Does the car need to be on to test fuses or not. If so, is it safe?
The good old days back in 2018 when directions where straight to the point and simple. Thank you.
Simplest explanation of testing fuses that I’ve found and I’m not a mechanic. I’m getting a test light after watching this.
I was handed this device to check my fuses, I acted like I knew how to use it 😂
Man or woman we've been there. Either we can ask for help but that means letting the person know we don't know jack. Lol
Thank you for the thorough simple explanation!!! You have a gift! Not many can be this direct simple and easy to understand.
How do you check the big fuses?
Thanks.. Very well explained.. Simple without using technical terms so any one can understand.
Great video and helped me test the fuses in my car with my brand new test light. Super valuable video, THANK YOU!
I believe a compliment is due here :) You did a great job with this video, the timing, the info was great and easy to understand. U have a very good voice to make these videos, as well!
Does the ignition key need to be turned on to check all fuses?
Only when you check a fuse with a test light and both sides won't light up. It means there is no power running through the fuse which requires you to turn ignition to the seconds position, then test again that fuse.
Thanks for your videos. They are always very helpful and (most importantly) they are to the point! Too many wanna-be youtubers/instructors nowadays

Are all fuses supposed to light up with a test light? Some new fuses in my box wont light up but they do if i pit them in a different slot. Can some slots be bad or is it norman for some fuse slots to not have power that lights up the test light?
is it ok to do this with the engine running ? ...... great video, thanks alot
Great video. Nice and "simples!" 👍
thank you for your helpful video, can you please tell me how to test those fancy fuses with 20,30,40 A the green, blue purple ones. best regards
Would a continuity test with a multimeter lead in each port work to check if the metal internals of a fuse are blown?
How do you test the higher amp fuses (20, 30 and 40 amp fuses that surrounded that 15 amp fuse you first put the circuit tester on?They are the square flush mounted fuses. Also do they just pull out?
I want to check indoor fuses and where should I hook the clip ? There's a bare metal piece on the bottom near the pedals I guess that's a good place ?
They should have small holes in the front if not your going to have to check them one by one .🤔
The fuses that do not light up unless the key is on. Is that safe or should you remove the fuse.
Your awesome!
Thanks
Thanks so much for this valuable info!- 1A Auto helps yet again!

Is it safe to start the car or turn the key or sumn and check the fuses?

Is it better to do this with a volt meter?
Does the clip of circuit tester should always attach to negative battery . Thank you I’m beginner
Should I turn on the lights before I check the tail light fuses by test light ?
should the car be on ?? or at least the ignition switch in the on position ??
That's helpful thanks
Can I test with the ignition/engine on?
Great video.
How do you check fuses that are blocked together or has a cover on it and you can't check it with the pen?
Great
How can one check the relays with the circuit tester? They don’t have a top part to poke with the circuit tester!
Why would you have a red boot on something you connect to a negative terminal?
Love your job...
Thank u very much
good lesson. i make car fuse and fuse tap .
Do you have to start the car to check the other fuses?
How do you test those bigger square fuses?
What about the bigger square ones?
Is starting your vehicle necessary when doing these tests?
Thanks for making these videos. I'm a medical professional so IDK $*** about cars!
Question 1994 Cadillac no lights check the bulbs but I've been hearing other people talking about fuses could be bad or relays can you advise on what I need to check, and could blown fuse drain the battery also
+Antonio Davis We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
is it true that the positive side of the fuse will light up brighter than the negative side?
I installed some new fuses but and when my ignition switch is on they light up and some don't any ideas why I'm working on 03 ford ranger
Ok i got one of these but it doesn't work on fuses just a 12 volt supply what does it mean?
I tested my alternator fuse and one side is lighting up, and the other side is not, I then replaced it with another fuse and it’s still doing the same, does this mean my alternator itself is bad? I was having issues with my car dying on me , I replaced the battery and so far so good but my D light is flickering on the dash. I have a 1999 Honda Civic. If anybody could help, I will I greatly appreciate it.
The correct way is to test with a multimeter as it can test the switched fuses as well
Do you have a wiring Diagram on a 2006-2008 hyundai santa fe
Could I find a parasitic drain using this method while the car is turned off?
do I need t0 start the car before doing the light testig?
If the light on my tester is blinking when I test a fuse, what does that mean?
What about if the fuse is good but the actual outlet the fuse goes into is only lighting up on one side??

Hi, good morning. I hope you are fine. Can you help me with 2 electrical troubles of Cadillac DeVille 1998?
-The instruments cluster doesn't work, just bulbs like brake, batterie, oil, but all display is dark; I'm almost sure that the problem is the cluster (I had check fuses and they are good) abd I have seen some videos and they tell that is the cluster; and the other problem is hazard lights, I can't find the flasher. Suppose it'll be on left side of cluster but I can't find it... Do you know where is it? Thank you very much and Hi since Mexico. God bless you....
+R. Roberto Godoy Moreno We can't really accurately diagnose that without seeing the vehicle. We would recommend you take it to a reputable mechanic for diagnosis
@@1AAuto hello I have a isquemia with gmc 2000...lights inside dont always turn on when I open doors
what can we not use the test light on?
My fuses are under my Driver's side dashboard. Where are some alternate locations I can clip the light tester to, if I'm far from the main battery? Thanks!
Get a long alligator clip!
Just connect it to ground. Find a bolt or any metal
@@sullygully1976 will any bolt work?
does the car need to be on?
What if the metal in the housing only lights up on one side does that mean I have to change it ?
In the video it’s stated that if only one side lights up then the fuse is bad and needs to be replaced with a new one.
Lol 😂
How do you test the 20, 30, 40 amp fuses?
Same way just put the metal to metal from your fuse tester should let you know. All fuses from small to bigger ATC have the holes. The worst if you still having issues can be inside your vehicle under your steering wheel those are a pain in the a## . 🤔
Could only hear off and on.
??? Why not use a continuity test on the fuses instead. Then you don't have to worry about if a fuse is 'powered'. What about the square fuses? Take this video down, finish it, then repost- useless.
Hay guys I'm in deep shit 6 shops can't figer out what's wrong I gotta a 02 Honda Civic LX the car start right away but check engine blinks when rpms trying to find battery light goes on the.

Sounds like you need a new ECM
👍
Yea, but my battery is in trunk.
Tdd
AND NO MENTION IF THE CAR ENGINE SHOULD BE ON OR OFF???! 👎👎👎
Weather you turn it on or not you will still get 12.75V it’s a battery so it’s ok to turn it on if you would like .
Why? I'm trying to figure out how to work one of these things and you've got me hooking it up to the battery?? The fuse box is INSIDE the car!! How am I going to get the clamp on the battery? I'm a woman. Please stop with what a fuse is and just tell me how to work the damn fuse checker!! THIS IS Why CARS SUCK BECAUSE MEN MAKE THINGS!
