What happens if a car battery is put in backwards?
When a car battery is connected backward, a fuse designed to protect vehicle electronics should blow. If your vehicle doesn’t have a fuse (almost all cars do) designed for this purpose, you will send electrical current backward through systems in your car, including ECU, transmission control unit, and more.
What should I do if my battery fuse has blown?
Each fuse will have a number printed on top of it. Locate the one that is associated to the battery and you will have successfully located the main battery fuse to your car. Change the main battery fuse if it has blown to get your car back on the road again. Enter your comment here…
What happens when a main fuse is blown?
But a main blown fuse will keep you from using your car as it shuts off all of the electrical to the car. The fuse is there to keep a major short in the system from melting your wiring harness. If you have a blown main fuse, you have an electrical short somewhere in the system.
What happens when you hook up a car battery backwards?
When they put installed the battery, they hooked it up backwards and blew the main fuse. When the main fuse was replaced and I was driving off I noticed that the charging light was on, and the radio/clock was not working. Taking it back, they confirmed that the alternator was dead and replaced it (with me paying for it).
Where can I find the main battery fuse?
The best source to find the main battery fuse is in your owner’s manual. Look in the table of contents or index to properly locate the fuse box. Go over diagram.
