How do you test a fuse with a test light?

When to test and replace an automotive fuse?
The second is to test for electrical power at the fuse, if the sub-system that powers the circuit is not working i.e. a bad power relay, maxi or fusible link the fuse will not have power and the accessory will not work. What goes wrong? When powering an electrical circuit a designed the amperage to run the accessory is calculated by the engineer.
What to do when no power is detected at a fuse?
If no power is detected at the fuse or panel (either side of the all fuses) use a wiring schematic to trace the power source, usually a main power relay, maxi-fuse or fusible link has failed. Watch the videos! Questions? Our team of certified mechanics is ready to answer your questions for free.
What does it mean when fuse reads 12 volts?
If you read 12-volts to ground on one end but not the other, the fuse is blown and needs to be replaced. With glass fuses place the red test lead tip on the silver-colored end caps to check them. Double-check your ground connection if all the fuses read “0” volts to ground.

Where do I find the fuse on my car?
Known as a PDC (power distribution center) or fuse and relay panel which can be identified by having a black plastic cover over the top or side of the panel. Each car is different, an owners manual will indicate the location and fuse designation.
