Originally Answered: What happens if a ground wire is not connected? … If there is enough current flow from the device’s damaged wiring, through the ground wire, it will cause either a fuse or circuit breaker to cut off power to the device, preventing further shock hazard.
Do I connect negative or positive first?
Always while connecting, positive terminal first then negative and the ground (to avoid fuse). While disconnecting negative terminal comes first.
Why do you remove the negative terminal first?
Because the negative end of the battery is connected to ground. It is only a slight advantage to disconnecting the positive terminal. The reason for this is because while connected, any part of the chassis will complete the circuit and the chassis is one big wire that is easy to bump into.
