Fuse

[quick83]

This fuse is no good. I thought until now that seldom does a glass fuse look good like this but be blown. [emoji849]. From now on I will check continuity before I install a fuse. I thought I had a blowen refrigerator power module.

Yep. Happened all the time with old cars. Would drive you nuts. While hooked up you can use a test light.

In case you don't have a meter hold one end of the fuse between your thumb and first finger. Flick the other end of the fuse using your thumb and middle finger. If the fuse is blown the element will vibrate. Have seen quite a few of these type blows over the years.

If you ever got caught without a spare one of these fuses a fired 22 rifle case was a good emergency fix. Clipped right into the old fuse holders and more than once used one to make the tail lights work on a couple of my old "beaters".

Fuses are to protect something and doing this could render a fuse useless because the circuit (item) it was protecting is gone. The old penny in the fuse socket mentality. Why did the house burn down? Great advice?

We aren't talking houses, just getting an old beater back home at night without getting stopped and getting a ticket. Did it possibly occur that maybe the reason the fuse blew was corrected (like a jack in the trunk pinching the tail light wire}?

FWIW, tubular fuses like shown are rarely used in motor vehicles anymore. More are the twin blade type, either mini or ATO type. Tubular fuses have been relegated to accessory items for the most part.
