How to Replace a Fuse in the Viper Car Alarmby Marissa Robert
Viper car alarms are hardwired into the electrical system of the vehicle. The electrical harness is color-coded to wire into specific parts of the electrical system. The way the harness is designed makes it simple to find the parts of the system you need. Removing the fuse in a Viper alarm is a standard part of installation, and replacing it is a simple task that almost anyone can do.
Pop the hood of the car and locate the red wire on the primary wiring harness, also known as the H1/2 wire. Find the positive terminal on your car's battery and follow the small red wire until you locate the fuse holder box on the wiring harness. Be sure to follow the small red wire. The large red wire connects the car's battery to the car. If neither of these fuses are blown, examine the fuses in the car's fusebox.
Open the fuse holder on the wiring harness and pull the fuse with the fuse removal tool.
Take the fuse to the auto parts store and find a replacement of the same type with equivalent voltage.
Pop the new fuse into the fuse box.
- For the parts of the wiring harness that connect to the wiring with connections in the car's fuse box, you can just replace the fuses that blow in the box, and you do not have to go looking for a special one on one of the wiring harnesses for the alarm. Consult the manufacturer's installation instructions for your alarm to figure out which systems the alarm ties into.
- Never replace a blown fuse with a fuse allowing a higher voltage.
- Always replace a fuse in the alarm system with the same type and voltage. Different circuits in the alarm can allow different maximum voltages. The type and voltage of the fuse you buy depends on which fuse you are replacing. Some of them are glass tube fuses, and others are blade fuses.
