Why do I keep popping fuses?
The fuse is the incorrect amperage rating Check what devices or lights are on that circuit, as it may be the case that a new amplifier pulls too much power, causing the fuse to blow. The more devices there are on one circuit, the heavier the amp load. Fuses protect both the wiring and the devices in the vehicle.
When should fuses be replaced?
Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced. If you cannot see whether the fuse is blown, follow steps 4 and 5.
What should I replace a blown fuse with?
Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement. Step 2: Test for the bad fuse
Where can I buy spare fuses for my car?
Before you buy and replace car fuses, keep in mind that the fuse panel cover often contains spare fuses and even a fuse puller. Just be sure to replace the spares so they’ll be there the next time you need them. You can buy them at any auto parts store and at well-stocked service stations.
What to do when fuses on your car are not working?
Here are the three most common sizes of car fuses. Remove the fuse that’s labeled for the car device that’s not working, for example, the fan, radio, lighter or marker lights. Use a needle-nose pliers or a fuse puller (available at auto parts stores). Hold the fuse up to the light to see if it’s burned out.
How do you replace a fuse on a test light?
Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement. Clamp the grounding lead of your test light to a metal component. Turn the ignition key to the “run” position. Then probe both of the tiny test ports in the face of each fuse.
