What happens when you disconnect a negative battery terminal?
The electrical power in a car’s engine is activated by the battery. Contact between the negative battery terminal and the battery, even if the cable is not clamped onto the battery, may reactivate the electrical system within the car. This would negate all the reasons you have done this much work to ensure the cable is disconnected.
Is it bad to remove cable from negative trickle charger?
So that is the downside to removing the cables from the battery to charge it. That and the risk of spark increases. Also, if you remove the cables, you have to connect the charger’s ground clamp directly to the negative terminal on the battery instead of the frame or block.
Can a negative terminal be connected to a positive terminal?
Subsequent shorting of the positive terminal to ground will then produce no current flow because the current has no return path to the negative post. And, of course, always reconnect the ground last.

Why does Chevy say to remove the negative battery terminal first?

Q: A friend of mine told me that I should always disconnect the positive terminal of the battery first to keep the electricity from spilling out of the battery. I can’t see how this would matter.

Like I mentioned above, simply disconnecting the negative cable is not enough to stop your battery from losing charge. Don’t get me wrong, it is definitely better than nothing and it will go a long way in preserving your battery’s charge while you’re away. There’s something that every battery undergoes and that is called self-discharge.
Why is there no current on the negative terminal?
If you remove the negative clamp and inadvertently complete a circuit to ground, there will be no current flow because the ground clamp is already grounded. Subsequent shorting of the positive terminal to ground will then produce no current flow because the current has no return path to the negative post.
