How to Repair an ATM Circuit

Fuses protect your car's electrical system.

An ATM circuit breaker, or fuse, is used for computer-controlled devices including cars. It is an automatic plug-in switch that protects an electrical circuit from damage caused by an overload or short circuit. The only way to deal with a broken ATM circuit is to replace it. These circuit breakers have small metal blades that plug into you vehicle's fuse box. You don't need great expertise to replace them.
