1998 Chevrolet Express 1 Ton Van V8-5.7L VIN RSECTION Fuses
Sample Fuses:
The most common method of automotive wiring circuit protection is the fuse. Whenever there is an excessive amount of current flowing through a circuit the fusible element will melt and create an open or incomplete circuit. Fuses are a "one time" protection device and must be replaced each time the circuit is overloaded.
Fuse Rating And Color:
Auto Fuses, Mini Fuses and Maxi Fuses are color coded. The standardized color identification and ratings are shown.
For service replacement, non-color coded fuses of the same respective current rating can be used. The current rating of each fuse is molded into its head.
To determine whether or not a fuse is blown, remove the suspect fuse and examine the element in the fuse for a break. If the element is broken, replace the fuse with one of equal current rating.
There are, however, additional specific circuits with in-line fuses. In-line fuses are located within the individual wiring harness.
