What happens if you connect the battery the wrong way?
In pre-ECU cars, it was no big deal to connect the battery wrongly. The battery did not charge but typically everything else except the radio would work normally. Early ECU cars may not be so lucky but a vehicle made in the last few years may survive. The alternator may have suffered.
What happens when you connect a car battery backwards?
Nevertheless, there are some general issues that occur in most vehicles when its battery is connected backward. Even if you don’t realize what you have done, your car will not start because of the wrong connection in your battery.

What happens to the battery with reverse polarity wiring?
Connecting a Battery to Another Battery with Reverse Polarity If a battery in the first car is connected wrongly to the battery placed in another car to charge the second battery through the first one, it may explode and burn or permanently damage the battery (ies).
What happens if you connect the wrong battery cable?
Charging a battery can help extend the battery’s life and potentially save you money.

What happens when you hook up a battery backwards?
Usually when the battery is connected backwards, it will short out the charging system. I recommend connecting the battery up the way it should be and start it up. Once started use a meter to check the voltage at the battery. It should be above 12.5 volts dc. If the voltage is dropping, you will need to replace the charging stator.
