Default What possible damage can wrong terminal connection of new battery cause to 2005 Toyota corolla 180i?

When to newly opened car battery fitment center to change my car battery. After purchasing the new batter, the dude fitted the new battery wrongly with the positive wire from the car connected to negative terminal of the battery. He even used hammer to force the positive clip into the negative terminal of the battery.

As a result the car horn/hooter sounded for a while and stopped. Afterward, there was no light in the ignition.

What possible damages could this error cause to the car?

It can burn out the diodes in the alternator, and it will not charge. plenty of chances to mess up electronics. They are responsible and should fix anything that goes wrong.

There is a fuse box under the hood that should have a fuse for the battery and one for the alternator, both unconventional styles and more than 50 amps each. You can count on the battery fuse being blown and the alternator fuse may be blown as well. Beyond an occasional conventional fuse being blown it is rare to have more dmage than that.

You would think the hammer would have made him wonder.
