Use the testing probes of the voltmeter to test the metallic ends of the fuse.
Blown ceramic fuse look like.
If you just simply replace the fuse there is a good chance the fuse will blow again.
Remove the fuse that you suspect to be blown and visually inspect the center element through the case.
This is necessary for ceramic fuses since they don t develop a blackened appearance like blown glass fuses.
A homeowner can determine if a glass fuse in blown by performing a visual inspection and looking for a break in the thin wire and a brown discoloration in the center of the fuse.
A ceramic fuse however shows no damage upon visual inspection.
To do this use a voltmeter ohmmeter.
If you see any loose objects they might be the source of a short circuit.
If you have a blown fuse take a look at the other circuitry without touching it.
Although it is fairly easy for a practiced eye to identify car fuses on sight you can also look at a visual guide to help determine which type of fuse you need to.
The more thermally stable fuse is typically filled with sand in order to prevent the conductive film from forming.
The film is formed when a short circuit melts the fuse element causing a deposit to be seen on the inside of the fuse barrel as a film.
A ceramic fuse is built to withstand high temperatures.
The melting action often causes discoloration of the case and the center element should have an obvious break.
How to rewire an australian ceramic style fuse if you have an older style ceramic fuse box you will need to change a fuse wire if it is ever blown.
Blade fuses are sometimes physically difficult to pull out but most vehicles come with a fuse puller tool that is located inside one of the fuse boxes or attached to a fuse box lid.
Check one cap on fuse pcb or manual for fuse ratings there should be written something like.
Another thing to check.
You need to test whether the ceramic fuse has blown.
Testing a ceramic fuse is the only way to tell if the fuse has blown.
