or actually using an ohm-meter instead of continuity. A test light is still too low of an amperage to show any big thermal resistance changes in bad connections. 7:11 he shows the reason why I use ohms when voltage seems to be "floating". Whenever I see voltage going somewhere but there is no real power, or amperage, "no power" situation, then I just disconnect the voltage and check the resistance, or you could just see that when the engine is on there is still below nominal on the connector, as the ABS loads the circuit down. There are of course exteremely marginal cases where some hot spots and thermal expansion can make the results unreliable, but I rarely ever had to use a test light, as it's "too" dumb. Also, don't think I'm calling Dan dumb, no, his methods are right, just not the ONLY correct way. Still I watch him to learn some interesting faults :)

I was introduced to your videos yesterday by a diagnostic friend who subscribes to you. He does this day in, day out and tries to teach me stuff. I am the kind of learner that learns by absorbing detailed information and there are so many videos out there where they talk jargon and do not really fully show what they are doing. I feel like I have learned such a lot from this video. The first one I watched was the Using Ohm's Law as I have an issue with a P0672 fault and also a P2135 fault on a Smart ForFour W454. I learned surprisingly that these two may be linked. I have yet to test and confirm. This video is just so affirming where you reaffirm every time that the lamp lights or the multimeter doesn't and then you connect the two. Although I have a test lamp, I generally use a DMM because I didn't fully understand how to properly confirm powers and grounds. Now I believe I do! At least I hope I do. The only issue for me now is getting to grips with these modern type wiring diagrams. It's easy to zone out with them and go round in circles when you're an amateur. Looking forward to watching many more of your videos irrespective of whether they are relevant or not. Working on the other half's car next with an fan relay issue P0493 and P0952 on the telematics. A garage had said that the telematics one needed a new £1100+ head unit but I am not so sure and there was a similar issue with the ABS where the unit was swapped out for a second hand one prior to my other half's ownership. Whatever happened it rectified it but leaves me wondering it was actually a similar issue. EDIT: Having read a fair amount of comments, I have concerns about whether a test lamp should be used on 5V circuits? One commentator notes test lights with different ratings 50mA, 500mA and 2A? I've not checked yet whether you have a video specific to test lamps but, if not, could you perhaps expand on this please. I don't want to go probing fuse boxes and blow anything. I guess that clamp onto negative and probing any fuse is safe but clamping onto positive, then only probe grounds and NOT touch the probe on a fuse and accidentally power a circuit that might not be 12V - is that what these commentators mean when they say you can blow circuits? If so, that should be fairly easy to remember! Thanks in advance.

I had a similar issue with my Golf IV, i.e., MK4. The alternator stopped working because it did not receive the control voltage it needed because the fuse box had some corrosion. I got stranded with a flat battery. It took weeks to figure out what was the issue and I ended up replacing the alternator in the process even though that was not the issue.

I had similar problem on a older model of nissan patrol. Friend of mine called me to take a look on his car because he had a problem with first start in the morning, especially during winter time. Conclusion was that the glow plugs are bad. Tested with multimeter, everything seemed ok, but the car wouldn't start. Checked the continuity, glow plugs, wires, both of the batteries and relay. After a whole day wasted, the last thing i wanted to try was to change the positive wire that goes from the relay to the glow plugs. Changed the wire, and it was all ok. Later checked the old wire with multimeter and multimeter said it was ok, but under the load it wouldn't deliver the power. It is important to mention that I am an electrician in construction and not for vehicles. This was the first experience with this kind of work and problems of this sort. If I had seen Dan's videos, it wouldn't have taken the whole day, only 15 minutes. Thanks Dan.

This one actually lit the test light and was very confusing for a while. Logic won the day. The voltage read ok but the test light was slightly dimmer than normal. Both together highlighted the issue - a volt drop on load.

Just something to keep in mind when you save money on Chinesium parts. You can see the battery has been recently replaced. 99% sure the previous mechanic forgot to tighten the last nut. Since it's less work to check the fuses, that's probably where I would start off. And I would still have the ABS module connected, so there would be a load on the circuit.

Hi Dan, The Volt measurement with the multimeter works fine. You have to make sure the circuit is loaded. You do this by leaving the plugs connected and performing the volt measurement by means of a back probe measurement. This is how we explain it to our students at school (Graafschap College). The way you show (test light) is of course also possible. It is true that you are now going to switch from measuring to unloaded, plug on plug off. Voltmeter to test light and vice versa. Do you have experience, no problem, if you don't, it can be confusing. KISS method: leave all connectors in place. Back probe where you want to measure. Do this with a Volt meter against ground. Correct supply 12v, correct ground 0v. Furthermore, you make great interesting videos, use them regularly in my classes! Keep it up! Regards Thomas

Wow. That was so simply explained and demonstrated. Even I could understand it. Great job, and thanks, Dan.

i fix mobility scooters for a job and i went to one that didn't work and i checked it with a multimeter and come to the conclusion the module wasn't working so i sent it off to have checked for them to send back with no fault found, then it came to me Diagnose Dan with is test light and sure enough within 10 minutes i found a bad connection, so now i have test lights in my van in my tool box and even at home, as for you're video Dan excellent video again thank you

I used to fix copiers and printers and one thing my boss told me all the time was "think low tech before you think high tech". And this video brilliantly shows us why that is.

He was absolutely right, i always tell my technicians "don't overcomplicate things"!

Thank you! I would have never thought of the advantage of using a test light! I appreciate your wisdom.👌🏾

Great display of it showing voltage, but dropping with a load. This demonstrates why it's important not to touch anything without testing it all first. These are always the weird one's that fix themselves when you wiggle too many things around, and then you never find the issue and it comes back again later. Great video!

Yes indeed, i was also lucky to catch it on video. Before you know it all is working fine again!

Nice to see VW/Audi carrying the same problems from the Golf 4 / Beetle era to the 21st century. That battery fuseholder has been similar from 20 years ago and the vehicles have been plagued by it. It controls cooling fans, turbo afterrun pump, abs and ac.

Great video Dan, the most basic diagnosis rule should be after confirming the fault, is to check your power & ground feeds... The funn6 thing is, at 11:20, KZfaq played a Nissan Qashqai ad...🤣

Excellent video Dan. I don't have a test light like the one used on this video. However, what I do to substitute is that I use a light bulb from a side marker that draws quarter amp. When reading voltages, you can connect in parallel an incandescent bulb with your multimeter. This method insures you are loding circuits being tested. Test and keep in mind how much current you are drawing with your set-up ahead of testing circuits. Thank you Dan, Love your videos.

I also use different bulbs for different circuits, pointless to use a 70mA testlight on a starter moter circuit. Thanks for your comment Dan.

Great diagnosis I can't believe that this fix can be hard for some technicians You have to be careful people out there from being paying more money because of bad diagnosis
