What type fuse to use in a 86 Buick grand national?

The type of fuse to use in an 86 Buick Grand National will vary depending on the specific electrical circuit that you are working with. However, generally speaking, the Grand National uses mini fuses throughout its electrical system. These fuses are typically rated for either 5, 10, 15, 20, 25, or 30 amps. The specific amperage rating of the fuse required for a particular circuit will be indicated in the vehicle's owner's manual or on the fuse panel cover. It is important to use the correct amperage fuse for each circuit, as using a too-low-amp fuse can cause the fuse to blow prematurely, while using a too-high-amp fuse can potentially cause damage to the electrical components on the circuit.
