Automobiles are just like houses in the way they are wired, framed, sided, plumbed and have many working parts that keep things running smoothly. Wiring works basically the same way it does in the home. Fuses are still used and when they blow it is helpful to know which one to check or change.
If a person has an owners manual this is full of vital information that will help in this process. Owner’s manuals will have the fuse panel layout and what each of the fuses controls. The fuses are much like breakers in the way they will trip when overloaded. They can be checked by using an ohm meter.
Here is how to change a plug in or glass tube fuse easily and with certainty.
Tools needed: Plastic fuse tongs, ohm meter or ohm checker, a good set of eyes and a steady hand.
Step 1: First thing to do is find the fuse that is suspected of being blown. This can be done by first reading the owner’s manual or looking to see if there is a fuse chart on the cover of the box. Fuses will be labeled headlights, radio, air conditioner and so on. This gives one the general idea of where to start. One instance being if the headlight and tail lights are not working start by looking at the fuse marked the same.
Step 2: If the fuse is a glass tube use the plastic tongs and grasp it on each side and pull it straight out. The fuse may be a little hard to pull out but this is normal.
If the fuse is the snap in plastic coated kind then this one will pull out as well. Use the plastic tongs and grasp it and this one will pull out much easier.
Step 3: After the fuse is out then test it with an ohm meter or tester and if it is bad replace it with the same kind and amperage fuse. Do not replace it with a different number fuse as this can cause other problems.
Step 4: Put the new fuse in by reversing what was done earlier. Make sure it goes in the correct slot by checking the fuse panel diagram. Take the tongs pick up the fuse and snap it back into place. Be sure and reattach the panel as well.
This is an easy to do job and can be done by most anyone with minimal skills.
