@fayehadleyofficial: I have certainly been guilty of this: how many of you will just pop off the fuse box cover and do a quick continuity check across the fuses in a system and then just move on? Well, I almost did that the other day, until thankfully I decided to look a little closer .... #MechanicTips #TechTips #autorepairtips #electricalrepair #cartok

Visual inspection is step 1

I had one of those fuses that would test as good when it was flipped over. If I hold it up right it would test bad.

I’ve had fuses just barely together. Test light lit up but voltage drop was bad

This is why my test light is a headlight from a car. I load test everything. I’ve been tricked by too many meters.

thats a great idea actually i should replace all the fuses i have. my suv some times doesnt charge. the alt is new.

put it under a load and demonstrate voltage drop now

Once had one that lost continuity once it heats up, stumped my brain for a bit.

I do initial test with a dvom to make sure the circuit isn't completely open but it gets followed up with a load test 👍

Continuity and ability to handle rated amperage are 2 completely different things

could that be a cause for parasitic draw

Another way is by Voltage drop before and after the fuse!!!

It's so difficult to beat this info into other techs. They have such a hard time grasping the concept that good continuity doesn't necessarily mean a good circuit. This fuse is great example of such. If you were to test it under load, it would likely have a large voltage drop.

You have to simulate a load. A resistance check will never tell you if the fuse can go up to all of the rated current. With 1 ohm, it may or it may not go.

them fuses are garbage and they are becoming more n more used

Correct the bleep activates below 50 ohms which is not and accurate resistance test.

Like an LED test light, it will light but is it 12volts or 4? Throw them in the trash 🤣

i would if they have a protective resistor to protect the curcuit or and led that lights up when blown
