Smoking up the Shop! CAR WIZARD shows 3 essential advanced diagnostic tools he can't live with out!

[@robertdeboer3304]

Favorite leak detector; I worked in a dealership back in 1981 fixing warranty transmission leaks. I was only paid flat rate to FIX leaks, but not to FIND the leaks. I would put car on the hoist, clean off the trans with solvent, pressure wash, dry it with air. I would then use anti-fungal foot powder spray cans like from the dollar store and "paint" powder around servos, accumulator, shift shaft, pan, etc. Quick test drive, then back on the hoist. any leaks show a very visible trail in the powder, even small porous casting flaws or cracks in the trans housing. I didn't have UV dye back then, and I only had one shot at finding ALL the leaks. I didn't get paid to pull the transmission, and fix it twice!

[@adambennett805]

Another tip for finding parasitic draw: use a thermal imaging camera to look at the fuse box for a hot fuse

[@wms201]

Can't you just use a multimeter at the fuse box?

[@adambennett805]

@@wms201 yeah but that's more laborious

[@alexm2623]

Sometimes that can work, but if it's not, you can't beat a Power Probe for speed on checking stuff like that.

[@dangerdavefreestyle]

imagine using it on the mustang that had the fan motor sucking too much juice.

[@CHixon]

Holding one in my hand as I write. Essential for comparing the exhaust and coolant temperatures between my left bank to the right bank on my Jaguar V12 5.3 Liter.

[@stephenadams5633]

Just a couple things wizard, one thank you for your service! Also, thanks for making these videos. I find it fascinating to see how you work on cars and do your troubleshooting. I’m just hobbyist mechanic myself, but I love that you share your tips and tricks!

[@jerod5636]

I lost my mind on a big Peterbilt that had a draw back when I was young and ignorant. The people who installed the winch had grabbed power somewhere weird and the inline fuse was hidden under a panel. Three. Fricken. Days. I learned to use an amp clamp after that one.

[@travisnoftle6168]

Wizard, you’re the man for sharing all of this. I learn so much from this channel!

[@petergouldbourn2312]

I love your show Car Wizard and I love Mrs Wizard too. Even though I am quadriplegic and I’ll never do these jobs myself I just find the technical side of this show fascinating. Thanks for entertaining me. Pete 🇬🇧

[@taplin7616]

Great video. I’ve learned more from you than co-workers and bosses in shops from your videos , too bad that I didn’t have a guy like you as a boss years ago.

[@yaddercamacho9714]

20:00 so, a cheaper options for those of us who dont have the money or won't buy a 80$ tool that we will probably only use once in our lifetime, using a multimeter, you can use the setting to read DC current and manually check both terminals, or better yet (but it gives a bit more work) remove the fuse, and use the fine needles in each terminal to check, not as simple, but for a thing you can DIY on your car, it is pretty useful. And a cheap multimeter is about $20 or less

[@2LateIWon]

Fyi on the amp hound make sure the doors are shut and if you have a hood light take the bulb out while testing.

[@edwardmyers1746]

Yay its the navigator! 5.4 4V too! I'm such a fan of the old lincolns i love all of them from 98- 06 and this is definitely one of em. Cars in damn good condition for being old and cheap

[@joestewart5406]

Edward Myers they are ugly horrible cars whats wrong with you

[@chipb1193]

The Amp Tester is nice because it connects to the fuses easily and works great in a professional shop but you can run the exact same test with a basic multimeter.

[@Syntappi]

Yes you can, but on modern cars unplugging a fuse and reconnecting it might wake up some modules so you get screwed with the result. With Amp hound there is no need to remove fuse so you can immediately tell which fuse is culprit for your amp draw.

[@samthenerf]

You can do exactly the same thing the Amp hound does with a good DMM, put it on millivolts and go across the fuse, this voltage drop can be translated into amperage with a chart, Power Probe has a nice one on their site. It seems like a nice product for doing things faster but you don't need it.

[@chipb1193]

Syntappi - Sam’s response above this one is what I was referencing. He sums it up nicely. No need to remove the fuses. Again, not a knock on the tool at all, or the Wizard. He’s awesome and it’s why I subscribe to his channel.

[@FishFind3000]

Sam yes, voltage drops on the fuse can be converted into amp draw.

[@luisgonzalez8423]

@@Syntappi you dont unplug fuses to test with multi meter

[@sb859]

Thank you Mrs. Wizard for all the behind the scenes camera work and editing!

[@nigel.w]

Can also use smoke machine to diagnose where water maybe entering the interior from, such as, door seals not sealing or windscreen not fully sealed.

[@kennedy796]

Yes but honestly it would be easier to get someone to spray the car with a hose while you look for the leak

[@lizardking8388]

You can test for amp draw through fuses with the millivolt function on your multimeter; no need to buy another tool. You will need to print up a chart (search "automotive fuse voltage drop chart") which will convert your millivolt readings to millamps based on the fuse size.

[@JRBRestorations]

Excellent as usual. Being a DIY person, I have learned so much from your videos. Keep up the good work.

[@masmotorsports]

Thank you so much for making this, been wrenching for 15 years now im still learning.

[@Broadshore]

Gezz Wizard.. We get it!! You Vape.. :P Anyways! The Smoke Machine is awesome to find those leaks in the cabin of the car.

[@digitalrailroader]

yup, you can look for faulty weatherstripping, out of alignment doors, leaking convertible tops, faulty HVAC doors, etc.

30 years ago these tools didn't exist. Smoke machines were called cigarettes and there was no ODB2 standard

[@GregoryBirulkin]

In the old days all we used was flammable spray for vacuum leaks. we also use propane for R12 refrigerant leaks which made mustard gas. LOL Use your volt ohm meter & Go to power probe website for fuse charts concerning amperage loss. Thank you for your videos.

[@mcdonalbennett6805]

Love your channel. Also like your way of doing business. Particularly love that you actually diagnose problems. Proves you're a first rate mechanic and not just a parts pitcher. As a retired mechanic myself I appreciate your professionalism. Keep up the great work.

I went to a technical high school for auto tech, we had a vehicle keep coming in for a parasitic drain, I stayed late one night to work on my truck and it was dark at 430 that time of year as I was leaving I saw a light coming from in the car with a parasitic drain. It was the light inside the glove compartment. I love you videos. Thank you for your service!

[@lyfandeth]

Wiz, for diy folks on a budget, the are also smoke sticks (like punks) and canned smoke, in a spray can, meant to test smoke detectors. Good for finding out where a water leak in the trunk or cabin is, if you can't spring for a whole machine.

[@Anonymous-it5jw]

Great tips. Please keep them coming. What time of day, or day of the week, do you make these videos? You always manage to present a calm atmosphere with no phones ringing and no one else working in the background - which is a great background for making these videos. Thanks again for sharing your knowledge with us.

[@greasemonkey5637]

Please do more videos like this every now and then for us mechanics. I learned a few new things.

[@ljashansen]

[@joeculver43]

The thermal image tool is amazing we have had one in the shop for years and I recently charged and started using this amazing tool I can’t wait for future problems I’ll keep y’all posted and might send a video, I work on semi’s so I see a lot of issues

[@notkevinfinnerty4959]

What I've found also works well for vacuum/boost leaks is using a charge pressure tester. You hook up shop air to the unit then use the regulator to adjust the price and spray intake area with soapy water, you'll get bubbles where your leak is. This works awesome on leaks that only present with boost present. I.e. boost leaks 👍👍

[@Itsmellsfishy]

Love these videos. I work on my own cars and having actual experience and knowledge available is great

[@haroldsegnitz7437]

[@margysan]

Great video people dont know how modern tech can help to diagnose problems. And not just with cars . Two of those items can help with plumbing and heating problems for guys fitting new systems and homeowners looking for issues in older heating systems .The smoke tester can be used to check a new installation for leaks and the thermal camera can be used for finding issues with old radiators being full of sediment .The thermal camera can also be used to identify faults in electrical / electronic circuits the uses of those two items are extensive and the cost of them is not much theses days

[@kiwiexotics1982]

My dad is a mechanic he said if your car is missing and a spark plug fouls up on a trip which you should always have spare spark plugs in your kit. He said easiest way to do a spark plug test is a spit test.You put a bit of spit on your finger and touch the manifold lightly you can hear or feel the spit get hot means its working when its not hot you know thats the cylinder needs attention. My dad always has a kit in his car a spark plug or 2 a wrench spark plug lead for the longest plug means you can put it on the short plug without problems and tyre pando points and sandpaper to clean points. We are V8 people so they are so easy to work on yourself.

[@userrrrr12366]

Omg my 2005 Honda Odyssey has a short that keeps draining my battery so my mechanic put a lever I have to undo after everytime I shut my car down so it doesn't die overnight.

8:10 I think you've never seen a forest fire and don't quite grasp "billowing." Great video. I'm the neighborhood mechanic people were coming to me with Lean codes and evap leaks. So I bought the cheapest one on Amazon $200. I had been wanting one for a while. Finally ordered it after spending way to much time tracking down a P0171 on a 2002 Lightning. It's been great, probably wouldn't stand up to frequent use in a shop though.

I made my own smoke machine. $7 for a canning jar. $7 for a 30w soldering iron. $5 for baby oil. I used an old cotton sock as the wick. I used a ball point pen for the hookups on top. I used 3 ft. of clear plastic tubing that I had from when I made my own brake bleeding kit.

Harbor Freight tools sells the "Fox and Hound." They call it a cable tracker. $23. It finds shorts to ground and broken wires. My Silverado had no power to the trailer hookup on the rear bumper. I plugged it in and ran the probe over the fuse box under the hood and found the old owner never took out the dummy fuse. I put in a good fuse and had trailer lights.

[@Louisfps]

Yes Sir that's why you're the Car Wizard, every episode is a learning experience. Thanks 💯💯💯💯👍👍👍

[@Squidforhire2]

The user should have enjoyed the laugh of, hey you found and fixed the issue, and it was something silly. It doesn't matter they could have done it themselves, they came to an expert, who diagnosed and resolved the issue. You could have sandbagged on him and said it took longer, or it was something more complex, and milked more money from them. They should be appreciative of your honesty.

[@gutsngorrrr]

The thermal camera is also great for looking at wires and circuit boards, instantly shows damaged components or wires that are overheating due to high current draw.

[@TheKnightda8]

CalVan is the manufacturer of the Amp Hound.... though the trucks sell it as well. $65 bucks on Amazon. Bought one a few months ago.... well worth it. Very cleaver to use the actual fuse an an amp shunt.

Another tool that can be used as an indicator for any temperature related issue is a $20 infra digital red laser indicated temperature sensor which you can get on e bay. They measure temperatures of bearings such as wheel bearings and auxiliary drive bearings . Just point the laser guide at the suspect bearing and it digitally shows the temperature. Great for comparing suspect wheel bearings that can be heard while driving but are hard to determine if it is right or left hand and the same for tires that a noise comes from and may be defective . You can use them in the same way the Wizard uses his display type temp reader or use them in your home to determine heat spots or cold in your ceiling where insulation is lacking or where a suspect animal is hiding in it's nest.

If it's a standard fuse just without the test points, just replace the fuse with one that has them.

[@jamesfromwellington]

Hi Wizard, One note for the viewers on the amp hound. With modern cars faults can be on different circuits to the main current draw. I had a draw from a canbus module, but the fault was due to the after-market car stereo not letting the canbus go to sleep. Incidentally, I fixed it by adding an isolating circuit to the stereo canbus signal wires

The only time I wasn't I broke out my trusty scale and would tell them if it was 2.5 or 3.1 grams because half of 1982's are zinc other half are copper.
