Classic Car Tech-Test Light Tricks

[@1STLAR2147]

You should do a video on one of the most forgotten and mostly misused tools in existence. A simple vacuum gauge!

[@AtZero138]

Agreed... Thanks Man that's a great idea..

[@TheHermitHacker]

Absolutely!

[@eviljoker303]

I agree!My vacuum gauge even with today’s cars is still one of my most go to tuning tools!

[@Properformancenutritioncom]

That’s a must do video. Nice username...I was on Pendleton.

[@bristol831]

Why? The wife's vacuum you can see if it needs emptied or not. She knows when to empty it! 🤣🤣🤣🤣🤣

[@jerrynavarro9580]

I remember that old trick where you would unplugged the positive battery terminal and If would die it was an alternator or voltage regulator. But 1 time my smart ass co worker wanted to do that on his new car and I stop him from making a huge mistake. I told him never to do that because you could fry the ecu or destroy relays or short something out, especially on mordern vehicles. I remember when Ppl would make jokes about my 67 f100 because it was old and rusty , but the joke was on them because it outlasted their cars Lol ! Thanks for another great video uncle Tony!👍👍👍👍👍✊✊✊✊

[@AtZero138]

Oh I Get you brother... I help all my family of friends with there Cars.. Modern in comparison to my 68 Dart, and my Car, Even with Rust and needs a new interior, out runs, out starts, Runs better and Drives like a champ.. every friend I call brothers took Shop in High school, I took Art class Hahahaha.. peace Man...

[@GlamStacheessnostalgialounge]

I remember when I opened my hood to show it to my co-workers they laughed at me because "you can even see the ground through the hood!", we'll see who'll be laughing when the alternator on their fancy over-packed plastic boxes goes out, who's going to replace that!

[@MrTheHillfolk]

I hear of too many people doing this, and if you've got an alternator forget it it's toast. Unless you can react faster than the speed of light I'll guarantee you just toasted your alternator

[@GlamStacheessnostalgialounge]

+MrHillfolk I'm talking about just replacing one. On my car it's (easily) accessible from the bottom of the hood, not ideal for taking it out yourself but there's enough space to wiggle it around, meanwhile in one of my buddies' Volkswagen, the entire engine bay is playing tetris and the alternator is lodgen in somewhere between the radiator and the master brake cylinder or something, no way in hell you're taking that out yourself.

[@jerrynavarro9580]

@@GlamStacheessnostalgialounge exactly my 67 f100 was simple no ecu no fancy equipment just maybe 10 wires to the whole truck a distributor, an alternator and a carburetor that's it . People forget how cars were built back in the day that it took skillz back in the 50z and 60z to actually drive !

[@timp4634]

With each of your videos, I love my '76 F150 more and more. I also understand the truck much better now. Thanks Tony !!! Greetings from Berlin, Germany

[@chumleye1112]

You bring a tear to my eyes Tony. Old school memories of exactly what you were showing today. Thanks for carrying on the mastery and teaching this to many.

[@gmctrk63]

Eric O at South Main Auto channel has thousands and thousands of dollars worth of scanners, but his go to diagnostic tool is the test light for most things. Really enjoy your channel.

[@KennyInVegas]

I like your SHORT BUT SWEET lessons. I really like this channel. I actually learn from you.... thanks so much.

[@jeffjankiewicz5100]

Back in the day, I used to rebuild dead alternators as long as the stator and armature were good. Most of the time it was a dead voltage regulator or toasted brushes. I still have my old test light. I miss those days, no computer. Thanks for posting UTG, and dropping knowledge on us. Always a learning experience.

[@zjw3504]

As a 23 year old classic car nerd this is my favorite channel! I really appreciate the knowledge you share Uncle Tony! Thanks a million! ✌️

[@mattmischnick2926]

Another great video and thank you Uncle Tony. The test light is one of the least expensive but most loved tools in my toolbox. It never lies.

[@deplorableb.r.4211]

I didn't grow up as a "car guy", but I'm learning as I go, bits and pieces, here and there. This is a good example. Thanks for the info. I have a '69 Lincoln, so I appreciate seeing how stuff was done the "old school" way.

[@thorlarsen9770]

"Take the test light, ground it and slip it between the boot and the wire". ❤ the old skool lessons.

[@daviddntait]

People pay tuition to get an Automotive education that can only beat Uncle Tony by teaching you all the jargon and proper terminology. As for real-world, at work, making money education? Here it is people. This professor is priceless in my opinion! Uncle Tony if you read this, I want to tell you that I was taught by an ol'shool gearhead like you and I can't thank people like you enough for you have inspired me get in there and do the damn thing!

[@HammerHeadGarage]

Test lights have saved me on many occasions. They work equally great on old motorcycles too.

[@bobhunt3197]

I use this channel as a reference all the time, good information and easy to grasp. Thanks Tony, you save me money and time, and I'm learning lots.

[@fordilac]

Brings back great memories, Ramblers were great cars in their day. Most standard transmissions were ordered with "over-drive" option. I don't know the numbers but I suspect Rambler sold more (as a percentage of total sales) overdrive transmissions than any other company.

[@JDWorkshop-wn9tt]

My mom had a ‘62 Rambler with the AMC 327 until the mid ‘80s until the frame rot failed inspection. She still misses that car! I have many memories in that car before my parents bought a ‘74 Plymouth Valiant new as a second car. My first car in high school. Long gone . It’s why I found a ‘73 later in life I’ve had 14 years now. Love the channel Tony!

[@jamessilly6837]

I've also got a 73 valiant, I got a scamp with the 225 slant in it and it's just about ready for the road after restoring it

[@jasonkraus2831]

One of the challenges I've had using a test light to diagnose my (self inflicted) wiring challenges has been that I don't always have the best ground on the body since it's a freshly painted truck. But beyond that, those things are key tools. Between that, and my science-nerd multimeter with continuity testing I've been able to finally fix my turn signal issues!

[@rumrunner1756]

Thanks for bringing back another memory Uncle T. Two friends with one good battery and no jumper cables. 👍👍☮️

[@eviljoker303]

I still use the test light to locate missing cylinders .So does my brother.Thats how we found he had a faulty distributor cap on his 85 Camaro.Another cool trick for finding a misfiring cylinder is using a timing light.Hook the timing light to each spark plug wire while the car is running one at a time and the cylinder with the misfire will have a very erratic flash on the timing light(even works on cars today for finding a missing cylinder)I inherited one of those old Sears Engine Analyzers that my dad used on our cars that has the voltmeter ,ohms,tach,dwell,and amps and I still use it to this day.I agree someone said to do a video on using the vacuum gauge.Even with today’s computers and scanners a vacuum gauge belongs in every car guys tool box.They are cheap and can tell you a lot about the condition of your engine and how it’s running ✌🏼

[@googleusergp]

Very true. I have several of those old Sears analyzers and timing lights, they were all made by Actron (now part of Robert Bosch) out of Cleveland, OH for Sears. Earlier ones were made by Peerless Instruments, which Actron bought around 1983. They are solid old pieces of test equipment. One time i found one on top of a trash can on recycling day. I'm pretty sure someone wanted it to be found/taken. It was missing a couple of small pieces, which Actron mailed to me. It even had the owner's manual from 1980 included with it. It's this exact one that I had found: www.google.com/search?q=sears+161.21042&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjr2eTyk4rjAhVquVkKHRBVBPkQ_AUIEygE&biw=1920&bih=962#imgrc=JyK9enf5FLr4GM:

[@b.a.brackus6371]

My first car was a 1963 Rambler American, Salmon pink with a red stripe..l remember how easy it was to do an oil change....(because of the placement of the oil filter) Don't get me started on Present Day vehicles! How they hide everything under a foot of plastic... Sometimes l feel though l am living in the wrong era.. At least we have Uncle Tonys Garage! His insight comes from years of hands on experience...it shows. Thanks!!

[@TheHermitHacker]

Wow. I've never understood these how universal these light based testers were. I guess I'll keep one in the toolbox. 79 dodge van owner here.

[@AryDontSurf]

That's what I use, mainly because I saw my pops use one. On his janky old Pugeots and Saabs. Always stoked that you appreciate and address the utilitarianism of the inline 6.

[@feeneysmechanical6215]

I still have that style of spring clamp work light. Up here in the great white north. It was a great little heater in a one car garage. Great for warming your hands up.

[@nellietolb420]

WOW !!! My dad show me that trick on my first car in 1970..on my 65 Galaxie..he was a wizard too.. A lot of people didn't know this..you are the master..🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

[@XVIIsionsProductions]

Uncle Tony! Dude you remind me of one of my family friends, an old timer hot rodder, Kent, we called him Kent Man. He was full of knowledge and old tips and tricks and he helped me out with so many things in the past on my '77 F-150 with a hopped up 400 in it. He helped me drill and tap spiders for my roller lifters, taught me how to port my own iron cylinder heads, gasket match my intake/exhaust ports, taught me how to check for vacuum leaks using carb cleaner, tune up using a vacuum gauge, man, there was so much to learn. He passed away recently in February, Just after my 29th birthday, it really is heartbreaking. The worst part is we never got to do the burnout I promised him with the new 400 I am building that should make 550HP. I'm gonna have to go do one at his graveyard and have one of those tall Miller High life he always loved haha Keep doing your thing, I like your videos and makes me reminisce of the Kent Man. One last thing partner if you could give me an idea, I'd appreciate it. I have a stutter that has developed in my truck at 3000 RPM under load. The timing is set correct, no vacuum leaks, all cylinders are firing, new wires/plugs, idle A/F mix is good (highest vacuum at idle). When in neutral the engine revs to 5000 RPM without a hiccup, will hold steady at 3000 RPM without a hiccup, can blip the throttle over and over again without hiccup. When driving though, starting in second (4 speed manual) the engine pulls hard all the way through 5000 RPM and doesn't seem to stutter (maybe It's just not noticable?), shift to third runs up to 3000 RPM and then begins to stutter bad like its missing with a slight poofing/popping from the exhaust then as it hits 3500 RPM it starts to pull again, shift to fourth (1:1 ratio) it WILL NOT go past 3300 RPM. I've hooked a vacuum gauge up to it and ran it through the RPM's and when I crack the throttle vacuum drops as normal and then hops up then starts bouncing 2-4 mercury. In every book or reference I have found it's saying possible broken valve spring but, in the reference material it states the bouncing should get worse with higher RPM, it is not worse as the RPM increases. So I started just messing with stuff I pulled the valve covers, checked the valves/springs etc and didn't see any broken springs/rockers. Then I cleaned up the contacts on the coil/connector, checked distributor cap etc and it seemed to have fix or lessen the impact but, the vacuum gauge is still bouncing like before. A few days ago the stutter came back just the way it was before so I am trying to determine how to narrow it down and fix the problem without just stabbing parts in and hoping to fix the problem. Maybe you can help me out, I appreciate you, keep it up. -Colton

[@UncleTonysGarage]

It could be a spark control unit issue. I've had very similar things happen with Chrysler ECU's

[@340dave6]

I took my drivers license test in a 1964 Rambler Classic . This video brings back memories! Great info !

[@rustedhorsepower5132]

I remember in tech school we were taught to test tach signals for no starts with a reverse polarity test light. We even used self powered test lights for continuity checks.

[@jamesglenn6461]

I also had fitted an old seatbelt buzzer with aligator-clip leads to make an audible tester I could hear from another end of the car.

[@keithb9920]

I'm 55 not especially mechanically inclined. My first car was a 1974 firebird, then a 1969 Nova and a multitude of old Volkswagen fast backs that I used to buy out of the want ads for 500 bucks. Even an idiot like me could do all the basic repairs, and it was a lot of fun! Glad I found your channel! My current ride is in 911 which for the most part he's pretty difficult to work on. but the cost of you I'm looking for something from the 70s, some old reliable beater that I can play with and drive around.

[@notablynova]

Lol I learned at 16 the usefulness of, a 194 bulb, twelve inches of wire, and a nail to find a hot wire. Test lights are most definitely your friend. Try fixing a 30 y/o trailer harness without one lol

[@southjerseysound7340]

My grandpop showed me the same with a screwdriver. I used to save the bulb pigtails and had so many that I once made a set of Christmas lights for my shop from 194 bulbs and holders. I colored them with markers and used a 6 volt lantern battery for power to keep them from getting too hot.

[@MrTheHillfolk]

Yea, ive hillfolked up a test light by roadside with parts from the vehicle. Just hillfolk whatever you have to do to get outta there!!

[@MrTheHillfolk]

@@southjerseysound7340 Lol tech tip: Wanna color your bulbs but are too cheap to buy those colored covers or get leds? You already know paint burns off so what do you use? Carpet and vinyl spray paint for the win. Do a light coat and let it dry. Turn the bulb on for a few seconds and then off and let cool. Give another coat and repeat if you want more color. They wont discolor or burn like paint.

[@notablynova]

@@MrTheHillfolk fingernail polish works quite well as well lol

[@southjerseysound7340]

@@notablynova I've used VHT engine enamel too, but I wanted them dimmer too so I wasn't so worried about the burning. They're used every year at the shop on a Christmas tree made out of junk car parts we welded together and clear coated. The stand is a huge rotor off of a F450, the trunk is a driveshaft from something and then we made rings to weld scrap parts to that get smaller each step up. When I was building it one of my customers asked if his parts could go on the tree. So I let his kids choose where we put them on it and before you know it others joined in. I'd either let them choose where to put their parts or pick something from the pile and now they come yearly to check it out lol

[@dirtshart]

All I have to say is I've learned more watching your videos than reading any shop manual its little tricks like this that I love. My newest car is a 94 Lincoln town car and i hate it when something happens on that thing but all my other cars range from 1967-1979 and other than some of the smog crap the 79s had before I got them they are simple machines to keep running. The car I'm having the most issues with is my 86 mustang gt but thanks to a video that 50tussin did i was able to find out that my vaccum leak i knew i was wasnt actually on the upper intake plenum but was actually the vacume hose on the bottom side that went to my BAP sensor so I was able to fix that and get it running correctly once again.

[@franksgarageandcustoms8321]

Another great tech video from utg! Test light is a must have for most all electrical diagnosis. Old rambler,dad had one. Used to fall out of park if you left it idling. I got blamed for playing with the shifter when it rolled a few feet down a driveway. All i did was push it back into park.

[@devotidchannel]

ive installed a 1000 remote starts in my time and the only thing I ever used was a simple orange Snap-On light tester. It works on a Lambo or a Luv. Even old school "know it alls" like myself are being schooled here. Great channel.

I still love the way mustie1 always test the oil pressure with a test light on the VW motors he's starting. I thought that was brilliant too. I tell you I never realized until I was older how useful test lights are and diagnosing problems.

[@scottgary3008]

LOL, recently had a friend of mine who had a cylinder miss and I showed him the test light trick. He couldn't believe how simple and effective that test was.I graduated from Universal Technical Institute (Houston) in 1988 and that was a method that was still being taught back in the day.

[@Properformancenutritioncom]

Good video. The basics will really help a lot of people out. Test lights, points, vacuum gauges, timing lights etc.

[@TheCanadianBubba]

Finding where the points break was always useful for timing old beaters with missing timing tabs or spun balancer rings as well... great days to you and crew Tony.

[@jhendren0001]

I love your videos,,,i always learn something new (the test light for finding a misfire) i haven't done that one i always thought it would blow the bulb.. now i know👍👍👍

[@southjerseysound7340]

Just be sure it's not a LED and has a incandescent bulb.

[@renokowand8671]

There are two kinds of these test lights, one was basic 12volt and they other was able to handle to handle the higher voltage, they even look different.

[@michaelovitch]

One of the most used tool by most diagnostic guys on nowadays cars is still the test light. You need a scantool,a test light,an osciloscope and datas nowadays : nothing really changed. I just solved a bad plug wires problem with a test light to few days ago,on a 2009 car. Also a battery draw that you will never find with anytool is just dust between the two posts. minerals conduct electricity,and ambient air makes the job even easier.

[@LeftyLucyRightyTyty]

Had an old friend (god rest his soul)teach me how to set ignition timing with a test light, once. So freak'n simple. This only works with points style ignitions. Set the crank on the mark. Put light in series between points and coil. Loosen distributor and twist it until you find spot where light flashes on/off. Tighten distributor. Reattach points to coil. Timing DONE. Technique was actually in old school VW manuals.

U.T Completely remember doing that! Here's two I remember, Matches use to light your smokes that's a given, but as a quick fix to set your points to get ya home if you didn't have a feeler gauge tear off a match use the paper side to set points!!! 2nd Take a #2 pencil run a mark down the spark plug boot off the distributor to the next boot this trick would make the car miss fire or run rough Great trick to piss off your buddy's .

[@aussiebloke609]

I must be a fancy pants - I love my regular test light, but I occasionally also use a multimeter (oh, the shock! the expense!) and a home-made test light with a headlight bulb so I can put a bit of a load on a circuit - just in case I have a weak connection instead of no connection at all. Good to see you keeping the simple, reliable ways alive, Tony. :-)

[@topperthompson580]

Keep up the good work Tony. It could save American lives!!!

[@kenbtheman]

Nice video Tony. Those were simpler times back then. When diagnosing a problem wasn't so complex. Some of the old timers never grasped the new age automobile no matter how hard they tried and some just never tried. It's an electronic world now. It doesn't make it worse, it just makes it different. Once you get your head around the new stuff it isn't too hard. Hey I saw that you sent some things to Nick over at Nick's Garage.
