My immutable Law Of Fuses: if you need one, buy five. If it's because you were tinkering, buy ten.

Re: R

Good rule for lots of things besides fuses. (Though I suppose it doesn't
apply to BMW's).

ps - no one seems to carry factory tested fuses ;-) ... (polyfuses excepted)

Re: R

Be sure to test the fuse for a dead short before installing it. :-)

Re: R

Oh dear! After reading this, I immediately checked all my spare fuses,
and every one was shorted. I guess a trip to the local electronics
store is in order.

Back in the old days, I used to have a flashbulb tester. Maybe I can
make a modified version of that device to test fuses. ;-)

Re: R

A "device" to test fuses? W7CSD already beat you to it with his "Little Gem
Fuse Tester" on page 94 of the April 1967 issue of 73 magazine. If you want
to see his innovative design, it is available for your viewing pleasure at
archive.org. (You can't miss it, look for Al Freddy Newham WN1ECCH on the
cover....)

No need for a trip to the store. You can clear a shorted fuse by
connecting a battery across it. Works every time.

You're welcome. :-)

Re: R

No, no, no!! The modern, HI-Tech way to do it is to build up a
circuit to charge at least a 10 F supercap and discharge it through the
fuse, thereby clearing the short. The supercap is guaranteed to
un-short almost any fuse you are likely to find, and could also be handy
for jump starting your car if using 12v to charge it. Just be sure your
charging circuit can stand the guff, those things take a heck of a jolt
without charge current limiting!!!

Tongue firmly in cheek,
