This is the best information I have found on KZbin concerning the correlation between Voltage drop and rogue current paths in DC circuits. Very well explained It's interesting that you added the tip about using thermal imagery, to pinpoint the heat signature of the excessive resistive areas in a circuit. I finally was able to afford an entry level thermal camera, and while summing all the possible uses of that device, finding temperature variations in DC circuits was among the most beneficial for automotive diagnostics for the 12 V. circuit. Of course there are many other ways to take advantage of the awesome power of thermal imaging, but it is good to hear someone bring to light the benefits of adding that device to the electronics art of automotive service and repair. Your manner of informing the viewer is very impressive and your on scene demeanor is professional. Thank you for sharing your knowledge with us, and I will be looking forward to viewing all you wish to present to us.

For the love of God, too many wires, too many bulbs, too many meters. I'm an electrical engineer and I understand everything you said. Simply demonstrate with the test light that ground is on the other side of the fuse when it should not be. Connect the test light to the battery and probe the none power side of the fuse holder. If the light turns on there is a path to ground. Disconnect the modules one at a time. If the light turns off after disconnecting then the module is shorted to ground.

Need to rewatch video a few times. But a quick question. The side of the fuse box without the power you tested. If I’m getting 2.3 volts on that side is that a short to power? With 1 lead of meter connected to ground and that side on fuse pin with fuse removed, with meter set to volts. If car matters it’s a 2012 VW CC.
@autodiagyt3 ай бұрын
That could be a few things. Water/corrosion in a connector or module causing a voltage back feed, or it could be voltage stored in capacitors inside a module. Went you see that use a small test light like a 194 bulb(250ma) to load it and see if the the voltage goes away.
@danieljurgill16813 ай бұрын
Very good. Wish you found the real short to ground...we only know TCM, Tranny Control Module. Were there green crusties in the TCM side of the connector or under the cover ? To many modules get disgarded for no reason. For the beginner in a school environment it would be best to have a schematic drawn out , so you can describe how the connections are being made. Those plastic connectors you push in and out make it hard to visualize the flow, sometimes in parallel and sometimes in series and sometimes both !
@autodiagyt3 ай бұрын
No visible damage to the TCM. What ever is shorted on the board isn’t noticeable. To further test and repair it would be more cost then the replacement salvage yard module.

I have diagnosed a million circuits for shorts or failed components in the computer repair industry over the past 25 yrs, and another hundred or so in mentoring High School Robotics over the last decade plus, and have a great understanding of exactly everything you just said and showed in your video (though I would have taken the rough of divide and conquer and always split every circuit in half...unplug in the middle, test one side, then the other, then split the offending circuit in half again (no need to even test the good side again), to find the good quarter, bad quarter, etc, rinse and repeat, since you know the other 3/4's is good, and boil it down to 1/8th, 1/16th, 1/32, eventually finding the harness short or component failure. It is just faster than tracing from battery all the way through a full circuit beginning to end. Like I said, I understand the diagnosis method, and all the tools you used, and the math behind it all (without any actual formal education in electronics or electrical engineering or diagnosis), but, what you just taught me is, without having good known good operating swap in electrical components to replace questionable components to help with the diagnosis, to actually disconnect all components from the harness first, jump across the gaps w/ leads, then test the harness first, if no faults are found, you can now test just the components next. If harness faults are found, then you will have no need to even look at the components, so no need for the addl. good known components, at least until you have repaired or replaced the harness. Then, once that harness is repaired, just disconnect from fathest away, the harness jumpers, replacing or reinstalling the components 1 by 1, until all work, or you find an offending component, and if you find one (usually damaged from the harness short), then you may have a need to have an extra good known component to add in place of a suspect component. It is the same process I have used to find buggy software in a computer registry forever. Just open the startup folder in the registry, turn off half the startup items, boot it, if the issue no longer exists, shut off the other half, turn on the other half as the issue will be there on next boot up, then turn off half again on only the offending half, if there again, turn off half again, until you find the offender software program. Each time you are just getting rid of all the searching time for more of what you need to find. And looking for shorts can be done faster using that divide by 2 process a ton faster. If I had to track down a short though in an automobile (and I did not have extra parts and components to swap in), you within a certainty would with your basic understanding of current, volts, amps, and all your basic though extensive, test lights, and multiple multi-meters available and collected by you, would be my go to guy to have you track it down. Then, I would take your extensive diagnosis and fix it. I appreciate your painstaking detail of finding a short in a car, as that is tough, as you have shown. You have the patience and perseverance of an auto electrical God! I worked on a neighbors Toyota truck that had an issue similar, a dead short in a circuit, that was even tougher to track down, and I never did so much work ever on a single circuit in my life, as it was in a brake light circuit farthest from the batter/under hood fuse and power distribution block, and it would fix and fail 3 times (over time), before I found it under dash, as someone had miswired up a replacement turn signal wand. That repair alone took lots of hrs to trace out, and we threw minor parts and rewiring at it along the way to a real final solution. I also used 8 test lights and 3 meters and a dozen jumpers on the harness at one point doing the half/half divide and conquer method to track down where the offender was located. It was flat out maddening. We finally replaced every headlight and tail light pigtail in the vehicle before we found that backward wiring issue under the dash leading to that multi-use turn signal wand (so the mis-wiring caused a couple of further shorts or overheats at a couple of the actual sockets). Once those were replaced, we found the dead short not long after. It took the patience of a Saint, and I nearly threw up my hands twice and told him to take it to an electrical guru, but I said ok, let me try again, and again. Until we fixed it.

Jake, please tell me if I am wrong. Let's say I have a circuit that has a dead short somewhere in it (I just do not know where), and it is a complicated circuit, headlights, high and low beams, tail lights, brake lights including 3rd brakelight, turn signals, towing lights plug, etc. Say it is a 20 Amp circuit. And I start at distribution block, and unplug and jumper every plug In the harness, right down to the last ground in the farthest light socket, halfway to the end I introduced a 10 Amp test bulb, put the multi- meter in just before the last ground and it reads 10 amps, that proves the harness is good correct? If so, I can discount the harness as an issue, start re-attching all the other grounds working backwards, still no issues, then it must be a component plugged in, and as I add those components back in and find a different result (it is probably that component I need a swapping component for)? I am just taking what I learned from you and adding in a time saver to the same result in half the time with fewer testing equipment costs. Jumper wires and test lights are cheaper (and easier to make up), than collecting a bunch of meters. And finding out that a harness is good first (or tracking down a dead short in one), will lead to fewer failed components or worse a fire caused. I once bought a car to race, cheap transmission cooling line crack repair, for 200 bucks, great car, but unbelievably the car had an issue I knew nothing about, a dead short in a tail light circuit, it kept blowing fuses on him, and unbeknownst to me, he had taken a blown glass fuse ACC type, and wrapped a foil wrapper for a stick of gum around it, and I found out at my very first night bracket race (first time I ever drove the car in darkness), and the very first time I actually turned on the headlight/tailight circuit, and drove the car at full throttle (of course with the alternator putting out all the (90), charging amps possible), right at the 1/4 mile 1,320' mark that my under dash fuse block was a ball of flame, now lapping up out of the right defroster plug and had flames going up the inside of the safety glass windshield hitting the passenger side visor. I stopped the car in the grass, jumped out, opened the hood, stood up in the engine bay and with sheer determination ripped the ground cable off that battery. Just about that time, the windshield blew out, safety glass shards everywhere (hood up saved me from a glass shower), just as the safety crew arrived and spraying white powder all over my black interior, and my engine bay. It took a year and a lot of trips to pick-a-parts in SoCal to rewire the car headlights to tail lights, and all points in between. I learned tons about auto electrical systems, and that dead shorts (even if not your direct fault), can be costly, very costly, and fix them fast, but fix them correctly. And that proper fusing is very important (zero shortcuts), there. I was furious when the safety crew guy, who was an actual in real life fire investigation guy w/ a local Fire Dept., found the offending wrapper (the ash film at least, that he could still read the words Juicy Fruit under a magnifying glass), wrapped around that fuse. My fault though, I boughtTrans. I wanted used but really cheap, that had another issue besides a simple cracked steel cooling line for his auto trans., and electrical issues can be really expensive and dangerous especially dead shorts. And they can ruin even your best day if they end in wire overheats and flames at speeds in excess of 90 mph.

so if you had a short to ground that would blow a 10A fuse and you put a 2A bulb in front of the fuse would it still blow the fuse

That is correct. If it's in series with the fuse it limits the current to 2 amps.

I think you have made it so hard with this bulbs there should have been easier example

I have another video showing the same thing but simplified. It's has a lot of comments and emails asking for a more detailed explanation of what I'm doing and how it works. It's more for learning the mechanics at play with this testing method.

so the bulb is your overload protection limiting the damage that can be done.

When there is a short the bulb is not lit whereas it should be lit.

If in series with the battery voltage circuit the bulb will light up when there is a short to ground.

You can be a hack like a coworker and replace the fuse with a bigger untill it doesn't blow and then have a fire behind the dashboard and wreaking a 2012 car instead of just replacing the fuse with an H7 headlight bulb like i do and look with a thermal camera to find the cable that is slightly heating up to find the actual fault. He's super mad every time i mention him burning a car that DROVE in for a radio fault that It's HIS FAULT that the car got wrecked and say's there wasn't any other way to find the fault.... 🙄

all the different color wires made it confusing, you need to state which side is the feed and which is load side of where the fuse goes, also the fact that the light has 3 wires makes it confusing.. to much going on, you could have just used the test light, not the rigged up bulb to solve this... you went by way of china to cross the street....making it confusing doesn't necessarily mean in depth... i understand what u did but most people will be lost with this ball of tangled yarn video

Too complicated. Set your meter to check continuity (the beeper). Put one of your volt meter leads on the load side of the fuse. Attach the other lead to battery ground. Leave the key off. The meter will beep if there is a short to ground. Start disconnecting the consumers on the fuse. When the meter stops beeping you found your short to ground. You don’t have to keep looking at the bulb to light up. If you want to do it at a relay unplug the relay, put the lead that was at the fuse to the relays output. Easy peasy!
@danielpantazescu77203 ай бұрын
It's not complicated at all, it's necessary. The method you're describing will be very misleading as your meter will beep the same on every load that is normal on that circuit, see the example with that solenoid that sucking 7 amps. Indeed you can do it just with a light bulb strong enough to make sense but not too strong to burn things up while testing.

How to destroy a Meter ?
@autodiagyt3 ай бұрын
It’s not complicated at all, bright light bulb is a strong path to ground, dim light bulb and there is some resistance in the circuit before it goes to ground. Your continuity test, at what resistance will it stop beeping at? How much current does it need to flow to turn the beeper on? Is the beeper even in the circuit or is the meter turning it on or off with a transistor? Until you know these things you don’t really know the limits of that testing method. I can tell you for a fact I’ve found higher resistance shorts to ground with a test light that the beeper in a meter wouldn’t find.

Jake... Question for you. Where would be a good place to find male pins that fit in fuse sockets? I want a few dozen for building test leads and lights...
