least a mess or, at worst, dangerous. See the message below.
The reason why you disconnect the negative terminal first and reconnect it last is because when the negative cable is connected, all the steel in the vehicle becomes a ground. If you’re reconnecting the positive terminal and accidentally touch the inner fender or any other metal surface with the wrench, it will cause a short circuit and could result in – at best – a lot of sparks. At worst, it could cause an explosion if the battery is emitting hydrogen sulfide gas.
